Relatively little wool has been found in Egyptian tombs, and finds are mainly late in date. Nevertheless, there have been incidental finds from all periods, even prehistoric times. A skeleton from the 1st Dynasty, for example, was found wrapped in a wool blanket. Balls of wool have been found at El-`Amarna, each consisting of hundreds of metres of spun wool. There were always a lot of sheep in Egypt, so it is unlikely that wool was never used as a material, especially since protective clothing would have been needed in the winter. Herodotus, who visited Egypt in the fifth century BC, does indeed note that woollen cloaks were worn over linen clothes. He adds that it was forbidden to take wool into a temple or to bury it with the dead, because the material was ritually impure. Even the sparse archaeological material we have indicates that the Greek historian must have been wrong about this.
