The signature image of much of Arabian art is Bos primigenius/taurus. The artist emphasizes its long horns, and mottled body. Such depictions are known from southern Syria, western Iraq, eastern Jordan, throughout western Saudi Arabia and as far south as central South Arabia (Yemen and Oman). Opinions differ as to whether the animals were hunted for game or constituted domestic herds. Parallels to Sahara and the Horn of Africa art suggest an emphasis on domesticated herds. Osteological specimens from Jordan, Yemen, eastern Saudi Arabia, the Emirates and Oman suggest that domesticated cattle were well known to the local inhabitants by the late sixth millennium B.C.
