The War of Vesosis and Tanausis is described in Jordanes' semi-historical account of the Goths as happening in remote antiquity when Vesosis, king of the Egyptians, made war against them. Their king at that time was Tanausis.
In a battle at the river Phasis in Colchis (modern Georgia), Tanausis, king of the Goths, met Vesosis, king of the Egyptians, and there inflicted a severe defeat upon him, pursuing him even to Egypt.
