Stephanos of Byzantium - Ethnika
Korope, a city in Thessaly. A citizen is a 'Koropaios'. Nikandros in his Theriaka: 'wherein Apollo Koropaios established oracles and the judgement of men'. Those who wrote commentaries on him, Theon, Plutarch, and Demetrios of Phaleron, say: 'Nikandros has Oropaios and Apollo Koropaios. But he is unaware that it is a sanctuary of Amphiaraos, [not] of Apollo. It is called Oropaios by omission of the letter κ [Korope]. Korope, however, is a city in Thessaly. It is better to suppose that an error has been made; and it is written Oropaios. For Orope is a city of Euboia, where there is a very famous sanctuary of Apollo'.
