Oreus

Oreus, known before the 5th century BC as Histiaea, was an ancient town on the north coast of Euboea in Greece, situated on the river Callas at the foot of Mount Telethrium. One of the most ancient of the Euboean cities, it appears in the Catalogue of Ships in Homer Iliad and was an important city in classical antiquity due to its strategic position at the entrance of the North Euboean Gulf.
