The coffin-makers were large consumers of wood. Some mummy cases were of that material, others of a very thick board made up of many layers of linen glued together with such skill and firmness that the resulting substance had all the hardness and resonance of wood. Cases of both kinds were covered with a thin coat of plaster, varnished, and decorated with designs in colour. The thickness of the plaster coat may be easily seen in the numerous cracks which these coffins display. All the decorative motives which we find traced by the brush or engraved by the chisel upon the walls of buildings and upon works in terra-cotta, in metal, and in wood, must have been repeated upon the woven stuffs of the country, and upon those needle embroideries with which they were ornamented. There is nothing in which the superiority of Egyptian manufactures is better shown than in linen cloth. Linen has been recovered from the tombs which is as fine as the best Indian muslin. Some has been found which feels like silk to the touch, and equals the best French _batiste_ in the perfection of its weaving. We know from the bas-reliefs and paintings that some Egyptian stuffs had the transparency of gauze. Body-linen was usually of a dazzling white, but in some instances it was dyed red, and in others it had borders made up of several bands of red and indigo blue. The designs were either woven in the stuff or applied to it by a process which gave effects not unlike those of our printed cottons. Golden threads were introduced into specially fine tissues. But the great excellence of Egypt in such matters as these was in her needle embroidery. Even during the epoch of Roman supremacy her productions of that kind were eagerly sought after.[400] [400] MARTIAL, _Epigrammata_, xiv. 150. LUCAN, X. v. 141.

During the Middle Empire she opened her gates to some extent to certain tribes of Semites and Kushites, who dwelt close to her frontier. After her conquest by the Hyksos, and the establishment, some centuries later, of her own supremacy in Syria, she never ceased to hold intercourse with her neighbours.
