Voso Medallion

This is a seal from the book "Lesser Key of Solomon".  According this text, the spirit Voso, is described thus

"The Fifty-seventh Spirit is Oso,
Ose, or Yoso. 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 301 Legions of Spirits, and this is
his Seal, etc"
