The joint archaeological mission of the University of Dallas made huge discoveries in the area of Nabta 100 km west of Abu Simbel. The discoveries relate to prehistoric times, tools, clay vessels, and skeletons. The area of Nabta is one of the most important areas for archaeological excavation related to prehistoric times. It measures 5,000 square meters and includes the remains of stores, wells and houses. The mission also found tombs where in one of them there were 30 skeletons and some bracelets made of the teeth of animals and many clay vessels.
Most important is what is thought to be the first clock. It is shaped as a circle made of stones whose diameter is 4 meters. There are 6 stones near the center and arranged in two lines extending east and west. Time is measured by this clock through the shade of the stones in the center which falls on the stones of the circle.
Archaeologists found bulks of stones placed in correspondence with the positions of the stars in order to know the time of the different seasons especially the rainy ones. They also found a tomb of a cow which indicates the beginning of cow-worship identified later with the cow-goddess Hathor.
