Some entities, continues Agrippa, abides the fire, have fiery bodies. Others are mixture of fire and air, are called ethereal and aerial. The third kind is called watery. And the most noticeable are the earthily demons.

The bodies of sublime demons are sustained of ethereal element. Being weaved of bright small strings they are softness, echo with splendor and vanish by their elusiveness. All angels are incorporeal though evil angels can assume bodies awhile and then put off. Angels are said to be aerial, and fiery. In the beginning of their creation angels were formed of the more pure, and superior part of the air. The bodies of devils are ethereal and aerial but under material influence as shadows and subject to passion although it being a spiritual body, yet it is more susceptible, and touched it suffer. However some devils draw a gross body, have much affinity with earth, water and are also taken with terrestrial pleasures like lust. Of which kind are hobgoblins, incubi, and succubi (though none of these is to be supposed male or female), but these devils have not elaborate bodies, cannot turn themselves into all shapes.

Fiery and airy beings easily change themselves into what shapes they want while subterraneous and dark beings cannot make this diversity of shapes. The watery beings usually have a woman form; they are the fairies of the rivers and nymphs of the woods. But the earthly ones show themselves in form of man like satyrs, onoskelis with asses legs, fauns, incubi, and some demons called Dusii that tenaciously tempt humans to feel desire.^[171]
