Caspiel is a demon among the thirdy-one Aerial Spirits of Solomon. Caspiel is the chief emperor of the south, who rules over 200 great dukes, 400 lesser dukes, and 1,000,200,000,000 ministering spirits. His twelve most important dukes are Ursiel, Chariet, Maras, Femot, Dudarion, Camory, Larmot, Aridiel, Geriel, Ambri, Carnor, and Oriel. Each of the twelve dukes is attended by 2,660 lesser dukes. All of the dukes are stubborn and churlish, but many attend Caspiel when he appears.
