Sheep in Ancient Egypt Egyptian Name: Ser Hieroglyphics: The ancient Egyptians referred to both goats and sheep by a single term, "small cattle," thereby ignoring their considerable differences. Sheep were not common in ancient Egypt, as wool was not of great economic importance to the Egyptians - they preferred the less hot and itchy linen and later, the lighter cotton to wool. Sheep were kept for their meat, milk, and skins, and the flocks were used to tread seed into the fields after sowing. Sheep tail fat - alya - was used in cooking. The first sheep entered Egypt via Sinai, and were present in ancient Egyptian society between eight and seven thousand years ago. Ancient Egypt possessed in succession two different species of domesticated sheep, both descended from the Iranian Red Sheep. o The older breed, (ovis longipes), had horns jutting out o The newer fat tailed sheep, (ovis platyra), which was introduced during the Middle Kingdom, had horns curled close to the head on either side. Both kinds were most commonly domesticated sheep utilized on the reliefs of early pharaonic tombs. Wikipedia Ovis longipes palaeoaegyptiacus Ovis platyra sheep 6 Barbary sheep Barbary sheep once resided across North Africa‟s mountainous areas, but the indigenous population is now confined to small, mostly isolated pockets. Barbary sheep used to cover nearly all of Egypt except Sinai, but since the mid-1900s their habitat has been confined mainly to the southwest near the Libyan border and the southeast near the Sudanese border. Barbary sheep have large curved horns and are sandy or reddish brown colored. Aoudad or Barbary Sheep (Ammotragus lervia), Wildlife Facts The three main breeds of sheep in Egypt are Rahmani, Osseimi and Barki: Rahmani sheep is the largest breed, easily identifiable by its red wool and small ears. Origin in Northern Syria and Southern Turkey. The breed was first introduced into Egypt in the 19" Century and is named after Rahmania, a village in Beheira governorate in the north of the Nile Delta. Population is about 250,000 head in the North and Middle of the Nile Delta.
