Ose

Historical Background
In Christian demonology (Late Medieval- Early Modern European), Ose (also spelled Oze, Oso,Osé, Voso) is a demon with the rank and title of Great President of Hell, commanding 3 legions of demons (other authors say 30 or do not give a number). He is depicted as a leopard that can transform into a man. He can make his conjurers wise in all the liberal sciences and unlike most demons, gives honest answers, but that guarantee only applies to secrets or divine matters. Ose can also inflict insanity on any person his conjurer wants (such as making that person think they were some animal or object, or even think they were royalty or a pope). The Coeurl is the closest to Ose's form. Ose seems to derive from the Latin word "os", meaning "mouth" or "language", or perhaps "osor", which means "that who abhors". Ose is 1 of 69 demons listed in the Pseudomonarchia Dæmonum and 1 of 72 listed in the Ars Goetia (the first section of the Lesser Key of Solomon).
