Passage 4.31.2
καὶ ὁ μὲν τούτων ἕνεκα Μεσσηνίοις καὶ τῶν ἄλλων τῶν ἀντιταξαμένων τοῖς μὲν αὐτῶν ἔλαττον, τοῖς δὲ καὶ ἐς πλέον ἐπεξῆλθε· Θουριᾶται δὲ ἐκ τῆς πόλεως ἐν μετεώρῳ τὸ ἀρχαῖον οἰκουμένης ἐς τὸ πεδίον κατελθόντες οἰκοῦσιν. οὐ μὴν παντάπασί γε οὐδὲ τὴν ἄνω πόλιν ἐκλελοίπασιν, ἀλλὰ καὶ τείχους ἐρείπια καὶ ἱερόν ἐστιν αὐτόθι ὀνομαζόμενον θεοῦ Συρίας· τὴν δὲ ἐν τῷ πεδίῳ πόλιν ποταμὸς καλούμενος Ἄρις παρέξεισιν.
For these reasons, he dealt harshly with the Messenians, and with the others who had opposed him, some less severely, others even more so. As for the people of Thouria, having descended from their ancient settlement located on high ground, they now dwell in the plain; yet they have not completely abandoned the upper city. Still remaining there are ruins of a wall, and a sanctuary dedicated to the goddess named the Syrian Goddess. Near the city in the plain flows a river named Aris.
