In demonology, Bune is a Great Duke of Hell.
Also called Bime or Bimé
A mighty and strong Great Duke of Hell with thirty legions of demons under his command.
Bune is depicted as a three-headed dragon, being his heads like those of a dog, a griffin, and a man (although according to some grimoires he has two heads like a dragon and the third like a man). He speaks with a comely high voice.
Bune changes the place of the dead and makes them demons that are under his power to gather together upon those sepulchres. He makes men eloquent and wise, and gives true answers to their demands and also richness.
Bune is a great and a strong Duke, he appeareth as a dragon with three heads, the third whereof is like to a man; he speaketh with a divine voice, he maketh the dead to change their place, and divels to assemble upon the sepulchers of the dead: he greatlie inricheth a man, and maketh him eloquent and wise, answering trulie to all demands, and thirtie legions obeie him.
