We haven’t mentioned the Homeric Battle of Frogs and Mice in a while—but we are actually still working on it. There was a tradition in the early Roman Imperial period that Homer had composed the poem either just for practice or for educating children (or a combination of both). Here are some passages:
Greek Anthology, Exhortative Epigrams 90
“Because he wanted to exercise his mind,
Homer made up the tale of frogs and mice,
Which he then gave to children to imitate.”
῞Ομηρος αὐτοῦ γυμνάσαι γνῶσιν θέλων,
τῶν βατράχων ἔπλασε καὶ μυῶν μῦθον
ἔνθεν παρορμῶν πρὸς μίμησιν τοὺς νέους.
The problematic biographies, the various Lives of Homer, include some similar information.
Vita Herodotea 332-4
“The man from Khios had children around the same age. They were entrusted to Homer for education. He composed these poems: the Kekropes, Batrakohmuomakia, Psaromakhia, Heptapaktikê, and Epikikhlides and as many other poems as were playful.”
ἦσαν γὰρ τῷ Χίῳ παῖδες ἐν ἡλικίῃ. τούτους οὖν αὐτῷ παρατίθησι παιδεύειν. ὁ δὲ ἔπρησσε ταῦτα· καὶ τοὺς Κέρκωπας καὶ Βατραχομυομαχίαν καὶ Ψαρομαχίην καὶ ῾Επταπακτικὴν καὶ ᾿Επικιχλίδας καὶ τἄλλα πάντα ὅσα παίγνιά ἐστιν.
