Tomb of Ti, Saqqara, Egypt, 1995Photograph by Kenneth GarrettA wall relief from the fifth-century Tomb of Ti in Saqqara, Egypt, depicts kneeling scribes counting grains of wheat, and, above them, bakers mixing vessels of dough. Hieroglyphs, or picture symbols, were probably developed to add detailed information, such as time, place, and identity, to existing pictorial representations.
