The origin of such a notion is to be sought, perhaps, so far as Mesopotamia is concerned, in a wise hygiene and in the rapid changes of an uncertain climate. The difference between the extremes of summer and winter temperature is far greater than in Egypt or on the Ionian coasts, and precautions had to be taken at one time against a scorching sun, at another against the cold of the nights. However this may have been, it is certain that these people, although they lived in a hot country, went about in a costume that covered their bodies as completely as that of modern Europe. It consisted of a long tunic, a _tunica talaria_ (?) as the Romans would call it, and a mantle. The tunic left nothing exposed but the head and neck, the forearms, and the feet and ankles. It must have been of linen or hempen cloth;[107] when worn by a rich man it was embroidered and decorated about the foot with a sort of gimp fringe. The tunics of the poor were short and plain, often coming hardly lower than the knee. They were also looser and better fitted to work in; but they are never wanting altogether, even to the men of the _corvée_, the slaves and prisoners of war whom we see employed in the construction of the royal buildings (Vol. I. Figs. 151 and 152). Women were dressed in chemises coming down to their feet (Vol. I. Fig. 30), resembling the long robe of coarse blue cotton which still forms the only garment of the peasant women of Egypt and Syria. Sometimes we find a sort of cape thrown over the tunic (Vol. I. Fig. 31, and below, Fig. 44). [Illustration: FIG. 43.--Merodach or Marduk-idin-akhi. From a basalt stele in the British Museum. Height 24 inches.

In the painting at Beni-Hassan which shows us the arrival in Egypt of a band of Asiatic emigrants,[108] it leaves one shoulder and both arms uncovered, and forms a kind of frock round the body, which it entirely conceals. In the old Chaldæan statues from Sirtella the arrangement is more graceful (see Plate VI.); the piece of cloth is folded double and carried obliquely round the body so as to cover the left arm and shoulder and leave the right bare. The end is simply passed under the first fold, by which it is tightly held.[109] There is no trace of a tunic. In Assyria the mantle was variously arranged. It always left one shoulder free, which was covered, however, by the tunic. As a rule it reached to the feet (Vol. I. Fig. 22), but sometimes it was so contrived as to leave one leg exposed from the knee downwards. The robes of Sargon praying before the sacred tree are thus arranged (Fig. 45).
