DEMONIALITY or Incubi and Succubi

First written in the 17th century but published centuries later, Father Ludovico Maria Sinistrari’s Demoniality is one of the most infamous and unsettling works of demonology. This rare treatise explores the terrifying reality of incubi and succubi—demonic beings said to seduce, torment, and enslave mankind through forbidden unions.

Sinistrari, a Franciscan theologian, approaches the subject with chilling seriousness, presenting cases, testimonies, and theological arguments that affirm the existence of these spirits of lust and corruption. More than superstition, his work is a blend of moral theology, canon law, and occult testimony, written to warn believers of the dangers of demonic temptation that reaches even into the most intimate aspects of life.

Part theology, part forbidden history, Demoniality remains one of the most controversial and disturbing texts ever written on demonology—a book that peers into humanity’s darkest fears and the shadowy boundaries between spirit and flesh.
