Bael is a ranked spirit in early modern magical catalogues. The Goetic figure should be distinguished from the wider use of the ancient title Baal.

Paimon is a royal spirit described in the Ars Goetia and related literature. Musical procession and the teaching of knowledge are important elements of his received image.
