to basic, traditional norms.Predynastic EgyptEgyptian history is usually divided into periods roughly corresponding to the 30 dynasties of kings listed by Manetho, an Egyptian chronicler of the 3d century BC. The period before c.3100 BC, a time for which no written records exist, is called the Predynastic era. Well before 5000 BC many communities of Paleolithic hunters and gatherers lived in the Nile valley and across savanna lands stretching far to the east and west. As rainfall decreased, especially after 4000 BC, the western lands became arid deserts and human settlement was confined to the valley and its fringes. However, here exotic fauna such as elephants and giraffes persisted as late as 2300 BC before finally retreating southward.Annually inundated, and with natural irrigation basins that retained floodwaters, the Nile valley was an ideal setting for Mesolithic economies with incipient agriculture to evolve into Neolithic ones based on sedentary agriculture, with domesticated crops and animals. The process is hard to follow in Egypt because major Predynastic sites, on the floodplain, are inaccessible or destroyed and most data come from peripheral settlements and low-desert cemeteries. In northern Egypt, however, the development of Neolithic life can be traced at Merimdeh and in the Fayum (5000-4000 BC); there and elsewhere in the north the pervasive northern culture emerged, characterized by monochrome pottery using incised and applied decoration. The earliest Neolithic phases of southern Egypt are not yet identified, but two cultures existed there by c.4000 BC: the Tasian, influenced by the north, and the Badarian, which originated in the eastern desert. The former evolved into phases labeled Nakada I (Amratian) and II (Gerzean), representing a material culture very different from that of the north. In the south, among other differences, pottery is more varied in fabric, often has a black top, and favors painted deco...
