legends about Nilotes

Nilotes or Nilotic people is a group of tribes which originate from valleys of Nile. Many Nilotic tribes have overcome huge distances, moving from place to place. All Nilotes have some common features: they mostly are cattlemen, they are tall and thin, they have faces with less negroid features. But this is just anthropological description. For me, the most valuable is their richest culture of ceremonies and traditions.
