Passage 8.9.2
καὶ τοῦ μὲν ἐπιμνησθησόμεθα καὶ ἐν τοῖς ἔπειτα, Μαντινεῦσι δέ ἐστι καὶ ἄλλα ἱερά, τὸ μὲν Σωτῆρος Διός, τὸ δὲ Ἐπιδώτου καλουμένου· ἐπιδιδόναι γὰρ δὴ ἀγαθὰ αὐτὸν ἀνθρώποις. ἔστι δὲ καὶ Διοσκούρων καὶ ἑτέρωθι Δήμητρος καὶ Κόρης ἱερόν· πῦρ δὲ ἐνταῦθα καίουσι, ποιούμενοι φροντίδα μὴ λάθῃ σφίσιν ἀποσβεσθέν. καὶ Ἥρας πρὸς τῷ θεάτρῳ ναὸν ἐθεασάμην·
Concerning this one, we shall speak again later. As for the Mantineans, they also have other sanctuaries, one dedicated to Zeus Soter (the Savior) and another to a god called Epidotes ("the Giver"), since indeed he bestows benefits upon men. There is also a sanctuary of the Dioscuri and elsewhere one of Demeter and the Maiden. Here they keep a perpetual fire burning, carefully ensuring that it never unintentionally goes out. Near the theater too, I saw a temple of Hera.
