Abstract
The phrase combining the terms κάλλ0ς and ἀπoρρoή to my knowledge does not occur anywhere else in the Greek Corpus in the context of contemplating a beautiful beloved. Achilles Tatius (second centurya.d.) therefore must be making an allusion to Plato. This can hardly come as a surprise considering thatPhaedr.251, which describes the influence of the appearance of beauty on the soul of the lover, is one of the most famous and widely known Platonic passages. However, the context within which these two allusions to Plato are introduced deserves attention. Adding a certain learned touch to the description of erotic episodes in his novel, Achilles Tatius presents a ‘scientific’ explanation of the mechanism of visual perception. The consistency of both accounts suggests that he draws on some scholarly theory of vision which was part of his general educational background. But, unlike the above mentioned allusions, this theory is hardly Platonic.
