Passage 7.17.5
τάδε μὲν οὕτω συμβάντα εὕρισκον· Ἀχαιοῖς δὲ ὅροι καὶ Ἠλείοις τῆς χώρας ποταμός τε Λάρισος καὶ Ἀθηνᾶς ἐπὶ τῷ ποταμῷ ναός ἐστι Λαρισαίας, καὶ Ἀχαιῶν πόλις Δύμη σταδίους ὅσον τε τριάκοντα ἀπέχει τοῦ Λαρίσου. ταύτην Φίλιππος ὁ Δημητρίου πολεμῶν μόνην τῶν Ἀχαϊκῶν ἔσχεν ὑπήκοον, καὶ ἐπὶ τῇ αἰτίᾳ ταύτῃ Σουλπίκιος, ἡγεμὼν καὶ οὗτος Ῥωμαίων, ἐπέτρεψε τῇ στρατιᾷ διαρπάσαι τὴν Δύμην· Αὔγουστος δὲ ὕστερον καὶ προσένειμεν αὐτὴν Πατρεῦσιν.
These events I found to have occurred as described above. Between the Eleians and the Achaians the boundary of their territories is the river Larisus, and by this river is situated a temple of Athena Larisaea. The Achaian city of Dyme lies about thirty stadia from the Larisus. During his war against the Achaians, Philip, son of Demetrius, made Dyme alone of all the Achaian cities subject to him; and for this reason Sulpicius, another general of the Romans, permitted his army to plunder Dyme. Later, Augustus bestowed this city upon the people of Patrae.
