Passage 8.44.8
εἴχετο ἔτι τῆς μητρὸς καὶ ἐκ τῶν μαστῶν εἷλκεν αὐτῆς γάλα πολὺ καὶ ἄφθονον, καὶ---ἦν γὰρ τοῦ Ἄρεως γνώμῃ τὰ γινόμενα---τούτων ἕνεκα Ἀφνειὸν τὸν θεὸν ὀνομάζουσι· τῷ δὲ παιδίῳ ὄνομα τεθῆναί φασιν Ἀέροπον. ἔστι δὲ κατὰ τὴν ἐς Τεγέαν ὁδὸν Λευκώνιος καλουμένη κρήνη· θυγατέρα δὲ Ἀφείδαντος λέγουσιν εἶναι τὴν Λευκώνην, καὶ οὐ πόρρω τοῦ Τεγεατῶν οἱ ἄστεως μνῆμά ἐστιν.
He was still clinging to his mother and drawing abundant milk from her breasts. And since these events took place according to the will of Ares, they call the god "Apneios" ("Giver of Plenty"); they also say that the child was named Aeropos. There is a spring called Leukonia along the road to Tegea. Leukone is said to have been a daughter of Apheidas, and not far from the city of the Tegeans is her tomb.
