In demonologyBalam is a great and powerful King (to some authors a Duke) of Hell, a terrible one, commanding over forty legions of demons. He gives perfect answers on things past, present and to come, speaking with a hoarse voice, and can also make men invisible and witty.
Balam is depicted three-headed, being one the head of a bull, other of a man, and the third of a ram, with the tail of a serpent and flaming eyes. He carries a hawk on his fist and rides a strong bear. Other representation is as a naked man riding a bear.
The demon barbu is not to be confused with Barbatos, said to be a Duke in Hades, although not a philosopher; nor with Barbas, who is interested in mechanics.
The demon thus characterized by a medieval writer is Belial (Beliar is the Greek equivalent of the Hebrew), the demon of lies.
