Philostratus, Images 2.12.1
τί οὖν οὐκ ἐν σίμβλοις αἱ σοφαί; τί δὲ ἐν ἄστει; κωμάζουσιν ἐπὶ τὰς τοῦ Δαϊφάντου θύρας – γέγονε δὲ ἤδη Πίνδαρος, ὡς ὁρᾶις – πλάττειν κἀκ νηπίου αὐτόν, ἵν᾽ ἐμμελὴς ἤδη καὶ ἔμμουσος ἦι, καὶ ποιοῦσι ταῦτα.
Why, then, are not the wise creatures in the beehives? Why are they in the city? They go in a procession to the doors of Daïphantus [Pindar's father] – for Pindar has come to life, as you can see – and they mould him from when he is a child, so that already by this time he can be harmonious and skilled in music, and that’s what they are doing.
