Question: who are the demon princes?
Answer: The Book of Abramelin, possibly written in the 14th or 15th century, lists four princes of the demons: Lucifer, Leviathan, Satan and Belial. There are also eight sub-princes: Astaroth, Maggot, Asmodee, Beelzebub, Oriens, Paimon, Ariton (Egin) and Amaymon. Under the rule of these there are many lesser demons.
