Such was the object of demonology, as taught by its most orthodox professors. Yet other systems of it were devised, which had their origin in causes attending the propagation of Christianity. For it must have been a work of much time to eradicate the universal belief, that the Pagan deities, who had become so numerous as to fill every part of the universe, were fabulous beings. Even many learned men were induced to side with the popular opinion on the subject, and did nothing more than endeavour to reconcile it with their acknowledged systems of demonology. They taught that such heathen objects of reverence were fallen angels in league with the prince of darkness, who, until the appearance of our Saviour, had been allowed to range on the earth uncontrolled, and to involve the world in spiritual darkness and delusion. According to the various ranks which these spirits held in the vast kingdom of Lucifer, they were suffered, in their degraded state, to take up their abode in the air, in mountains, in springs, or in seas. But, although the various attributes ascribed to the Greek and Roman deities, were, by the early teachers of Christianity, considered in the humble light of demoniacal delusions, yet for many centuries they possessed great influence over the minds of the vulgar. In the reign of Adrian, Evreux, in Normandy, was not converted to the Christian faith, until the devil, who had caused the obstinacy of the inhabitants, was finally expelled from the temple of Diana. To this goddess, during the persecution of Dioclesian, oblations were rendered by the inhabitants of London. In the 5th century, the worship of her existed at Turin, and incurred the rebuke of St. Maximus. From the ninth to the fifteenth century, several denunciations took place of the women who, in France and Germany, travelled over immense spaces of the earth, acknowledging Diana as their mistress and conductor. In rebuilding St. Paul’s cathedral, in London, remains of several of the animals used in her sacrifices were found; for slight traces of this description of reverence, subsisted so late as the reign of Edward the First, and of Mary. Apollo, also, in an early period of Christianity, had some influence at Thorney, now Westminster. About the 11th century, Venus formed the subject of a monstrous apparition, which could only have been credited from the influence which she was still supposed to possess. A young man had thoughtlessly put his ring around the marble finger of her image. This was construed by the Cyprian goddess as a plighted token of marriage; she accordingly paid a visit to her bridegroom’s bed at night, nor could he get rid of his bed-fellow until the spells of an exorcist had been invoked for his relief. In the year 1536, just before the volcanic eruption of Mount Etna, a Spanish merchant, while travelling in Sicily, saw the apparition of Vulcan attended by twenty of his Cyclops, as they were escaping from the
