Passage 1.43.2
ἐν δὲ τῷ πρυτανείῳ τεθάφθαι μὲν Εὔιππον Μεγαρέως παῖδα, τεθάφθαι δὲ τὸν Ἀλκάθου λέγουσιν Ἰσχέπολιν. ἔστι δὲ τοῦ πρυτανείου πέτρα πλησίον· Ἀνακληθρίδα τὴν πέτραν ὀνομάζουσιν, ὡς Δημήτηρ, εἴ τῳ πιστά, ὅτε τὴν παῖδα ἐπλανᾶτο ζητοῦσα, καὶ ἐνταῦθα ἀνεκάλεσεν αὐτήν. ἐοικότα δὲ τῷ λόγῳ δρῶσιν ἐς ἡμᾶς ἔτι αἱ Μεγαρέων γυναῖκες.
They say that in the Prytaneion Eupippos son of Megareus is buried, and also Ischepolis, the son of Alcathous, is buried there. Near the Prytaneion there is a rock called Anaclethris ("Recall-rock"), because, if the story is trustworthy, Demeter here called back her daughter when she wandered, searching for her. Even to our time, the women of Megara perform rites appropriate to this tradition.
