The War of Vesosis and Tanausis is described in Jordanes' Getica, a controversial 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.[1]
According to Arne Søby Christensen Jordanes assumed that the Scythians were the Goths and the women of the Goths Amazons. The war seems to be a retelling of an alleged war between the Scythians and Egyptians told by Orosius with Jordanes recasting a Scythian king as a king of the Goths.[2]
Some historians have said that the War of Vesosis and Tanausis may not have happened and is combination of transcription errors or fantasy.[3]
