Buer is a spirit that appears in the 16th century grimoire Pseudomonarchia Daemonum and its derivatives, where he is described as a Great President of Hell, having fifty legions of demons under his command. 

He appears when the Sun is in Sagittarius. Buer teaches Natural and Moral Philosophy, Logic, and the virtues of all herbs and plants. 

He also heals all infirmities, especially of men, and gives good familiars.

He is depicted in the shape of Sagittarius, which is as a centaur with a bow and arrows. Additionally, Louis Le Breton created an illustration of Buer, later engraved by M.

Jarrault, depicting the demon as having the head of a lion and five goat legs surrounding his body to walk in every direction.

Although the etymology of his name is uncertain, curiously there was an ancient city named “Buer” (now Gelsenkirchen) in Westphalia, Germany.


11: Duke Gusion

Gusion is a strong Great Duke of Hell, and rules over forty legions of demons. He tells all past, present and future things, shows the meaning of all questions that are asked to him, reconciles friends, and gives honour and dignity.

He is depicted as a baboon or according to some, in the form of a Xenophile.

Other spellings: Gusoin, Gusoyn.
