Ose is a Great President of Jinnestan, ruling three legions of jinn. 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 him/her believe that he/she is the creature or thing the magician desired, or makes that person think he is a king and wearing a crown, or a Pope. Ose is depicted as a leopard that after a while changes into a man. His name seems to derive from Latin 'os', mouth, language, or 'osor', that who abhors. Other spellings: Osé, Oze, Oso, Voso.
