Demoniality; or, Incubi and Succubi

"Demoniality; or, Incubi and Succubi" by Ludovico Maria Sinistrari is a theological treatise written in the 17th century. The work examines the existence of Incubi and Succubi as rational beings capable of receiving salvation or damnation, putting forth a novel perspective on these entities often associated with supernatural sexual encounters. Sinistrari argues that these beings are distinct from angels and demons, filled with original ideas that intertwine faith with philosophical reasoning. At the start of the treatise, the author discusses the origins and definitions of terms related to demonic sexual conduct, particularly focusing on "Demoniality." He contrasts it with bestiality and cites the works of theologians and philosophers while presenting his argument that Incubi and Succubi are rational creatures capable of both corporeal and spiritual existence. Sinistrari elaborates on various instances and experiences surrounding these beings, providing historical evidence from notable authorities and drawing attention to the implications of such relationships on morality and theology. The opening sets a tone of academic inquiry blended with the intrigue of folklore, framing a complex exploration of a controversial subject that resonates with both religious and philosophical discourse.
