Gurzil or Agurzil was a war deity of the ancient Berbers.
In Berber mythology, Gurzil was a bull-shaped war god who became identified with the son of Amun (Ammon). He was taken by the Berbers to their battles against the Romans.
In the 6th century, Corippus mentioned that Iarna -- chief of the Berber tribe known as the Laguatans (or Luwata as they were later known to the Arabs) -- took his god "Gurzil" into battle against the Byzantines. Larna was a Berber ruler and a high priest of Gurzil. After the Berbers where defeated he fled with the "sacred image" of Gurzil, but was caught and killed and the image destroyed. Gurzil was later taken by the Berber queen Dihya (Kahina) into her battles against the Muslim Invasion.
There was among the ruins of Ghirza in Libya a temple, which may have been dedicated to Gurzil, and the name of the town itself may even be related to his name.
