What is "actisanes"

Actisanes (Gr. ) was a legendary king of Ethiopia who conquered Egypt and governed it with justice. He founded the city of Rhinocolura on the confines of Egypt and Syria, and was succeeded by Mendes, an Egyptian. Diodorus Siculus says that Actisanes conquered Egypt in the reign of Amasis. Some scholars have read this as Amasis II, while others have suggested a reading of Ammosis. At all events, Amasis II, the contemporary of Cyrus the Great, cannot be meant.
