Lesser Key of Solomon
The Thirty-ninth Spirit is Malphas. He appeareth at first like a Crow, but after he will put on Human Shape at the request of the Exorcist, and speak with a hoarse Voice. He is a Mighty President and Powerful. He can build Houses and High Towers, and can bring to thy Knowledge Enemies' Desires and Thoughts, and that which they have done. He giveth good Familiars. If thou makest a Sacrifice unto him he will receive it kindly and willingly, but he will deceive him that doth it. He governeth 40 Legions of Spirits.
