Passage 1.42.1
ἔστι δὲ καὶ ἄλλη Μεγαρεῦσιν ἀκρόπολις ἀπὸ Ἀλκάθου τὸ ὄνομα ἔχουσα· ἐς ταύτην τὴν ἀκρόπολιν ἀνιοῦσίν ἐστιν ἐν δεξιᾷ Μεγαρέως μνῆμα, ὃς κατὰ τὴν ἐπιστρατείαν τῶν Κρητῶν ξύμμαχός σφισιν ἦλθεν ἐξ Ὀγχηστοῦ. δείκνυται δὲ καὶ ἑστία θεῶν Προδομέων καλουμένων· θῦσαι δέ σφισιν Ἀλκάθουν λέγουσι πρῶτον, ὅτε τῆς οἰκοδομίας τοῦ τείχους ἔμελλεν ἄρχεσθαι.
The Megarians have another acropolis named from Alcathous. As you ascend to this acropolis, on your right is the tomb of Megareus, who came as an ally to them from Onchestus during the war against the Cretans. There is also shown here a hearth of gods called Prodomeis ("Builders Beforehand"), first sacrificed to, they say, by Alcathous, when he was about to begin the construction of the wall.
