Passage 7.18.8
Πατρεῦσι δὲ ἐν ἄκρᾳ τῇ πόλει Λαφρίας ἱερόν ἐστιν Ἀρτέμιδος· ξενικὸν μὲν τῇ θεῷ τὸ ὄνομα, ἐσηγμένον δὲ ἑτέρωθεν καὶ τὸ ἄγαλμα. Καλυδῶνος γὰρ καὶ Αἰτωλίας τῆς ἄλλης ὑπὸ Αὐγούστου βασιλέως ἐρημωθείσης διὰ τὸ τὴν ἐς τὴν Νικόπολιν τὴν ὑπὲρ τοῦ Ἀκτίου συνοικίζεσθαι καὶ τὸ Αἰτωλικόν, οὕτω τὸ ἄγαλμα τῆς Λαφρίας οἱ Πατρεῖς ἔσχον.
The Patreans have, at the highest point of their city, a sanctuary of Artemis Laphria. The goddess's epithet is foreign, and her image was also brought in from elsewhere. For when Calydon and the rest of Aetolia were made desolate by Emperor Augustus, who transferred their inhabitants to Nicopolis, the city he founded in commemoration of his victory at Actium, the Patreans came into possession of the image of Laphria in this manner.
