DEMONS in the Ars Goetia
The demons' names are taken from the Ars Goetia, which differs in terms of number and ranking from the Pseudomonarchia Daemonum of Johann Weyer. As a result of multiple translations, there are multiple spellings for some of the names. 
 
Aamon (or Amon, Nahum) is a Marquis of Hell who governs forty infernal legions. He appears as a wolf with a serpent's tail who can breathe fire, or as a man with a raven's head, sometimes depicted with canine teeth. He tells of all things past and future. He procures feuds, and reconciles controversies between friends and foes.
