Passage 2.38.2
Τημενίου δὲ ἀπέχει Ναυπλία πεντήκοντα ἐμοὶ δοκεῖν σταδίους, τὰ μὲν ἐφʼ ἡμῶν ἔρημος, οἰκιστὴς δὲ ἐγένετο αὐτῆς Ναύπλιος Ποσειδῶνος λεγόμενος καὶ Ἀμυμώνης εἶναι. λείπεται δὲ καὶ τειχῶν ἔτι ἐρείπια, καὶ Ποσειδῶνος ἱερὸν καὶ λιμένες εἰσὶν ἐν Ναυπλίᾳ καὶ πηγὴ Κάναθος καλουμένη· ἐνταῦθα τὴν Ἥραν φασὶν Ἀργεῖοι κατὰ ἔτος λουμένην παρθένον γίνεσθαι.
Nauplia lies, as it seems to me, fifty stadia distant from Temenium. In our time it is deserted, but its founder is said to have been Nauplius, who was born from Poseidon and Amymone. Remains of walls still survive, and at Nauplia there is a sanctuary of Poseidon, as well as harbors and a spring called Canathus. Here, according to Argive tradition, Hera bathes each year and thus renews her virginity.
