The king of Egypt who was subject to the Roman Emperor Lucius. He was called upon to join Lucius in the war against Arthur. He led a force of soldiers at the battle of Soissons.
In Malory’s account, the “King of Egypt and Ethiopia” is killed at Soissons, but it is unclear if this is the same character.
