Conope or Konope and later, Arsinoe (Ἀρσινόη) or Arsinoia, was a city of ancient Aetolia, in Greece, near the eastern bank of the Achelous River, and 20 stadia from the ford of this river (approximately 1.9 to 2.6 miles. It was only a village, until it was enlarged by Arsinoe, the wife and sister of Ptolemy Philadelphus. Polybius, in his history of the Social War, calls it Conope, though elsewhere he calls it Arsinoe or Arsinoia. It is mentioned by Cicero under the name of Arsinoe. Near this town the river Cyathus flowed into the Achelous from the lake Hyria, which is also called Conope by Antoninus Liberalis.
