The Demon Caspiel is a Demon among the 31 Aerial Spirits of Solomon.A great and chief emperor named in the Ars Theurgia. Caspiel is one of a number of Demons associated with the points of the compass. His dominion is the south. He has a vast array of Demons who serve under him, including two hudred great dukes and four hundred lesser dukes and 1,000,200,000,000 ministering spirits. The dukes who serve beneath him are described as stubborn and churlish. Caspiel has an airy nature. Consequently, if he manifests, it is often through images in a glass or in a specially prepared scrying crystal. In Dr. Rudd’s Treatise on Angel Magic, Caspiel is also identified as the chief Demon ruling over the south. He also appears in the Steganographia of Johannes Trithemius.
His 12 most important dukes are :
Each of the 12 dukes is attended by 2,660 lesser dukes. All of the dukes are stubborn and churlish, but many attend Caspiel when he appears.
