Classification of demons

There have been various attempts at the classification of demons within the contexts of classical mythology, demonology, occultism, and Renaissance magic. These classifications may be for purposes of traditional medicine, exorcisms, ceremonial magic, witch-hunts, lessons in morality, folklore, religious ritual, or combinations thereof. Classifications might be according to astrological connections, elemental forms, noble titles, or parallels to the angelic hierarchy; or by association with particular sins, diseases, and other calamities; or by what angel or saint opposes them.

Many of the authors of such classifications identified as Christian, though Christians authors are not the only ones who have written on the subject.
