STRANGER: Then, clearly, we ought as soon as possible to divide the image-making art, and go down into the net, and, if the Sophist does not run away from us, to seize him according to orders and deliver him over to reason, who is the lord of the hunt, and proclaim the capture of him; and if he creeps into the recesses of the imitative art, and secretes himself in one of them, to divide again and follow him up until in some sub-section of imitation he is caught. For our method of tackling each and all is one which neither he nor any other creature will ever escape in triumph.
THEAETETUS: Well said; and let us do as you propose.
STRANGER: Well, then, pursuing the same analytic method as before, I think that I can discern two divisions of the imitative art, but I am not as yet able to see in which of them the desired form is to be found.
THEAETETUS: Will you tell me first what are the two divisions of which you are speaking?
STRANGER: One is the art of likeness-making;—generally a likeness of anything is made by producing a copy which is executed according to the proportions of the original, similar in length and breadth and depth, each thing receiving also its appropriate colour.
THEAETETUS: Is not this always the aim of imitation?
STRANGER: Not always; in works either of sculpture or of painting, which are of any magnitude, there is a certain degree of deception; for artists were to give the true proportions of their fair works, the upper part, which is farther off, would appear to be out of proportion in comparison with the lower, which is nearer; and so they give up the truth in their images and make only the proportions which appear to be beautiful, disregarding the real ones.
THEAETETUS: Quite true.
STRANGER: And that which being other is also like, may we not fairly call a likeness or image?
THEAETETUS: Yes.
