god is represented driving a four-wheeled chariot, in contrast to the Assyrian war-chariots which were two-wheeled; the chariot is drawn by an animal of uncertain character, which Ward originally regarded as a horse, but in view of a representation of a bull drawing a chariot, found on an early Assyrian seal which he dates about 2000 B.C., it is clear that the bull was used to draw chariots in early times, and Ward accordingly regards the ambiguous animal alluded to, as also a bull. The Sumerian name for the horse was “the ass of the mountains,” an indication that the animal was first known to them in its wild state: we find it figured on one of Nebuchadnezzar I’s boundary stone (_circ._ 1120 B.C.), but it was certainly known in the valley much earlier. The Hyksos, or shepherd-kings from Asia introduced the horse into Egypt about 1700 B.C., while mention is made of horses in a letter from Burraburiash the king of Babylon to Amenḥetep, king of Egypt about 1400 B.C. An extremely early fragment from Nippur (cf. Fig. 25, E) published by Hilprecht and quoted and reproduced by Ward,[7] shows us a horned animal dragging a plough, which Ward thinks may be a gazelle or an antelope; if the latter be the case, we may perhaps infer that an animal of that species was used for draft purposes before the bull, and certainly before the horse. However that may be, in later days the horse seems to have been reserved for the battle-field and the chase. The Assyrian soldiers both rode them and harnessed them to their war-chariots, and it is worth noticing how much more successful the Assyrian sculptors were in their representations of the horse than the Egyptians. The horses on the bas-reliefs apparently belong to a smaller, shorter and more thick-set breed than Arabs, and the breed is still supposed to be extant in Kurdistan. The Assyrians do not seem to have been in the habit of endowing the horse with wings or with a human head, as they sometimes did the bull and the lion, though some of the Pehlevi[8] seals and rings of later days (A.D. 226-632) show figures of winged horses.
