In demonology Dantalion is a powerful Great Duke of Hell, and has thirty-six legions of demons under his command. He teaches all arts and sciences, and also declares the secret counsel of anyone, being that he knows the thoughts of all people and can change them at his will. He can also cause love and show the similitude of any person, show the same by means of a vision, and let them be in any part of the world they will.

He is depicted as a man with many appearances, which means the faces of all men and women.
