Passage 2.38.1
ἐκ Λέρνης δὲ ἰοῦσιν ἐς Τημένιον---τὸ δὲ Τημένιόν ἐστιν Ἀργείων, ὠνομάσθη δὲ ἀπὸ Τημένου τοῦ Ἀριστομάχου· καταλαβὼν γὰρ καὶ ἐχυρωσάμενος τὸ χωρίον ἐπολέμει σὺν τοῖς Δωριεῦσιν αὐτόθεν τὸν πρὸς Τισαμενὸν καὶ Ἀχαιοὺς πόλεμον---ἐς τοῦτο οὖν τὸ Τημένιον ἰοῦσιν ὅ τε Φρίξος ποταμὸς ἐκδίδωσιν ἐς θάλασσαν καὶ Ποσειδῶνος ἱερὸν ἐν Τημενίῳ πεποίηται καὶ Ἀφροδίτης ἕτερον καὶ μνῆμά ἐστι Τημένου τιμὰς ἔχον παρὰ Δωριέων τῶν ἐν Ἄργει.
Going from Lerna toward Temenion—Temenion belongs to the Argives and was named after Temenos, the son of Aristomachos; for Temenos, having seized and fortified the place, waged war from there together with the Dorians against Tisamenos and the Achaeans—in this very Temenion, as one journeys there, the river Phrixos empties into the sea. In Temenion there is a sanctuary of Poseidon and another sanctuary of Aphrodite, as well as the tomb of Temenos, which receives honors from the Dorians who dwell in Argos.
