In demonology, Ose (Pronounced /ˈɒze/), is a Great President of Hell, ruling three legions of demons (thirty to other authors, and Pseudomonarchia Daemonum gives no number of legions). He makes men wise in all liberal sciences and gives true answers concerning divine and secret things; he also brings insanity to any person the conjurer wishes, making them believe that they are king and wearing a crown, or a Pope. However, his spells only last 1 hour at a time.
