Passage 8.12.2
ἐς Μεθύδριον δὲ πόλιν μὲν οὐκέτι, κώμην δὲ ἐς τὸ Μεγαλοπολιτικὸν συντελοῦσαν, ἐς τοῦτό ἐστι τὸ Μεθύδριον ἐκ Μαντινείας ὁδός. προελθόντι δὲ σταδίους τριάκοντα πεδίον τε ὀνομαζόμενον Ἀλκιμέδων καὶ ὑπὲρ τοῦ πεδίου τὸ ὄρος ἐστὶν ἡ Ὀστρακίνα, ἐν δὲ αὐτῷ σπήλαιον, ἔνθα ᾤκησεν Ἀλκιμέδων, ἀνὴρ τῶν καλουμένων ἡρώων.
From Mantineia there is a road to Methydrium—a place that is no longer a city, but now merely a village incorporated into the territory of Megalopolis. Thirty stades further along, there is a plain called Alcimedon, and above this plain rises Mount Ostrakina. On the mountain is a cave, where Alcimedon, one of those called heroes, dwelt.
