Αἰετὸς ὁ Ζεὺς ἦλθεν ἐπ’ ἀντίθεον Γανυμήδην,
κύκνος ἐπὶ ξανθὴν μητέρα τὴν Ἑλένης.
οὕτως ἀμφότερ’ ἐστὶν ἀσύγκριτα· τῶν δύο δ’ αὐτῶν
ἄλλοις ἄλλο δοκεῖ κρεῖσσον, ἐμοὶ τὰ δύο.
(Anth. Gr. 5.65)
As an eagle Zeus came to godlike Ganymede, and as a swan to the blond mother of Helen*. So there is no comparison between the two passions**: some prefer one of the two and others the other. I like both.
* I.e., Leda.
** I.e., for boys or for women.
