'Palpable intercourses between the bad genii and mankind' are more frequent than Dr. Glanvil was disposed to believe; and he must have been conversant with the acts of Incubus and Succubus. In the first age (orbe novo c[oe]loque recenti) under the Saturnian regime, 'while yet there was no fear of Jove,'[83] innocence prevailed undisturbed; but soon as the silver age was inaugurated by the usurpation of Jove, _liaisons_ between gods and mortals became frequent. Love affairs between good or bad 'genii' and mankind are of common occurrence in the mythology of most peoples. In the romance-tales of the middle age lovers find themselves unexpectedly connected with some mysterious being of inhuman kind. The writers in defence of witchcraft quote Genesis vi. in proof of the reality of such intercourses; and Justin Martyr and Tertullian, the great apologists of Christianity, and others of the Fathers, interpret _Filios Dei_ to be angels or evil spirits who, enamoured with the beauty of the women, begot the primeval giants.[84] [83] 'Jove nondum Barbato.' [84] Milton indignantly exclaims, alluding to this common fancy of the leaders of the Primitive Church, 'Who would think him fit to write an apology for Christian faith to the Roman Senate that could tell them "how of the angels"--of which he must needs mean those in Genesis called the Sons of God--"mixing with women were begotten the devils," as good Justin Martyr in his Apology told them.' (_Reformation in England_, book i.). And 'Clemens Alexandrinus, Sulpicius Severus, Eusebius, &c., make a twofold fall of angels--one from the beginning of the world; another a little before the deluge, as Moses teacheth us, openly professing that these _genii_ can beget and have carnal copulation with woman' (_Anatomy of Melancholy_, part i.). Robert Burton gives in his adhesion to the sentiments of Lactantius (xiv. 15). It seems that the later Jewish devils owe their origin (according to the Talmudists, as represented by Pererius in the _Anatomy_) to a former wife of Adam, called Lilis, the predecessor of Eve.
