In the centre of Hell I saw a dark and horrible-looking abyss, and into this Lucifer was cast, after being first strongly secured with chains; thick clouds of sulphureous black smoke arose from its fearful depths, and enveloped his frightful form in the dismal folds, thus effectually concealing him from every beholder. God himself had decreed this; and I was likewise told, if I remember right, that he will be unchained for a time fifty or sixty years before the year of Christ 2000. The dates of many other events were pointed out to me which I do not now remember; but a certain number of demons are to be let loose much earlier than Lucifer, in order to tempt men, and to serve as instruments of the divine vengeance. I should think that some must be loosened even in the present day, and others will be set free in a short time.
