Sais, known as Zau in ancient Egyptian and today as Sa el-Hagar, is located in Egypt's Delta. It was the county's capital during the 26th Dynasty late in Egypt's history and was at various other times an important center. The city is known from the very beginning of Egyptian history from wooden labels associated with King Aha. It was probably always the capital of the 4th Lower Egyptian nome, which, until the 12th Dynasty, also incorporated what was to become the 4th nome. However, the city really came into a prominent position towards the end of the 8th century BC when Tefnakhte and Bocchoris (24th Dynasty) rivaled the Nubian kings of the 25th Dynasty. It was also a major center for the worship of the Goddess Neith.
