In Christian demonology (Late Medieval- Early Modern European), Amduscias (also spelled Amdusias, Amdukias) is a demon with the title of Great Duke of Hell, commanding 29 legions of demons (some sources say 30). He appears as a human with the head of a unicorn, and claws in place of hands and feet, though can transform into a human if his conjurer wishes. Amduscias is accompanied by the sounds of trumpets when he arrives. He gives concerts even though no instruments may be around. Trees bend and bow to his will. Amduscias is 1 of 69 demons listed in the Pseudomonarchia Dæmonum and and 1 of 72 listed in the Ars Goetia (the first section of the Lesser Key of Solomon).
