I’ll be covering the goetic spirit Balam or Balaam here; He is the 51st one mentioned in the Goetia, as follows:

” The Fifty-First Spirit is Balam or Balaam. He is a Terrible, Great, and Powerful King. He
appeareth with three Heads: the first is like that of a Bull; the second is like that of a Man; the third is like that of a Ram. He hath the Tail of a Serpent, and Flaming Eyes.
He rideth upon a furious Bear, and carrieth a Goshawk upon his Fist. He speaketh with a hoarse Voice, giving True Answers of Things Past, Present, and to Come. He maketh men to go Invisible, and also to be Witty “.

Balam is Saturnian (Capricorn, 24°- Universal) in nature and excels in making one intellectual and can help the operator become a world-renown writer or similar; all things of a higher educative nature (architect, lawyer etc.) are up for grabs. So only the witty part applies regarding His goetic description. 

In terms of appearance, He appears indeed as mentioned more or less, but that’s more for show- in reality, He appears as an angel dressed in white with black hair, very courteous and all & told me that He used to belong to the order of powers, and has another seal that He’ll give when being worked with.
