Passage 10.16.5
ἔστι δὲ ἐν τοῖς Κρητικοῖς ὄρεσι καὶ κατʼ ἐμὲ ἔτι Ἔλυρος πόλις· οὗτοι οὖν αἶγα χαλκῆν ἀπέστειλαν ἐς Δελφούς, δίδωσι δὲ νηπίοις ἡ αἲξ Φυλακίδῃ καὶ Φιλάνδρῳ γάλα· παῖδας δὲ αὐτοὺς οἱ Ἐλύριοί φασιν Ἀπόλλωνός τε εἶναι καὶ Ἀκακαλλίδος νύμφης, συγγενέσθαι δὲ τῇ Ἀκακαλλίδι Ἀπόλλωνα ἐν πόλει Τάρρᾳ καὶ οἴκῳ Καρμάνορος.
There still exists, even in my time, among the mountains of Crete, the city of Elyrus. The people there sent to Delphi a bronze goat, which is shown feeding milk to the infants Phylakides and Philandros. The Elyrians say that these children are the offspring of Apollo and the nymph Akakallis, and that Apollo lay with Akakallis in the city of Tarra, in the house of Karmanor.
