Passage 3.20.2
Θεράπνης δὲ οὐ πόρρω Φοιβαῖον καλούμενόν ἐστιν, ἐν δὲ αὐτῷ Διοσκούρων ναός· καὶ οἱ ἔφηβοι τῷ Ἐνυαλίῳ θύουσιν ἐνταῦθα. τούτου δὲ οὐ πολὺ Ποσειδῶνος ἀφέστηκεν ἱερὸν ἐπίκλησιν Γαιαόχου. καὶ ἀπʼ αὐτοῦ προελθόντι ὡς ἐπὶ τὸ Ταΰγετον ὀνομάζουσιν Ἀλεσίας χωρίον, Μύλητα τὸν Λέλεγος πρῶτον ἀνθρώπων μύλην τε εὑρεῖν λέγοντες καὶ ἐν ταῖς Ἀλεσίαις ταύταις ἀλέσαι. καί σφισι Λακεδαίμονος τοῦ Ταϋγέτης ἐνταῦθά ἐστιν ἡρῷον.
Not far from Therapne there is a place called Phoibaion, and in it is a sanctuary of the Dioskouroi; here the young men sacrifice to Enyalios. At no great distance from it stands a sanctuary of Poseidon known as Gaiaochos ("Earth-holder"). Proceeding from there towards Taygetos, one comes to a site called Alesiai; they say it was here that Myleas, son of Lelex, was the first among men to invent the mill and grind meal, and that he ground grain in Alesiai. Here also stands the hero shrine of Lakedaimon, the son of Taygete.
