Passage 3.19.7
κατὰ δὲ τὴν ὁδὸν Ἀθηνᾶς ξόανόν ἐστιν Ἀλέας. πρὶν δὲ ἢ διαβῆναι τὸν Εὐρώταν, ὀλίγον ὑπὲρ τῆς ὄχθης ἱερὸν δείκνυται Διὸς Πλουσίου. διαβᾶσι δὲ Κοτυλέως ἐστὶν Ἀσκληπιοῦ ναός, ὃν ἐποίησεν Ἡρακλῆς· καὶ Ἀσκληπιὸν Κοτυλέα ὠνόμασεν ἀκεσθεὶς τὸ τραῦμα τὸ ἐς τὴν κοτύλην οἱ γενόμενον ἐν τῇ πρὸς Ἱπποκόωντα καὶ τοὺς παῖδας προτέρᾳ μάχῃ. ὁπόσα δὲ πεποίηται κατὰ τὴν ὁδὸν ταύτην, ἐστὶν ἀρχαιότατον αὐτῶν Ἄρεως ἱερόν. τοῦτό ἐστιν ἐν ἀριστερᾷ τῆς ὁδοῦ, καὶ τὸ ἄγαλμα καὶ τοὺς Διοσκούρους φασὶ κομίσαι ἐκ Κόλχων·
Along the road there is a wooden image of Athena Alea. Before crossing the Eurotas, slightly above the riverbank, there is a sanctuary that is shown to be dedicated to Zeus Plousios (Zeus of Wealth). After crossing, there is a temple of Asclepius Cotyleus, built by Heracles. After being healed of the wound in his hip joint ("cotyle") which had occurred in the previous battle against Hippocoon and his sons, Heracles named the god Asclepius "Cotyleus." Of all the sanctuaries built along this road, the most ancient is said to be a sanctuary of Ares. This sanctuary is on the left-hand side of the road, and both the statue and the Dioscuri are said to have been brought from Colchis.
