Cambyses was the first ruler of the Twenty-sixth Dynasty. He was the ruler of Persia and treated the last ruler of the Twenty-fifth Dynasty, Psammetichus III (Psamtik III) with some consideration. Psammetichus then tried to revolt and Cambyses caused him to be killed. There is an inscription on a statue that tells of Cambyses going to Sais to worship Neith and restore the revenues and festivals of the temple. But according to Herodotus, Cambyses did many reprehensible things against Egyptian religion and customs and eventually went mad.
