In demonology, Zagan is a Great King and President of Hell.
Zagan is a Great King and President of Hell who commands over thirty-three legions of demons.
Zagan makes men witty; he can also turn wine into water, water into wine, and blood into wine (according to Pseudomonarchia Daemonum blood into oil, oil into blood, and a fool into a wise man). Other of his powers is that of turning metals into coins that are made with that metal (i.e., gold into a gold coin, copper into a copper coin, etc.).
Zagan is depicted as a griffin-winged bull that turns into a man after a while. Other authors portray him as a bull-headed man with the wings of a griffin.

Pseudomonarchia daemonum - Johann Wier (1583)
