Passage 7.25.6
τῷ ἐν Τίρυνθι ὑπὸ τῶν Κυκλώπων καλουμένων, κατὰ ἀνάγκην δὲ ἐκλείπουσι Μυκηναῖοι τὴν πόλιν ἐπιλειπόντων σφᾶς τῶν σιτίων, καὶ ἄλλοι μέν τινες ἐς Κλεωνὰς ἀποχωροῦσιν ἐξ αὐτῶν, τοῦ δήμου δὲ πλέον μὲν ἥμισυ ἐς Μακεδονίαν καταφεύγουσι παρὰ Ἀλέξανδρον, ᾧ Μαρδόνιος ὁ Γωβρύου τὴν ἀγγελίαν ἐπίστευσεν ἐς Ἀθηναίους ἀπαγγεῖλαι· ὁ δὲ ἄλλος δῆμος ἀφίκοντο ἐς τὴν Κερύνειαν, καὶ δυνατωτέρα τε ἡ Κερύνεια οἰκητόρων πλήθει καὶ ἐς τὸ ἔπειτα ἐγένετο ἐπιφανεστέρα διὰ τὴν συνοίκησιν τῶν Μυκηναίων.
Because they were compelled by necessity, when provisions failed, the Mycenaeans abandoned the city built in Tiryns by those called Cyclopes. Some withdrew to Cleonae, but more than half of the populace sought refuge in Macedonia with Alexander, whom Mardonius, son of Gobryas, had trusted to carry his message to the Athenians. The rest of the people came to Ceryneia, and through this cohabitation with the Mycenaeans, Ceryneia thereafter grew in both population and importance.
