Suda Entry for Puge:
Puge (Butt): The part around the anus. Aristophanes writes ‘I get naked and leap to my ass.’ For, when exercising naked, they were in the habit of leaping, and the feet of the jumper would reach the buttocks. There is also the old proverb: ‘To look upon a dog’s ass.’ This is about bleary-eyed people. Indeed, they said of people with ophthalmia that they ‘look upon the ass of a dog and three foxes.’
Πυγή: τὸ περὶ τὸν πρωκτὸν μέρος. ᾿Αριστοφάνης· γυμνά-
ζομαί γε καὶ ποτὶ πυγὴν ἅλλομαι. ἐν γὰρ τῷ γυμνάζεσθαι πηδᾶν
εἰώθασι καὶ οἱ πόδες τοῦ πηδῶντος ἅπτεσθαι τῆς πυγῆς. καὶ παρ-
οιμία· ἐς κυνὸς πυγὴν ὁρᾷν. ἐπὶ τῶν λημώντων τοὺς ὀφθαλμούς,
ἤτοι ὀφθαλμιώντων ἐπέλεγον, ἐς κυνὸς πυγὴν ὁρᾶν καὶ τριῶν ἀλω-
πέκων.
