Italian Roman Catholic priest and the senior exorcist of the Diocese of Rome.
Amorth authored two books specifically on exorcism. The publications marked a defining moment in literary history, being the first public documents to treat this subject. The two books An Exorcist Tells His Story and An Exorcist: More Stories are not official Roman Catholic documents, rather personal accounts of his office as Exorcist. The books use witness accounts and personal experience as evidence.
