Demonology is the science or doctrine concerned with the study of demons. It can comprise such features as a classification of their hierachy, of theior powers and limitations, attributes, multiple names and derivations. It has also come to mean a branch of magic that deals with malaevolent spirits.

The word itself derives from the Greek daimon, meaning simply a supernatural spirit or power of an inferior sort, i.e., not a god. In the Christian tradition, there was only one category of supernatural beings inferior to God, namely the angels, who were divided between those who joined in Lucifer's rebellion (a third of the heavenly host, according to the Book of Revelation) and were condemned to Hell, and those who remained loyal to their Creator and stayed in Heaven. Thus “demon'' came to mean “fallen angel, an inhabitant of Hell”.

The relationship of demonology to witchraft was crucial. By addressing the devil, or by supplications to his demons, witches were admitting to their power and thus they were therefore committing heresy.
