as queen of the Succubi. The connexion here is very plain, for Martin Delrio, 5, 7, in his Disquisitionum Magicarum Libri Sex, I, 178, (Louvain, 1599), definitely states: “Axioma I sit, solent Malefici et Lamiae cum daemonibus, illi quidem succubis, hae uero incubis, actum Venerium exercere…. Axioma II potest etiam ex huiusmodi concubitu daemonis incubi proles nasci.” Michael Psellus (Μιχαὴλ ὁ Ψελλός), the famous Byzantine scholar of the tenth century, in his treatise, De Operatione daemonum dialogus (graece et latine cum notis Gaulmini, Paris, 1615), says that a monk of Mesopotamia, named Marcus, informed him that demons here capable of sensual passions, “Quemadmodum et sperma nonnulli eorum emittunt et uermes quosdam spermate procreant. At incredibile est, inquam, excrementi quicquam daemonibus inesse, uasaue spermatica et uitalia. Uasa quidem eis, inquit ille, huiusmodi nulla insunt, superflui autem seu excrementi nescio quid emittunt hoc mihi asserenti credito.” The learned authors of the Malleus Maleficarum discuss, “Whether Children can be Generated by Incubi and Succubi” (Part I, Question iii), and “By which Devils are the Functions of Incubus and Succubus Practised” (Part I, Question iv). Appeal is made to the authority of S. Augustine, who, De Trinitate, III, says “That devils do indeed collect human semen, by means of which they are able to produce bodily effects: but this cannot be done without some local movement, therefore demons can transfer the semen which they have collected and inject it into the bodies of others.” Moreover, Sprenger and Kramer inquire: “Is it Catholic to affirm that the functions of Incubi and Succubi belong indifferently and equally to all unclean spirits?” They reply: “It seems that it is so; for to affirm the opposite would be to maintain that there is some good order among them.” Now the vampire is certainly an unclean spirit, whether it be that the body is animated by some demon, or whether it be the man himself who is permitted to enter his corpse and energize it and accordingly it is Catholic to believe that a vampire can copulate with human beings. Nor are there lacking instances of this. We have the well-known history related by Phlegon of Tralles where Machates enjoys Philinnion, who has returned (albeit he knows it not) from her tomb; and in modern Greece it is quite commonly held that the vrykolakas will revisit
