I.52.7

Πλάτων συναύγειαν τοῦ μὲν ἐκ τῶν ὀφθαλμῶν φωτὸς ἐπὶ ποσὸν ἀπορρέοντος εἰς τὸν ὁμογενῆ ἀέρα, τοῦ δὲ ἀπὸ τῶν σωμάτων ἀντιφερομένου, τοῦ δὲ περὶ τὸν μεταξὺ ἀέρα, εὐδιάχυτον ὄντα καὶ εὔτρεπτον, συντεινομένου τῷ πυρώδει τῆς ὄψεως. αὕτη λέγεται Πλάτωνι ἡ συναύγεια.

I.52.9.1

⟨Διδύμου.⟩

Ἀριστοτέλους. Ὁρᾶν ἡμᾶς κατὰ κίνησιν τοῦ κατ᾽ ἐνέργειαν διαφανοῦς· διαφανὲς δὲ οὐ μόνον εἶναι τὸν ἀέρα ἀλλὰ καὶ τὸ ὕδωρ καί τινα τῶν συνισταμένων ποθέν, οἷον ὕαλον καὶ κρύσταλλον καί τινας τῶν λαμπρῶν λίθων.

7 · A conjunction of light

I.52.7

Plato explains sight by a conjunction of light: light flows some distance from the eyes into air of like nature; light from bodies travels to meet it; and light in the intervening air, which readily spreads and changes, is drawn into tension with the fiery element of vision. This is what Plato calls the conjunction of light.¹⁹⁸¹

8 · The transparent

I.52.8

Alcmaeon explains sight through apprehension of the transparent.¹⁹⁸²

9.1 · The transparent medium

I.52.9.1

⟨Didymus.⟩

Aristotle. We see through a movement of what is actually transparent. The transparent is not only air but also water and certain things formed by combination from some source, such as glass, crystal, and some bright stones.¹⁹⁸³

1981.Synaugeia is a shining together or conjunction of radiance. The threefold account involves eye, object, and intervening air. The English provisionally takes the adjectives readily spreading and changeable with the air, as the printed construction suggests. The closing sentence is retained. Compare the longer Timaeus extract in excerpt 19.

1982.The brief report prints antilēpsis, apprehension. The apparatus records the proposal antilampsis, an answering flash or reflection, but that reading is not adopted. The precise role of the transparent remains unspecified in the surviving phrase.

1983.The Latin editorial attribution identifies Didymus, Epitome of Physics, fragment 17, Diels p. 456; the Greek heading names Aristotle. Actually transparent renders kat’ energeian, distinguishing active transparency from mere capacity. The awkward pothen, from some source, is retained rather than replaced with an unprinted classification of solids.
