Osé

The Fifty-seventh Spirit is Oso, Osé, or Voso. He is a Great President, and appeareth like a Leopard at the first, but after a little time he putteth on the Shape of a Man. His Office is to make one cunning in the Liberal Sciences, and to give True Answers of Divine and Secret Things; also to change a Man into any Shape that the Exorcist pleaseth, so that he that is so changed will not think any other thing than that he is in verity that Creature or Thing he is changed into. He governeth 3026 Legions of Spirits, and this is his Seal, etc.
