Κορόπη, πόλις Θεσσαλίας. ὁ πολίτης Κοροπαῖος. Νίκανδρος ἐν Θηριακοῖς “ᾗ ἐν Ἀπόλλων μαντείας Κοροπαῖος ἐθήκατο καὶ θέμιν ἀνδρῶν”. οἱ δὲ ὑπομνηματίσαντες αὐτὸν Θέων καὶ Πλούταρχος καὶ Δημήτριος ὁ Φαληρεύς φασι “Νίκανδρος Ὀροπαῖος καὶ Κοροπαῖος Ἀπόλλων. ἀγνοεῖ δ´ ὅτι Ἀμφιαράου ἱερόν, [οὐκ] Ἀπόλλωνός ἐστι. λέγεται δὲ κατ´ ἔλλειψιν τοῦ « κ » Ὀροπαῖος [Κορόπη]. Κορόπη δὲ Θεσσαλίας πόλις. βέλτιον δ´ ὑπονοεῖν ὅτι ἡμάρτηται. καὶ γράφεται Ὀροπαῖος. Ὀρόπη γὰρ πόλις Εὐβοίας, ὅπου Ἀπόλλωνος διασημότατον ἱερόν”.
Koropē, a city of Thessaly. The citizen is called Koropaios. Nicander in the Thēriaka: “where Apollo the Koropaios established oracles and an ordinance for men.” But those who wrote commentaries on him—Theon and Plutarch and Demetrius of Phalerum—say: “Nicander [means] Apollo of Oropos and of Koropē. He does not know that it is a sanctuary of Amphiaraus, not of Apollo. And ‘Oropaios’ is said by omission of the kappa (Koropē).” Koropē, however, is a city of Thessaly. It is better to suppose that he has made a mistake; and one also writes Oropaios. For Oropē is a city of Euboea, where there is a very famous sanctuary of Apollo.”
