This volume contains an 1875 English translation of Father Sinistrari of Ameno's rare book on demonology "Demoniality, or Incubi and Succubi". It was published from the original Latin manuscript discovered in London in 1873, and aims to prove the existence of sentient demons called succubi and incubi - maleficent entities that feed on their prey through sexual intercourse. A fascinating book on esoteric demonology, "Demoniality" is highly recommended for those with an interest in the topic, and it is not to be missed by collectors of rare books pertaining to demons and theology. Ludovico Maria Sinistrari (1622 - 1701) was an Italian author and Franciscan priest. Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork.
