The Gospel of Mark says: “And Jesus asked him: What is your name? And he answered, “My name is Legion, for we are many” (Mark 5:9). Satan, Beelzebub, Lucifer... - the devil has many faces, and the fight against him has been waged throughout the entire existence of the human race. Another attempt to trace the evolution of the image of the devil in the religious, mythological, philosophical, cultural and historical space was made in 1911 by the famous Russian prose writer, playwright, publicist, feuilletonist, literary and theater critic Alexander Amfitheatrov (1862–1938) in his treatise “The Devil in Everyday Life, legend and in the literature of the Middle Ages." The experience was not unsuccessful. The great Bulgakov used his book as a reference book when working on The Master and Margarita, creating images of Woland and his retinue. The birth, death and offspring of the devil, demonic obsessions, temptations, intrigues, hellish torments, incubi and succubi, witches, possessed people, passion for magic and its consequences, the struggle of the Church with the devil, etc. - all this can be found on the pages of the “encyclopedia” we publish. in the field of demonology.
