OROPUS  , a

Greek seaport, on the Euripus, in the district Hetpaiail, opposite Eretria . It was a border city between Boeotia and Attica, and its possession was a continual cause of dispute between the two countries; but at last it came into the final possession of Athens, and is always alluded to under the Roman empire as an Attic town . The actual harbour, which was called Delphinium, was at the mouth of the Asopus, about a mile north of the city . A village still called Oropo occupies the site of the ancient town . The famous oracle of Amphiaraus was situated in the territory of Oropus, 12 stadia from the city . The site has been excavated by the Greek Archaeological Society; it contained a temple, a sacred spring, into which coins were thrown by worshippers, altars and porticoes, and a small theatre, of which the proscenium is well pre-served . Worshippers used to consult the oracle of Amphiaraus by sleeping on the skin of a slaughtered ram within the sacred building .
