Lucian of Samosata De saltatione 70

[70] If what Plato ¹ says about the soul is true, the three parts of it are excellently set forth by the dancer —the orgillous part when he exhibits a man in a rage, the covetous part when he enacts lovers, and the reasoning part when he bridles and governs each of the different passions; this last, to be sure, is disseminated through every portion of the dance just as touch is disseminated through the other senses. ² And in planning for beauty and for symmetry in the figures of the dance, what else does he do but confirm the words of Aristotle, who praised beauty and considered it to be one of the three parts of the chief good? ³ Moreover, I have heard a man express an excessively venturesome opinion about the silence of the characters in the dance, to the effect that it was symbolic of a Pythagorean tenet. ⁴
