Passage 2.36.6
ἀπέχει δὲ Ἀργείων τῆς πόλεως τεσσαράκοντα καὶ οὐ πλείω στάδια ἡ κατὰ Λέρναν θάλασσα. κατιόντων δὲ ἐς Λέρναν πρῶτον μὲν καθʼ ὁδόν ἐστιν ὁ Ἐρασῖνος, ἐκδίδωσι δὲ ἐς τὸν Φρίξον, ὁ Φρίξος δὲ ἐς τὴν θάλασσαν τὴν μεταξὺ Τημενίου καὶ Λέρνης. ἀπὸ δὲ Ἐρασίνου τραπεῖσιν ἐς ἀριστερὰ σταδίους ὅσον ὀκτώ, Διοσκούρων ἱερόν ἐστιν Ἀνάκτων· πεποίηται δέ σφισι κατὰ ταὐτὰ καὶ ἐν τῇ πόλει τὰ ξόανα.
The sea at Lerna is distant from the city of the Argives forty stadia and no more. As one descends toward Lerna, first along the road is the Erasinus river, which flows into the Phrixus, and the Phrixus then empties into the sea between Temenium and Lerna. About eight stadia to the left after crossing the Erasinus is a sanctuary of the Dioscuri, named the Anakes; their wooden images here are fashioned exactly like those in the city.
