In Christian demonology, Amdusias (also Amduscias, Amdukias, Ambduscias) is a Great Duke of Hell.

Amdusias, from Collin de Plancy's Dictionnaire Infernal.


Amdusias is depicted as a human with claws instead of hands and feet, the head of a unicorn, and a trumpet to symbolise his powerful voice. According to other sources, this demon is depicted as a unicorn, and changes into a man under the request of the conjurer.


Amduscias has thirty legions of demons under his command (twenty-nine according to other authors) and has the rank of Great Duke of Hell.


Amdusias is associated with thunder and it has been said that his voice is heard during storms. In other sources, he is accompanied by the sound of trumpets when he comes and will give concerts if commanded , but while all types of musical instruments can be heard they can't be seen. He can make trees bend at will.


Amduscias a great and a strong duke, he commeth foorth as an unicorne, when he standeth before his maister in humane shape, being commanded, he easilie bringeth to passe, that trumpets and all musicall instruments may be heard and not seene, and also that trees shall bend and incline, according to the conjurors will, he is excellent among familiars, and hath nine and twentie legions. Pseudomonarchia daemonum - Johann Wier (1583)
