Marbas

The fifth Spirit is Marbas. He is a Great President, and appeareth at first in the form of a Great Lion, but afterwards, at the request of the Master, he putteth on Human Shape. He answereth truly of things Hidden or Secret. He causeth Diseases and cureth them. Again, he giveth great Wisdom and Knowledge in Mechanical Arts; and can change men into other shapes. He governeth 36 Legions of Spirits. And his Seal is this, which is to be worn as aforesaid.

[According to the Ars Goetia, in 'The Lesser Key of Solomon' which contains descriptions of the seventy-two demons evoked and confined by Solomon.]
