Candido Amantini was what type of priest, able to cast out demons?
Exorcist In some religions, an exorcist is a person who is believed to be able to cast out the devil or other demons. A priest, a nun, a monk, a healer, a shaman or other specially prepared or instructed person can be an exorcist. An exorcist is a person who performs the ridding of demons or other supernatural beings who are alleged to have possessed a person, or (sometimes) a building or even an object.
Natural magic Natural magic (also called low magic) in the context of Renaissance magic is that part of the occult which deals with natural forces directly, as opposed to ceremonial magic, in particular goety and theurgy, which deals with the summoning of spirits. Heinrich Cornelius Agrippa so uses the term in his 1526 "de vanitate".
