"He didn't look much like a human anymore. His head was that of a huge black horse, or a unicorn, but it was nasty. The horn was long as I am, it stuck out forever! And it was drippy and twisted, moving up and down like it was covered in little skinny snakes. He pretty much doubled in size, and even though he still had his normal body, it was bigger. Way bigger. All covered in a thick hair and he had a tail and when he walked everything shook, like tiny earthquakes."
When I first read this story of a monster summoned with a small idol, I thought of the demon Amduscias:
"The Sixty-seventh Spirit is Amdusias, or Amdukias. He is a Duke Great and Strong, appearing at first like a Unicorn, but at the request of the Exorcist he standeth before him in Human Shape, causing Trumpets, and all manner of Musical Instruments to be heard, but not soon or immediately. Also he can cause Trees to bend and incline according to the Exorcist’s Will. He giveth Excellent Familiars. He governeth 29 Legions of Spirits. And his Seal is this, etc." -S.L. MacGregor Mathers, Goetia"Amduscias a great and a strong duke, he commeth foorth as an unicorne, when he standeth before his maister in humane shape, being commanded, he easilie bringeth to passe, that trumpets and all musicall instruments may be heard and not seene, and also that trees shall bend and incline, according to the conjurors will, he is excellent among familiars, and hath nine and twentie legions."

Philip's demon has horse feet in the story but otherwise they're pretty similar!
Don't forget this Friday I'll be selling Harboring Monsters with one of the original drawings featured in the book!
