This vintage book deals with the subject of Satanism and demonology, looking in particular at the Black Mass and incubi and succubi. A Black Mass refers to a ritual wherein the Traditional Latin Mass of the Catholic Church is inverted, popularised in the nineteenth century by French literature in such books as Jules Michelet’s “Satanism and Witchcraft” and Joris-Karl Huysmans’s “Là-bas”; while succubi and incubi are demons that prey upon sleeping victims by engaging in sexual activity with them while they are sleeping. “The Black Mass – Of the Loves of the Incubi and Succubi” will appeal to those with an interest in the occult and is not to be missed by fans and collectors of Summers’ seminal work. Augustus Montague Summers (1880 – 1948) was an English clergyman and author most famous for his studies on vampires, witches and werewolves—all of which he believed to be very much real. He also wrote the first English translation of the infamous 15th-century witch hunter’s manual, the “Malleus Maleficarum”, in 1928. Other notable works by this author include: “A Popular History of Witchcraft” (1937), “Witchcraft and Black Magic” (1946), and “The Physical Phenomena of Mysticism” (1947). 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 a specially-commissioned new biography of the author.
