837 Et. Mag. 164. 20
Ἄτλας· ὄρος Λιβύης. Πολύιδος δὲ ὁ διθυραμβοποιὸς παρίστησιν αὐτὸν ποιμένα γεγονέναι καί φησιν ὅτι παραγενόμενος ὁ Περσεὺς ἐπερωτώμενός τε ὑπ᾿ αὐτοῦ τίς εἴη καὶ πόθεν ἀφίκ<οι>το, ἐπειδὴ λέγων οὐκ ἔπειθεν, ἀνάγκῃ ἔδειξεν αὐτῷ τὸ τῆς Γοργόνος πρόσωπον καὶ ἀπελίθωσεν αὐτόν· καὶ ἀπ᾿ αὐτοῦ τὸ ὄρος Ἄτλας ἐκλήθη. οὕτως Λυκόφρονος ἐν ὑπομνήματι (Tzetz. Lycophr. 879).cf. Tzetz. 132.18
837 Etymologicum Magnum
Atlas: a mountain in Africa. Polyidus the dithyrambic poet makes Atlas a shepherd: according to him, Perseus arrived on the scene, and Atlas asked who he was and where he had come from; and when Perseus’ words failed to persuade him (to allow him to pass), he was compelled to show him the Gorgon’s face and turned him to stone; and the mountain was called Atlas after him. So the commentary on Lycophron.2
- 1There are two doubtful fragments, rejected by Page: (1) Aristotle, Poetics 16 and 17, mentions ‘Polyidus the sophist’ in connection with the recognition scene between Iphigenia and Orestes: see T.G.F. i 248 f. (Snell); (2) Schol. Il. 24. 804a (v 643 Erbse) says Polyidus used τάφος in the sense of ‘tomb’; Erbse suggests Pindar (cf. Isthm. 8. 57, Pae. 6. 99).
