MAGNO´POLIS(Μαγνόπολις), a town in Pontus, at the confluence of the rivers Lycus and Iris, was founded by Mithridates Eupator, who called it Eupatoria; but it was completed by Pompey the Great, who changed its name into Magnopolis (Strab. 12. p. 556). The town seems to have fallen into decay at tan early period, as it is not mentioned by any late writer. Appian ( Mithrid. 78, 115) speaks of it under both names, Eupatoria and Magnopolis, and Strabo in one passage (12. p. 560) speaks of it under the name of Megalopolis. Ruins of the place are said to exist some miles to the west of Sonnisa, at a place called Boghaz Hissan Kaleh. (Hamilton, Researches, 1. p. 340.)
