Resumen

En el presente artículo examino la apropiación platónica del lenguaje poético en República y sostengo que, a pesar de sus críticas a la poesía en los libros 3 y 10, el lenguaje poético está correctamente entrelazado dentro del tejido filosófico para pintar lo corrupto, lo feo y lo inmoral. En términos específicos, la adaptación platónica de diversos motivos poéticos e imágenes en República se vuelve más significativa si prestamos atención a Sócrates como un quasi-pintor en el diálogo e interpretamos sus imágenes filosóficas como una respuesta de la filosofía a las engañosas representaciones dramáticas de la poesía. De este modo, el arte de la pintura que, incluso es criticado en el libro 10 de República, en manos de Platón resulta una herramienta filosófica que le permite investigar la relación de nuestro mundo senso-perceptivo ordinario con el campo metafísico de las Ideas y el lugar de lo humano en él.

Abstract

In this article I examine Plato's appropriation of poetic language in the Republic and argue that, despite his criticism of poetry in Books 3 and 10, poetic language is justifiably weaved into the philosophical fabric to depict the corrupt, the ugly and the base. In specific terms, Plato's adaptation of several poetic motifs and images in the Republic becomes more meaningful if we choose to pay attention to Socrates as a quasi painter in the dialogue and interpret his philosophical images as philosophy's response to the deceptive dramatic representations of poetry. Thus the art of painting, which is also criticised in Republic Book 10, in Plato's hands becomes a philosophical tool which helps him investigate the relation of our mundane sense-perceptive world to the metaphysical realm of the Ideas and humans' place in it.

Key words: Painting; Poetry; Philosophy; Plato; Republic.


 

Plato's Timaeus begins with a reference to the dialogue which Socrates had had the previous day on the organisation of the best constitution of a city-state. Timaeus' short description of the aristẽ polis, which is a summary of Books 2 to 5 of Plato's Republic, contains a rather important piece of information regarding its reception: Socrates draws in the Timaeus an explicit parallel between his theoretical, verbal construction of a polis and the life of its citizens on the one hand and viewing a representational work of art, a painting on the other:

ἀκούοιτ᾽ ἂν ἤδη τὰ μετὰ ταῦτα περὶ τῆς πολιτείας ἣν διήλθομεν, οἷόν τι πρὸς αὐτ ὴνπεπονθὼςτυγχάνω. προσέοικεν δὲ δή τινί μοι τοιῷδετὸπάθος, οἷονεἴτιςζῷακαλάπουθεασάμενος, εἴτεὑπὸγραφῆςεἰργασμέναεἴτεκαὶζῶντα ἀληθινῶςἡσυχίανδὲἄγοντα, ἰςἐπιθυμίανἀφίκοιτοθεάσασθαικινούμενάτεαὐτὰκαίτιτῶντοῖςσώμασινδοκούντωνπροσήκεινκατὰτὴνἀγωνίανἀθλοῦνταταὐτὸνκαὶἐγὼ πέπονθαπρὸςτὴν>πόλινἣνδιήλθομεν.

 "Listen to what my feeling is with regard to the polity we have described. I may compare my feeling to something of this kind: Suppose, for instance, that on seeing beautiful creatures, whether works of art or actually alive but in repose, a man should be moved with desire to behold them in motion and vigorously engaged in some such exercise as seemed suitable to their physique." (19b3-c2)1

Socrates' comment here points towards two directions: on the one hand, in the Timaeus Plato views anew the Republic's theoretical city and polity; on the other hand though, his comment foregrounds an essential question which already exists, all the same less explicitly, in the Republic: namely, what lies behind Socrates' comparison of the ideal city-state with a painting? And what would be the implications of this comparison or analogy for our understanding of Socrates' verbal depiction of an ideal city, apparently nowhere to be found on earth?

Starting from Plato's remark in the Timaeus, in what follows I would like to focus on the relation of the art of painting to the construction of philosophical speech in the Republic. What I call 'philosophical painting' in the Republic has not received much treatment in the relevant literature; nonetheless, Plato's observation in the Timaeus, as well as his several comments on the similarity of a painter's work to that of the philosopher's in the Republic, allows us to locate in this dialoguea number of 'philosophical paintings' that depict the ideal city, human nature, the acquisition of knowledge, and, most importantly, the pinnacle of the Platonic metaphysics - the supreme idea of the Good.2

Of course such a suggestion about the pictorial character of philosophic speech may lead to several interpretative problems. In Republic Book 10, it is poetry and not philosophy which is linked with the art of painting. According to Plato's Socrates, both arts share a mimetic character and both rely on "colours" (verbal-musical colours in the case of poetry) and "coloured diversity" (poikilia) to achieve the mimesis. Thus in Republic Book 10 Socrates equates the poet with the painter (both are mimetai) and develops his famous three-level scheme of Reality: the Idea, the object made by the craftsman after the Idea, and the painted image made by the painter after the Object. Within this context, Socrates argues that the craftsman is capable of using an Abstract model (the Idea) in constructing the artefact, whereas the painter is not. In specific terms, in Rep. 601 a craftsman is said to produce the reins and bit of a horse, whereas a painter merely depicts them, without having true knowledge of his theme (that is its appropriate usage). As has been rightly suggested in the relevant literature, Plato's real target in Book 10 is poetry, for which the representational art of painting appears to work as an excellent analogy. Nonetheless, in the final book Plato does reject the mimetic arts in toto for being "twice removed from truth" and for seeking to stir the emotions rather than to appeal to the rational part of the soul. In fact, according to Socrates, mimesis "destroys reason" (605b-c; cp. 606d).

Nonetheless, if we choose to ignore for a moment Plato's vehement attack on pictorial and poetic mimesis in Book 10, there are other instances in the dialogue where Plato makes Socrates compare the philosopher-king's work in the ideal polis to that of a painter, and the speech that Socrates himself employs in his philosophical exchange with his interlocutors is compared to the construction of verbal images or paintings (eikones).3 Thus if we follow, as I propose, Plato's comparison of Socrates to a verbal painter, who mixes words and motifs in his philosophical speech in the same way that a painter mixes colours to produce pictorial art, we adopt a new viewpoint which helps us cast new light on the controversial relation between philosophy and poetry.4

In specific terms, we may provide an answer to the following two questions: Firstly, what are the reasons that make Plato on the one hand severely criticise, condemn, and eventually ostracise poetry and its techniques in Books 3 and 10 of the Republic? At the same time how does he weave into the fabric of his philosophical prose in the same work themes and motifs that can be easily recognised as belonging to the poets' thematic and discursive stock? This necessarily leads us to a further question: Is the philosopher who aims to investigate the truth and reach the Real, and who condemns poetry for misrepresenting reality and deception, justifiably allowed to employ in his work the very same verbal features he rejects?

In the rest of this article I will argue the thesis that Plato's adaptation of several poetic motifs and images in the Republic becomes more meaningful if we choose to pay attention to Socrates as a quasi painter in the dialogue and interpret his philosophical images as philosophy's response to the deceptive dramatic representations of poetry. Thus the art of painting in Plato's hands in the Republic becomes a philosophical tool which helps him investigate the relation of our mundane sense-perceptive world to the metaphysical realm of the Ideas and humans' place in it.5

The Republic

But before I turn to investigate the methodological value that lies in Plato's use of painting as an analogy for philosophical speech, let me first give a short summary of the dialogue under discussion.6 The Republic's main theme is well-known: Socrates' attendance of the festival of Bendis in Piraeus brings about the grand challenge of demonstrating the importance of justice and its prevalence over injustice. In the course of the discussion it becomes evident that this undertaking is no easy task as Plato's Socrates must also show that, contrary to the opinion of the majority, the just life is the happiest form of life for humans. Indeed, for Socrates the unjust way of life is identified with the life of the tyrant and it is the worst possible choice that one could make. According to the Platonic argument of Book 9, the unjust man experiences a continuous psychological turmoil and imbalance that consumes him from the inside and also compels him to "devour" his fellow citizens in the civic courtrooms and elsewhere. Behind the choice of injustice and the unjust way of life lies one's insatiable desire for pleasure (hẽdonẽ). In the course of the dialogue, Plato also demonstrates that the pleasure of this sort is false and radically different from the true pleasure experienced by the knowledgeable and the true philosophers. Thus the subject-matter that Plato examines in the Republic is primarily ethical, but of course in Platonic thought the boundaries between ethics, politics, metaphysics, and ontology are often blurred and thus indistinguishable.

Plato investigates the nature of justice by way of an analogy, the comparison of the human soul to a city, and argues for a tripartite division in both planes. The soul is divided in three parts—the appetitive, the spirited, and the rational—and the city into three classes—the economic class, the guardian class, and the philosopher-kings. He then argues that justice in both city and soul is to be found in "each part performing its own task". It is Plato's fundamental thesis in the dialogue that correct education is the only way towards both the harmonisation of the tripartite soul and the preservation of the ideal polis, once this is created by the city founders. Socrates then devotes a great part of his discussion to laying out the guidelines and the specific characteristics of this type of education, which is directed to the city-guardians (Books 2 and 3) and the philosopher-kings (Book 7) of the Republic.

The guardians of the ideal city will be educated in mousikẽ (music and poetry) and gymnastics; the philosopher-kings' education, on the other hand, is far more demanding. In Book 7, Socrates offers a list of five subjects which are intended to free them gradually from the confusing reliance on the senses so that they can grasp the Platonic Forms. These are theory number, geometry, stereometry, harmonics and, finally, dialectic. It has been widely acknowledged that the Republic's educational programme of the guardians is essentially a reformation of current education in mousikẽ and gymnastics in contemporary Athens.7 In Books 2 and 3 of the Republic (377d7-e3), Socrates condemns the poets for "not lying well" to their audience for the things that matter most in life, namely the gods and the heroes. In this view, the poets also fail to represent correctly the "simple character" of humans (392a-b, 604e1-6; cp. Crit. 107a-108b). In Book 10 (605b8-c4), Plato's Socrates informs us that the poets fail to depict or convey a correct (re)presentation of ethical values as regards gods, heroes, and simple people because they lack true knowledge of these values. In addition, what they present (incarnate) in the various poetic performances is mixtures of antithetical ethical values: heroes who are brave but at the same time arrogant, selfish or liars; powerful but unjust and cunning; beautiful and good but cowardly.8 The consequence of poetic performances of this sort is the creation of wrong ethical prototypes, which result in the ethical confusion of the audiences.

In the Republic's terms, the knowledge of our earthly ethical values, which are manifested in the actions of humans as much as they are represented in the actions of gods, heroes, and simple people in myth and poetry is inextricably linked with a new type of philosophical knowledge, namely, one's acquaintance with the Platonic Forms. According to the ontology of the Republic, the Forms differ from their visible or sense-perceptible earthly manifestation in that, contrary to the doings in our own mundane sphere of human action, the Forms are transcendent and unchanging, eternal, pure, unmixed, and thus truly "real". In the metaphysical realm of the Platonic Ideas, concepts such as justice or beauty cannot be seen as beautiful and just from one point of view, and unjust and ugly from another. (Platonic ideas cannot be mixed thus.) This is not the case though with the sense-perceptive realm that we mortals inhabit. Ours is a world of instability, variability, and constant change; a world of mixture and continuous conflict of pairs of opposites. In Republic Book 5, Plato calls this level of cognition Doxa and argues that those who remain trapped therein and fail to move to the level of Knowledge will never attain the Real. What is more, for Plato, ethical concepts such as courage, moderation, wisdom or justice cannot be fully identified in their earthly manifestations unless one knows the Forms which make the very many particular things or actions bear the qualities that people ascribe to them.

Painting, paideia and philosophy

Fοr my purposes this observation is critical for grasping the versatile educational aspects of the Platonic Republic. In this dialogue Socrates offers guidelines for the education of the guardians and the philosopher-kings of his ideal city. Thus in Book 3 Socrates puts emphasis on the fact that the young guardians must be raised and educated in an environment devoid of "images of baseness and injustice". On the contrary, their souls will be nurtured with unmixed "images of goodness" only (401b-d). It would appear then that the ethical prototypes which Socrates favours in his educational scheme, and which the city guardians should take after, are more or less an earthly manifestation of the Platonic Forms. It is also the ethical quality of characters of this sort that the hard and demanding education of the philosopher-kings in science and dialectic is designed to perfect. 

Nonetheless, this brings us to Socrates' interlocutors in the Republic (and perhaps to the dialogue's fourth century readership), that is, to the fifth century BC people gathered at Cephalus' house in Piraeus.9 These are people of various backgrounds including metics, democrats, Athenian aristocrats, and foreigners, who, more or less, share the same cultural bonds. On the basis of the guidelines that Socrates sets in the Republic, these people can become neither guardians nor philosopher-kings in the ideal city-state because they have been culturally and cognitively contaminated in the "mud of ignorance" (535e). So what of these people that Socrates converses with at the house of Cephalus? What is Plato's philosophical and educational agenda as regards them? To put it in a different way, what sort of philosophical education does Plato hold for people who have been brought up to be confused because they have been bombarded with conflicting ethical prototypes? What becomes of people who for years listen to stories about gods who can be bribed with generous sacrifices so that they forgive injustice because gods are powerful enough to behave in this way? Who listen to stories about gods who eat their children? To stories about favoured heroes who serve the flesh of their children to the gods in common banquets? To stories about gods who literally change form (being both diverse and colourful - poikiloi) to get hold of what they desire? To stories about gods who are thieves and who fabricate empty images of smoke in order to deceive humans; stories about gods who raise wars and keep them for decades; about gods who torture humans, and about humans who torture other humans. The list of Book 2 of the Republic is long and possibly inexhaustible from Plato's point of view.10 How does Plato educate people who have been brought up not just listening to the above myths but also viewing them in, literally, numerous colourful performances? How does one educate the 'sight-lovers' of the fifth century Athens, who are used to running from 'one choral festival to another' and who insatiably attend all kinds of different performances, sophistic, rhapsodic, and poetic?11

I believe that Plato ventures an answer to this question in his Republic by making full use of the new paths and possibilities that his comparison of painting and philosophical speech can offer to an audience well-trained in viewing pictorial art representations. In other words, Plato's imagery addresses the audience's visual capacities, which have been trained anyway due to attending the various poetic performances, and builds on people's act of visualisation seeking to re-direct it towards new philosophic directions. This is achieved through the employment of an imagistic type of philosophical language (eikỡn). When employing this type of language Plato accommodates the rejected poetic modalities, imagery, themes, and motifs that are familiar to his audience. This results in the formulation of a highly poeticised philosophical prose, which both ancient and modern critics have observed, that serves as the most appropriate dialect for conveying highly complicated ethical, ontological, and epistemological concepts to people who have not been properly educated in Platonic philosophical thought, such as Socrates' interlocutors at Cephalus' house.

We are now in a better position to understand the idiosyncratic relation of philosophic speech and verbal painting in the Republic. In the last book of the Republic Plato strikes the final and severest blow against poetry: he now attacks it both on metaphysical and epistemological grounds, rigorously condemning its mimetic character.12 But elsewhere in the Republic Plato resorts to painting as an analogy for his philosophy. Socrates compares the philosopher-king with a painter who, after rubbing off his slate the various images of baseness and injustice, draws on a clean one ethics and constitutions which are only good.

λαβόντες, ἦν δ᾽ ἐγώ, ὥσπερ πίνακα πόλιν τε καὶ ἤθη ἀνθρώπων, πρῶτον μὲν καθαρὰν ποιήσειαν ἄν, ὃ οὐ πάνυ ῥᾴδιον: ἀλλ᾽ οὖν οἶσθ᾽ ὅτι τούτῳ ἂν εὐθὺς τῶν ἄλλων διενέγκοιεν, τῷ μήτε ἰδιώτου μήτε πόλεως ἐθελῆσαι ἂν ἅψασθαι μηδὲ γράφειν νόμους, πρὶν ἢ παραλαβεῖν καθαρὰν ἢ αὐτοὶ ποιῆσαι. καὶ ὀρθῶς γ᾽, ἔφη. οὐκοῦν μετὰ ταῦτα οἴει ὑπογράψασθαι ἂν τὸ σχῆμα τῆς πολιτείας; τί μήν; ἔπειτα οἶμαι ἀπεργαζόμενοι πυκνὰ ἂν ἑκατέρωσ᾽ ἀποβλέποιεν, πρός τε τὸ φύσει δίκαιον καὶ καλὸν καὶ σῶφρον καὶ πάντα τὰ τοιαῦτα, καὶ πρὸς ἐκεῖν᾽ αὖ τὸ ἐν τοῖς ἀνθρώποις ἐμποιοῖεν, συμμειγνύντες τε καὶ κεραννύντες ἐκ τῶν ἐπιτηδευμάτων τὸ ἀνδρείκελον, ἀπ᾽ ἐκείνου τεκμαιρόμενοι, ὃ δὴ καὶ Ὅμηρος ἐκάλεσεν ἐν τοῖς ἀνθρώποις ἐγγιγνόμενον θεοειδές τε καὶ θεοείκελον. ὀρθῶς, ἔφη (501a2-b7).

 "They will take the city and the characters of men, as they might a tablet, and first wipe it clean— no easy task. But at any rate you know that this would be their first point of difference from ordinary reformers, that they would refuse to take in hand either individual or state or to legislate before they either received a clean slate or themselves made it clean."

"And they would be right," he said. "And thereafter, do you not think that they would sketch the figure of the constitution?" "Surely."

 "And then, I take it, in the course of the work they would glance frequently in either direction, at justice, beauty, sobriety and the like as they are in the nature of things, and alternately at that which they were trying to reproduce in mankind, mingling and blending from various pursuits that hue of the flesh, so to speak, deriving their judgment from that likeness of humanity which Homer too called when it appeared in men the image and likeness of God." "Right," he said.13

The "slate" in this Platonic analogy stands for the human soul. On the citizens' souls, his included, the philosopher-king, as a painter, as it were, will draw virtues only, taking as his paradigms or prototypes the Forms. In line with Socrates' guidelines regarding the organisation of the ideal city in Book 5, the philosopher-ruler's aim is to create a human soul which resists conflict and strife and is as unified and thus as virtuous as possible. Along the same lines, the philosopher-king will also organise the earthly ethics and constitution of the ideal city-state. The duty that Socrates assigns to the philosopher-king in Book 5 is similar to that instructed earlier to the poets in his guidelines concerning the upbringing of the young guardians (401b-d). What is common in both is that sentiments of strife, injustice, and baseness should be erased from the ideal society (401c5-d3; cp. 462b and 470b4-9) and should be substituted with gracefulness, unity, and friendship. Yet, Socrates' task as an educator in the Republic is different from that of the philosopher-kings. Maintaining Plato's simile of painting, Socrates' "slate" as a philosopher in fifth century Athens has not been (and cannot be) wiped "clean" (see 378d). His interlocutors have been brought up with conflicted ethical prototypes: these conflicts, which result in ethical confusion, cannot be easily erased from their souls. It is to battle this ethical and epistemological confusion, I argue, that Plato compares Socrates to a painter in the Republic and has him create some of the most impressing and memorable verbal images (eikones) in Western literature.

The Platonic word eikỡn (image), which is very often translated as "simile" or "analogy" because of its etymological relation to the verb eoika (to be like, or be similar to), obliquely emphasizes the similarity between two concepts, or objects; it is also ideal to explore notions of resemblance between a copy (that is an image) and its prototype.14 From this point of view, the term bears affinities also with the concept of mimesis. Being thus pregnant with semantically loaded nuances of this sort, the term eikỡn turns out to be particularly informative in the Republic; in a dialogue, that is, which seeks to investigate the relation of our sense-perceptive world with the realm of the Forms and which aims at educating human sight so that it supports the intellect's long cognitive journey to the Forms. In the Platonic dialogues, the term eikỡn and its various cognates (eikazỡ and apeikazỡ) can be used both rhetorically to mean "metaphors, similes, and other types of verbal comparison" and, in non-rhetorical contexts, to denote a statue, a portrait, or figures in paintings. Within the broader context of art, in the Republic, the Laws, and the Philebus, the term is employed to refer to representation in music or the likeness created by actors on stage. In the Republic, in particular, the word is used in representations of bad and good characters as depicted in poetry. Outside the context of art, the term may also denote reflection on water and other shiny materials or shadow.15 But, most importantly, for the needs of my argument, in the Republic the word eikon refers to a specific type of discourse which primarily addresses our visualisation with a view to investigating complicated and highly elusive epistemological and ethical concepts. Thus, by means of a verbal image, invisible or Abstract difficult concepts are related to our sense-perceptive world, become palpable, and can be inspected.

Socrates is the only speaker to use eikones in his speech in the Republic and, when using them, he always emphasises their distinction from another type of philosophic speech, rigorous argumentation. He also underlines the inferiority of verbal image-making to the construction of philosophic argumentation. Socrates grounds his choice of this type of discourse on his own and the interlocutors' inability to follow an alternative philosophical method and/or type of philosophic speech. Thus the famous dialectic, Plato's favourite method for doing philosophy and the philosopher kings' ultimate method for ascension to the Forms, is presented in the dialogue, but is not employed in Socrates' conversation with Glaucon or Adeimantus.16

What we have instead are several lengthier or shorter verbal images: the city's guardians are compared to watchdogs (375d), and the Form of the Good is presented to the interlocutors in the image of the Sun (508e-509c). The four distinct levels of human cognition (eikasia, belief, dianoia, and noẽsis) are presented in the image of the Cave as mixtures of light with darkness (514a-517d). In Book 5, the harmonious unification of all three classes of the ideal city-state and of the tripartite soul is also presented in an image. This is the least adorned image in our text, an andreikelon, namely, the painting of a male body in carnation colour which depicts the unity, harmony, and homogeneity of all the citizens and all the souls of the ideal city-state (464b).17 At another instance in the text, Socrates presents the pursuit of philosophy by useless and incompetent people, philosophers in name only, by way of an image: philosophy is compared to a woman who has sexual relationships with men below her and who gives birth to illegitimate children; that is to other non-genuine philosophers (495c-d). In another image, the city-state which disrespects the true philosopher is similar to a ship in disarray (487b-488d). It is the incompetent and ignorant sailors-counterfeit philosophers who take charge of the ship of state in the end. 

And lastly there is the famous image of injustice in Book 9 of the Republic. Plato's eikỡn of the unjust tyrant's soul is rhetorically powerful indeed. Socrates now becomes a verbal sculptor and fashions with words the statue (eikỡn) of an incongruous, multi-headed, and wild beast to depict the soul of the unjust tyrant (588c-589b). The tyrant's soul is both the incongruent result of several wild and tame animals and a weak little man who stands for the rational part and strives to be set free, but is constantly weakened by the other 'beasts'. Socrates concludes the image by covering the tyrant's soul in a 'human flesh-coat'. The famous image of Book 9 is intended to demonstrate that there is more than meets the eye when it comes to assessing people's true power, happiness or ethical behaviour. It is very difficult indeed for human vision to penetrate the tyrant's external cover and take a good look at the intrinsic characteristics of a creature which appears powerful and truly happy, but which in fact partakes very little of human nature. The tyrant's soul is diverse, ugly, disharmonious, unjust, and truly unhappy. In other words, it is the complete opposite of what the majority think of the tyrant and of a tyrant's life.

This list is not exhaustive of all the verbal images that Socrates produces for the 'sight-lovers' in the dialogue he holds in Piraeus. It is images of this sort and not virtues (ẽthẽ agatha) that he imprints on their souls (and on ours). What is the aim of this Socratic image-making? Does it form a coherent and systematic whole? And in what way is the art of painting an appropriate philosophical analogy for the discussion of division or separation, of strife and baseness, or friendship and unification? How does this analogy relate to the verbal paintings (eikones) that Socrates produces in the Republic? I would like to argue that Socrates' image-making serves a twofold aim. Firstly, it seeks to educate the interlocutors, and all those present in the conversation at Cephalus' house, on the disentanglement of the mixtures of opposite concepts and ideas which surround us humans in the mundane world of Doxa. Thus Plato relates the verbal ornaments of poetry (chrỡmata and poikilia), its wording, distinctive themes and motifs, with injustice and the ethically confused world of Doxa.18 In doing so, he has assigned to baseness and confusion its own distinctive dialect, the poets' language.

This interpretative approach to the Republic's images becomes fully meaningful if we pay close attention to the reasons that make Socrates condemn in the dialogue not painting at large but one particular pictorial technique: skiagraphia (literally shadow-painting or shading). Shadow painting is a visual technique which flourished in the fifth century BC.19 Unfortunately, Plato and Aristotle's few references to skiagraphia are our main fourth century sources for inferring the characteristics distinctive to this particular painting technique.20 The sources suggest that the technique was based on distant viewing and relied on colour mixing to depict what one would see from afar as a "faithful" or "cohesive" representation, usually that of nature or landscapes. Nonetheless, the pictorial coherence would dissolve once one ventured a closer look at the painting. The colours then were analyzed and separated, the artistic integration was lost, and the viewer could not make sense of what previously had appeared to be a coherent whole.21

The term appears in the dialogues ten times, five of which occur in the Republic.22 Its usage and distribution in the Republic is interesting. The term is used almost exclusively metaphorically: as an analogy for deceptive poetry on the one hand, and for the mixed and non-philosophical pleasure of the many on the other. Thus Adeimantus uses it for the first time in Book 2, and Glaucon and Socrates re-employ it in Books 7, 9, and 10 to refer to the way in which the distinction of opposites can confuse and deceive the mind. Opposites are often confused. This confusion may stem either from the alternation or the simultaneous co-existence of all kinds of opposites.23

I shall return to Adeimantus' intriguing use of the term in Book 2 shortly. First I would like to focus on the context in which the term re-appears in Book 7, after, that is, Socrates has concluded his description of the ideal polis and right before he embarks on the vivid presentation of the corrupt souls and polities. In 523b Socrates is about to present to Glaucon the five lessons which are intended to free the philosopher-king from reliance on the (deceptive) senses. These are studies whose aim is to awake the intellect (noẽsis) and assist it so that it is drawn towards essence. This is no easy explication and Socrates starts from the basics. There are times when the reports of our senses help us form adequate judgments, but there are also other times when the senses seem unreliable and thus the intellect is summoned to reflect and reach judgment (523b). Glaucon intervenes at this point and employs the term eskiagraphẽmena:

ΓΛ. τὰ πόρρωθεν, ἔφη, φαινόμενα δῆλον ὅτι λέγεις καὶ τὰ ἐσκιαγραφημένα (523 b5-6).

"You obviously mean distant appearances," he said, "and shadow-painting."

But this is not what Socrates has in mind. He rather refers to:

ΣΩ. Τὰ μὲν οὐ παρακαλοῦντα, ἦν δ' ἐγώ, ὅσα μὴ ἐκβαίνει εἰς ἐναντίαν αἴσθησιν ἅμα. Τὰ δ' ἐκβαίνοντα ὡς παρακαλοῦντα τίθημι, ἐπειδὰν ἡ αἴσθησις μηδὲν μᾶλλον τοῦτο ἢ τὸ ἐναντίον δηλοῖ, εἴτ' ἐγγύθεν προσπίπτουσα εἴτε πόρρωθεν. ὧδε δὲ ἃ λέγω σαφέστερον εἴσῃ. Οὗτοί φαμεν τρεῖς ἂν εἶεν δάκτυλοι, ὅ τε σμικρότατος καὶ ὁ δεύτερος καὶ ὁ μέσος.

"The ones that don't summon the intellect, I said, are all those that don't at the same time go over to the opposite sensation. But the ones that do go over I class among those that summon the intellect, when the sensation does not reveal one thing any more than each opposite, regardless of whether the object strikes the senses from near or far off. But you will see my meaning more clearly this way: these we say would be three fingers - the smallest, the second and the middle."24

When viewed in relation to the other passages in Books 9 and 10, the above passage is crucial for our understanding of skiagraphia in that it draws attention to one specific aspect of it; namely, the utterly illusionary character of this pictorial technique. The eskiagraphẽmena are not 'provocatives' (parakalounta) according to Socrates because the viewer does not experience at the same time a contradictory perception. For the skiagraphia to work it must create the illusion of coherence and integration. And this it does through its distant viewing and colour mixture. The coherence is dropped only when the viewer approaches the painting.25

Plato uses the term again twice in Book 9 and one last time in Book 10. The passage of Book 10 sheds further light on the particulars of the technique. Skiagraphia is now linked with the deceptive appearance of objects reflected in water. According to this passage, the use of colours in skiagraphiai can have the same impact on the human soul with our perception of reflected objects in water: the viewer can reach no stable judgment as to whether a stick is straight or not. On the contrary, depending on the circumstances each thing will appear to be its opposite. In the case of skiagraphia, this is the result of the effect of its colour-mixture.

καὶ ταὐτὰ καμπύλα τε καὶ εὐθέα ἐν ὕδατί τε θεωμένοις καὶ ἔξω, καὶ κοῖλά τε δὴ καὶ ἐξέχοντα διὰ τὴν περὶ τὰ χρώματα αὖ πλάνην τῆς ὄψεως, καὶ πᾶσά τις ταραχὴ δήλη ἡμῖν ἐνοῦσα αὕτη ἐν τῇ ψυχῇ: ᾧ δὴ ἡμῶν τῷ παθήματι τῆς φύσεως ἡ σκιαγραφία ἐπιθεμένη γοητείας οὐδὲν ἀπολείπει καὶ ἡ θαυματοποιία καὶ αἱ ἄλλαι πολλαὶ τοιαῦται μηχαναί. (602c7-d4).

 "And the same things appear bent and straight to those who view them in water and out, or concave and convex, owing to similar errors of vision about colors, and there is obviously every confusion of this sort in our souls. And so shadow-painting in its exploitation of this weakness of our nature falls nothing short of witchcraft, and so do jugglery and many other such contrivances."

Nonetheless, it is in Book 9 that the richness of this art metaphor is fully divulged. Pictorial art, and skiagraphia in particular, is Plato's favourite metaphor to discuss the vexed issue of pleasure (hẽdonẽ). In 583b3-6, Socrates draws a distinction between two types of pleasure. The philosopher's pleasure is pure (kathara) and must be differentiated from the pleasure of the many which is skiagraphẽmenẽ, namely, mixed.

ἄθρει ὅτι οὐδὲ παναληθής ἐστιν ἡ τῶν ἄλλων ἡδονὴ πλὴν τῆς τοῦ φρονίμου οὐδὲ καθαρά, ἀλλ᾽ ἐσκιαγραφημένη τις, ὡς ἐγὼ δοκῶ μοι τῶν σοφῶν τινος ἀκηκοέναι

"observe that other pleasure than that of the intelligence is not altogether even real or purebut is a kind of shadow-painting, as I seem to have heard from some wise man."

In the second passage Plato refers to the mixture of pleasure and pain as an eidỡlon of true pleasure and describes false pleasure in the language of pictorial and poetic art. Poetry cultivates false pleasure only, an eidỡlon of true pleasure comparable to Helen's phantom at Troy. In this pictorial art context the mixture of colours is used to explain how sentiments of pain and pleasure are mingled in the non-philosophical majority (ὑπὸ τῆς παρ᾽ ἀλλήλας θέσεως ἀποχραινομέναις). Thus from Socrates' point of view, the pleasure of the many either contains pain or it is perceived as pleasure because it follows the feeling of pain.

ἆρ᾽ οὖν οὐκ ἀνάγκη καὶ ἡδοναῖς συνεῖναι μεμειγμέναις λύπαις, εἰδώλοις τῆς ἀληθοῦς ἡδονῆς καὶ ἐσκιαγραφημέναις, ὑπὸ τῆς παρ᾽ ἀλλήλας θέσεως ἀποχραινομέναις, ὥστε σφοδροὺς ἑκατέρας φαίνεσθαι, καὶ ἔρωτας ἑαυτῶν λυττῶντας τοῖς ἄφροσιν ἐντίκτειν καὶ περιμαχήτους εἶναι, ὥσπερ τὸ τῆς Ἑλένης εἴδωλον ὑπὸ τῶν ἐν Τροίᾳ Στησίχορός φησι γενέσθαι περιμάχητον ἀγνοίᾳ τοῦ ἀληθοῦς (586b7-c5);

 "And are not the pleasures with which they dwell inevitably commingled with pains, phantoms of true pleasure, illusions of shadow-painting, so colored by contrary juxtaposition as to seem intense in either kind, and to beget mad loves of themselves in senseless souls, and to be fought for, as Stesichorus says the wraith of Helen was fought for at Troy through ignorance of the truth?"  

Plato then has found in the technique of skiagraphia and in its colour mixture (apochrainomenais) a most appropriate metaphor to address poetry and its impact on the audience, deceptive pleasure at large, and the confusion of opposites. Elsewhere in the Republic Plato links colours (chrỡmata) with the beauty of poetry and music and argues that, if divested of them, poetry "looks" ugly (601a-b):

οὕτω δὴ οἶμαι καὶ τὸν ποιητικὸν φήσομεν χρώματα ἄττα ἑκάστων τῶν τεχνῶν τοῖς ὀνόμασι καὶ ῥήμασιν ἐπιχρωματίζειν αὐτὸν οὐκ ἐπαΐοντα ἀλλ᾽ ἢ μιμεῖσθαι, ὥστε ἑτέροις τοιούτοις ἐκ τῶν λόγων θεωροῦσι δοκεῖν, ἐάντε περὶ σκυτοτομίας τις λέγῃ ἐν μέτρῳ καὶ ῥυθμῷ καὶ ἁρμονίᾳ, πάνυ εὖ δοκεῖν λέγεσθαι, ἐάντε περὶ στρατηγίας ἐάντε περὶ ἄλλου ὁτουοῦν: οὕτω φύσει αὐτὰ ταῦτα μεγάλην τινὰ κήλησιν ἔχειν. ἐπεὶ γυμνωθέντα γε τῶν τῆς μουσικῆς χρωμάτων τὰ τῶν ποιητῶν, αὐτὰ ἐφ᾽ αὑτῶν λεγόμενα, οἶμαί σε εἰδέναι οἷα φαίνεται. τεθέασαι γάρ που [...] ἔοικεν τοῖς τῶν ὡραίων προσώποις, καλῶν δὲ μή, οἷα γίγνεται ἰδεῖν ὅταν αὐτὰ τὸ ἄνθος προλίπῃ (601a-6).

 "And similarly, I suppose, we shall say that the poet himself, knowing nothing but how to imitate, lays on with words and phrases the colors of the several arts in such fashion that others equally ignorant, who see things only through words, will deem his words most excellent, whether he speak in rhythm, meter and harmony about cobbling or generalship or anything whatever. So mighty is the spell that these adornments naturally exercise; though when they are stripped bare of their musical coloring and taken by themselves, I think you know what sort of a showing these sayings of the poets make. For you, I believe, have observed them." "I have," he said. "Do they not," said I, "resemble the faces of adolescents, young but not really beautiful, when the bloom of youth abandons them?"

Although it is not my aim to enter here the tantalizing art history discussions which seek to throw light on the exact specifics of the technique, I believe we cannot fully understand the philosophical richness of this pictorial metaphor without paying attention to the technique's use of colours.26 Vincent Bruno's comments are very enlightening in this direction. According to Bruno, in the painting of skiagraphia, "gold as well as other bright and valuable colours, such as murex purple, lost their aesthetic value shared in earlier times. What was more important in the new painting attitude was the description of space and volume by the alternative application of light and dark tones as well as of subtle warm and cold hues."27 In his treatment of the technique he offers an enlightening description of the viewer's experience of a fifth century skiagraphic painting: "If we stand at a distance from a painting represented in three dimensions by means of some coherent system of dark and light, we see that each garment, each chair, each head of hair has a colour which we can easily discern and even name.... Yet the moment we were to step up closer to the picture, the entire situation would change, for it would soon become obvious that the real colours of which the picture is composed are not at all as those we named in our analysis of the overall design. It would become clear that the shadows of folds in the white of the cloaks were full of unexpected strokes of blue and violet..."28

Plato likens this viewing experience of the fifth century Athenian to poetic deception and contrasts it to his philosophy and the restorative effect of his own philosophical image-making. According to this interpretation, poetic performances build on contradiction and confusion of opposite ethical concepts and create similar, though mixed, pleasures to their audience. In Plato's philosophical prose, traditional vision (theasis) has been substituted by visualization (what could be called enargeia) with Plato employing poetic language (traditional poetic words, themes, and motifs) to make philosophic images (eikones) that present ethics and politics in the correct light. Thus, for example, the psychological image of the multi-headed beast-tyrant traces its origins in Hesiod's Typhon,29 while the image of the ship of the State in disarray evokes the poem of Alcaeus (46a D.). Verbal painting has worked successfully indeed, for some of Plato's images in the Republic are among the most memorable in Western literature.

We can now return to Adeimantus' early employment of the term skiagraphia in Rep. Book 2. Adeimantus introduces the term in his analysis of how one should find a balance between justice and injustice; namely, be unjust in the inside but appear just from the outside: περὶ ἐμαυτὸν σκιαγραφίαν ἀρετῆς περιγραπτέον, τὴν δὲ τοῦ σοφωτάτου Ἀρχιλόχου ἀλώπεκα ἑλκτέον ἐξόπισθεν κερδαλέαν καὶ ποικίλην (365c3-6). The language he uses to promote this anti-Socratic idea regarding real life ethics is distinctively poetic. Far from rejecting this discourse, Socrates will re-employ it in Books 8 and 9 to describe the rejected, corrupt, and unjust polities. Plato, I argue, has associated from the beginning this pictorial technique with poetry and with the deception that results from its confusion of ethical opposites. We are still early in the dialogue, but Plato's Socrates is preparing artistically the ground for bringing together poetry and the deception which stems from its mixture/confusion of ethical opposites with this particular technique, which relies on colour-mixture to create (illusionary) integrity and cohesion.

The categorization of the Republic's images

I have already suggested that through his images Plato seeks to educate the Republic's "sight-lovers" and demonstrate how poetry and its language should be linked with specific psychological, ethical, and political conditions. With this interpretation, the philosophical images may be organized in three groups: a) images of human nature and polities (ethics), b) images of knowledge and its attainment (epistemological images), and c) images about the truly Real (ontological images). In making these images Socrates is careful to employ language fittingly. Thus the "diverse" and "colourful" language of the poets is given a specific place in the Platonic philosophic discourse and ethical system. Poetry's verbal colours (chrỡmata and poikilia) are linked with instability, conflict, polymorphy, and variety. Socrates, on the other hand, handles imagery in a different manner in his epistemological images of the Line and the Cave and in the ontological image of the Sun.

The paintings of ontology and epistemology

In Republic Book 6 (507a-509b), the image of the Good as the Sun constitutes the pinnacle of what I have called Platonic philosophical painting. From this interpretative point, Plato's image of the Sun becomes the measure by which we may assess the Republic's various paintings. Through this image Plato tries to show how the Form of the Good assigns meaning to all the other Forms as well as to difficult concepts such as knowledge and truth. Socrates' analogy highlights the simplicity (haplous) and purity (katharos) of the most significant Form. To grasp the supremacy of the Form of the Good, Socrates' interlocutors are asked to visualize the Sun. But if we reflect on the pictorial effects of this image, we find illustrated Socrates' response to the various poetic shadow-paintings (skiagraphiai). The Sun's homogeneity and purity of light does not allow for any form of colour mixture, shading or optical fusion. Neither does it allow for the illusion of perspective or depth. On the contrary, the interlocutors are asked to see the unmixed white, since the Form of the Good in itself cannot be mixed.30 It is not Good in relative terms; i.e., good from one point of view, but bad from the other. On the ontological level of the Platonic Forms, the relativity of the human perspective is absent. And along with it so is the poets' language with their diverse themes and motifs. Plato may have resorted to an image in his presentation of the Sun, which otherwise can be approached only through dialectic, but he has kept this memorable image as unadorned (a non poikilẽ) as possible.

However, things change once the human perspective is introduced in this picture. In the epistemological images of the Line (509d1-511e) and the Cave (514a-517d), Plato introduces the Pre-Socratic and poetic motif of mixture of light and darkness, which generates shadows, as well as the recreation of the physical environment by way of reflection, to demonstrate how true reality can be fabricated (agalmata), distorted (shadows), and misperceived. In the Cave, in particular, he has invented insightful imagery to draw attention to the confusing mixture and enlightening analysis of pairs of opposites. Plato's framework for the epistemological image of the Cave is of poetic origin. The contrast of light and night/darkness is linked with the traditional myth of katabasis, thus evoking the heroes' visits to the underworld.31 But this traditional theme too is re-worked in Plato's hands, for his own katabasis, contrary to its poetic precedents, is a plunge into darkness and with it, ignorance and deception.32

Images and paintings of psychology and politics

It is in the depiction of corrupt souls and polities, though, that poetic diction predominates.33 Socrates starts with the traditional image of the State as a ship to describe the society which disrespects and finally subverts its "deaf leader", the philosopher (488a), and culminates in his imagery (eikỡn-statue) of the soul of the tyrant (588c-d). What comes in between, in Books 8 and 9, are several shorter images dressed in the language of poetry to describe the ethical and political decline. And the more corrupt the city and soul, the more Socrates resorts to the language of poetry (iambus and Comedy) to describe it. Thus the democratic city, the representative of coloured diversity par excellence, is compared to a poikilon himation ornamented with all sorts of flowers (anthesi).34

The citizens, on the other hand, are similar to their poleis: In the oligarchic man, evil appetites transform him into a "drone" (552c2-4).35 In democracy, on the other hand, one can find diverse and multifarious people, with all sorts of features (ἰσονομικοῦ τινος ἀνδρός... παντοδαπόν τε καὶ πλείστων ἠθῶν μεστόν, καὶ τὸν καλόν τε καὶ ποικίλον, ὥσπερ ἐκείνην τὴν πόλιν... (561e). The citizens of this polis resemble all sorts of animals: "beasts", "dogs", "horses" and "donkeys" (θηρία, κύνες, πποι, νοι 563c-d).36

Still, it is for the description of the tyrant, the representative par excellence of ethical baseness and injustice, that Socrates fashions not a painting, but a verbal statue with the colours of poetic language. His aim is to lay bare for the sight-lovers to see a despicable soul which cannot be admired. The sight-lovers also learn that traditional poetic discourse is appropriately used only when it describes psychic turmoil, injustice, and badness. They also learn that poetry and its language, which traditionally caused pleasure (hẽdonẽ), when viewed under the right light, can only bring pain and terror. The poikilia of the unjust is ugly; the pleasure they enjoy is mixed, torturous, and false; their actions make them subhuman.

On the other hand, it is not fortuitous that poetic words and traditional motifs are not present in Book 5 of the Republic, where Socrates describes the ideal city and life in it. In Book 2 (375d5), Socrates had compared his guardians to watch-dogs, but this peculiar image, which was intended to investigate the features of the best human physis, is left behind as we move to the ideal city. As I suggested earlier, the only Platonic image (eikỡn) of the central book is a male body figure (an andreikelon) through which Socrates strives to depict the simplicity and harmonized unity of the many into one (462c10-e2; 464b1-3). This unification is intended to stand in stark contrast to the polueidia of the tyrant and the confusing poikilia of the corrupt polities. It would also seek to emulate the true Reality of the One which can only be attained at an ontological level.

Conclusion

Contrary to the viewpoint which has interpreted Plato's stance towards painting as derogatory, in this article paper I have tried to show that Plato's treatment of it, far from being so straightforward, is intended to serve several needs.37 Thus painting is for Plato an analogy which allows him to discuss vexed philosophical issues and has provided him with useful vocabulary for his philosophical investigations. Behind the diverse treatment of the art of painting in the dialogues lies the versatile Platonic notion of mimesis. The term which is discussed in Rep. Books 3 in relation to poetry, in Book 10 and elsewhere in the corpus becomes epistemologically significant and can refer to the relation of our mundane world of change with the fixed Realm of the Forms, to the ability of language to formulate statements that may represent faithfully either the world, or to the metaphysical Real (the Cratylus, the Sophist). The Republic's verbal paintings should be viewed in this light: as verbal images which help the sight-lovers review, or view anew, their beliefs about ethics and politics.38

For Plato, philosophy is anyway a cognitive journey of vision (a theỡria) with many levels but a specific target, the Forms.39 His inventive metaphor of painting and his association of poetic words with colours allowed him to demonstrate how his own philosophic image-making differs from that of poetry. The philosopher knows how to use language correctly in his discourse in order to investigate both the sense-perceptive and the invisible reality. The poet does not. Plato's images render his philosophical speech mimetic too. Yet this is the positive aspect of mimesis: images and copies when used correctly support knowledge and function as cognitive levels, which in turn can lead us to the Forms.

2 This is an elaboration of some points of chapters 3 and 4 of my book The poetics of philosophical language (2011). In this article I have expanded and refined the issue of the pictorial art of skiagraphia and supplemented the bibliography. 

3 Rep. 501a2-b7; See also Rep. 484c6-d3 and 517d-e.

4 Socrates compares himself to a painter in Rep. 487e4-488a7, but he has already made a number of images in the text and will continue to build even more impressive ones as the conversation progresses. See also Rep. 399e5-10. Several interesting studies have offered insightful analyses of the vexed issue of philosophy's ancient quarrel with poetry. See, for example, Ferrari (1987) and (1989), Nightingale (1995), and Halliwell (1988) and (2000b). In addition, see the several enlightening analyses in a volume focused on this idiosyncratic relationship in Destree, P. and Herrmann, F.-G. (eds.) (2011). In this paper I focus instead on the way the art of painting may help us grasp the reason why Plato attacks the representational-performative aspect of poetry. See also Petraki (2011: 8-18).

5 Halliwell (2000a: 102-3). Note that in Cratylus 431a-d, which antedates the Republic, Plato links again words with colours and associates logos at large this time with painting, mimesis and image-making.

6 In the summary of the Republic in the following paragraphs I restate ideas which I have discussed in Petraki (2011: 1-2). 

7 See, for example, Clay (1988: 18-33) and Rocco (1997).

8 That Plato views this as a problem in the Republic is evident from 604e-605b. This "clash" of character features is a vexed issue which relates to the successful harmonization of the tripartite human soul. A detailed discussion of this issue lies outside the scope of this paper. In her analysis of thymnos in Plato Angela Hobbs discusses this "clash" in the Hippias Major and the Hippias Minor, but, in her view, Plato does not view it as a problem in these two dialogues (Hobbs 2000: 175-219). The problem of the conflicting characteristics is raised for the first time in the Republic. Although I agree with Hobbs that Plato does not address this problem in the two shorter dialogues, I am more inclined to detect an irony on his part in the way he has Socrates converse with Hippias about these two traditional heroes. According to my reading, Plato recognizes the problem but does not address it explicitly as he does in his Republic, where Socrates has a different philosophical agenda and interlocutors.

9 I am here referring not only to the two main interlocutors of Socrates throughout the dialogue, Glaucon and Adeimantus, but also to the several dramatic personae of Book 1, Polemarchus, Lysias, Euthydemus, and Thrasymachus, to name some of them, most of whom participate in the dialogue on justice as mere listeners. There is a growing literature on the dialogues as dramas as well as on people which surround Socrates. See, for example, Arieti (1991), Stokes (1986), Blondell (2002: 1-80) and Petraki (2011: 26-30 and 142-155 with further bibliography). In addition, see Nails (2002).

10 Note that all of the above, and yet more according to Socrates, are to be erased from the poetic myths that the guardians will be listening as they are being brought up. See Rep. Book 2 and 3.

11 See Rep. 475d1-8: οἴ τε γὰρ φιλοθεάμονες πάντες ἔμοιγε δοκοῦσι τῷ καταμανθάνειν χαίροντες τοιοῦτοι εἶναι… ὥσπερ δὲ ἀπομεμισθωκότες τὰ ὦτα ἐπακοῦσαι πάντων χορῶν περιθέουσι τοῖς Διονυσίοις οὔτε τῶν κατὰ πόλεις οὔτε τῶν κατὰ κώμας ἀπολειπόμενοι. ["You will then be giving the name to a numerous and strange band, for all the lovers of spectacles are what they are, I fancy, by virtue of their delight in learning something...  but as if they had farmed out their ears to listen to every chorus in the land, they run about to all the Dionysiac festivals, never missing one, either in the towns or in the country-villages.] The text of the Republic used is Burnet's OCT (1903) edition. I have also consulted Slings' 2003 OCT edition.  

12 This comparison has generated the opinion dominant in the relevant literature that Plato's view of painting is primarily, if not only, negative. See Schuhl (1952, rpr.), Demand (1975: 1-20), Plochmann (1976: 189-200) and Morgan (1990: 23: 121-145). See also Hub (2009).

14 On what follows see also Pender (2000: 7) and Silk (1974: 5). See also Vernant (1991: 164-185), Gallop (1964/65: 113-131), Said (1987: 309-30). In addition, see Radke-Uhlmann (2011: 153-179). I have discussed in detail the notion of Plato's eikỡn in Petraki (2011: 58-69). 

15 On Plato's use of the epistemological imagery of reflection and art representation in the Line and the Cave, see Petraki (2009: 27-68) with further bibliography.

16 See Rep. 506d-e; cp. 532d-533a.

17 On andreikelon see Keuls (1997: 115-6).

18 Poikilia (colour diversity) traces its origins both back to Homer and to the Pre-Socratics. In the art context it is linked with music, painting, and embroidery. In Plato it also refers to the vivid and diverse colourfulness of our sense perceptive world, which can deceive the intellect (see, for example, Rep. 529d-e). Note that in the Pheadrus 247c true reality is presented as colourless. On Plato's view of the concept of poikilia in philosophy see Wallace (2009: 201-213). See also extensive discussion in Petraki (2011: 15-6 with ns. 28 and 29 and 177-214). With regard to poikilia in poetry and music, see Fowler (1984: 119-149), Barker (1995: 41-60), Roch (2001), Rocconi (2004: 29-34) and LeVen (2013: 229-242).

19 The technique of skiagraphia, apparently a breakthrough in pictorial representation of the fifth century BC, has been linked by some with the very birth of painting. As Pliny himself acknowledges, 'the question of the origins of painting is uncertain…' (N.H. 35. 15-16; cp. his comments in N.H. 35. 58-60 on Apollodorus the skiagraphios: 'he first established the method for representing appearances and first conferred glory upon the paintbrush iure.) According to Plutarch (De Gloria Atheniensium 2 [Mor. 346A]), the technique was developed by Apollodorus of Athens in the latter part of the fifth century who was for this reason called skiagraphos: Scoliast on Iliad 10.265, s.v. πῖλος ἀρήρει; Hesychius, s.v. σκιά: ἐπιφάνεια τοῦ χρώματος ἀντίμορφος; Photius s.v. σκιαγράφος; RE s.v. 'Apollodorus' no. 77. In addition, see Overbeck 1641-47.

20 The skiagraphia is a highly contested technique. See Keuls (1975: 1-16), Pemberton (1976: 82-84), Pfuhl (1910: 12-28) and (1912: 227-31); Also, Steven (1933: 149-55), Pollitt (1974) and Trimpi (1978: 403-413). However, the wall paintings found in the Macedonian tombs at Phoenikas and Hagios Athanasion in Thessaloniki have cast new light on the controversies. See its detailed description offered in Τσιμπίδου-Αυλωνίτη (2005).

21 Ascertaining the technical details has been no easy task. There has been particular controversy over the creation of 'shading' (skia). Namely, the manner in which colours were mixed to create hues, and its relation to the pictorial technique of skênographia (scene-painting). As both trace their origin in the Classical era some scholars have argued for their identification. According to this view, skiagraphia/skênographia was a technique invented for the theatre. It sought an imitation of reality by way of visual trickery and is best translated as 'trompe l' oeil' (Rouveret [1989: 24-5]). As regards the Platonic corpus in particular, the view has been taken that the two techniques have been confounded, with Plato using the term skiagraphia to refer to skênographic representation as well. This is Trimpi's view (1978: 403-413) who, nonetheless, argues that Plato does not use the term in all the textual environments in the same way. Thus behind the term skiagraphia-skiagraphemena may lie the technique of skẽnographia depending on the context. According to Trimpi, in the long history of the two terms the distinction became philologically obscured and the terms skiagraphia and skênographia became interchangeable and remained so for Hesychius and Photius in the Middle Ages.

22 With the exception of the Phaedo 69b, Plato uses the term in the Republic and in the late dialogues. See also Parm. 165c-d, Tht. 208e, Crit. 107c-dand the Laws 663b-c. Different dialogues highlight different aspects of the technique. In the Critias 107c-d, Critias informs us that the "unclear and deceptive" skiagraphia is adequate for the representation of landscapes and broad vistas, but not for the representation of human bodies. According to the Theaetetus 208e, this technique requires remote viewing. Should the viewer approach the painting, coherence broke up and the representation makes no sense at all. The Parmenides 165c-d provides us with further information. The skiagraphia uses mixture of colour and requires distant viewing. In the Parmenides the technique is used as a metaphor for "the unreal divisions of the one". Thus what appears to be "one" from afar (ἀποστάντι μὲν ἓν πάντα φαινόμενα) soon turns into "many", "different", and "dissimilar" (προσελθόντι δε γε πολλὰ καὶ ἕτερα καὶ τῷ τοῦ ἑτέρου φαντάσματι ἑτεροῖα καὶ ἀνόμοια ἑαυτοῖς). These three dialogues aside, Plato uses this art metaphor in the Phaedo, the Republic, and the Laws to discuss the vexed concepts of pleasure and justice.

23 See Rep. 523b and 602c7-d4 with the discussion further below. At an ethical level this would mean that one is truly unjust but appears in a manner similar to a straight stick which appears bent.

24 Translation after Bloom (1968).

25 That this is a characteristic feature of this technique is evident from Socrates' comments in the Theaetetus 208e and the Parmenides 165c-d. 

26 Note that in Plato colours and coloured diversity is often linked with deceptive multiplicity and diversity and is thus criticised and rejected (see Symposium 211e; but cf. Phaedo 110b-d, Philebus 51d, and the Seventh Epistle 342d). See also Timaeus 68d. On colours see Gaiser (1965), Crone (1999) and Ierodiakonou (2009).

27 Bruno (1977: 80). See also Walter-Karydi in Tiverios and Tsiafakis (eds.) (2002: 76): 'In archaic age painters used pure colours - they now mix them creating hues that lie between the primary values'.

30 On the use of white colour in the fifth century technique of skiagraphia, see Bruno (1977: 58-9). Bruno observes that for the ancient painters white would have been the equivalent of light.

31 The contrast of light and night has a long history in poetry and in Pre-Socratic philosophy, starting from Homer to the end of the fifth century. With regard to poetry, see the detailed discussion in Irwin (1974: 157-200). See also Tarrant (1960: 181-187) and Notopoulos (1944: 163-172).

35 Βούλει οὖν, ἦν δ' ἐγώ, φῶμεν αὐτόν, ὡς ἐν κηρίῳ κηφὴν ἐγγίγνεται, σμήνους νόσημα, οὑτω καὶ τὸν τοιοῦτον ἐν οἰκίᾳ κηφῆνα ἐγγίγνεσθαι, νόσημα πόλεως; Cp. Hesiod Works and Days 304ff.; Αrist. Wasps 1114.

36 Plato bases his description of democracy and tyranny on poetic wording. The poikilia and polueidia of these two constitutions requires all sorts of verbal colours (anthẽ). See Petraki (2011: 237-254). See also Adam (1963/[1902] vol. 2: 232).
