Chapter XVI.

Of the subjection of the devils, which they show to their own princes, as seen in a brother’s victim.

But that unclean spirits are ruled over by worse powers and are subject to them we not only find from those passages of Scripture, recorded in the gospels when the Pharisees maligned the Lord, and He answered “If I by Beelzebub the prince of the devils cast out devils,” 1543 but we are also taught this by clear visions and many experiences of the saints, for when one of our brethren was making a journey in this desert, as day was now declining he found a cave and stopped there meaning to say his evening office in it, and there midnight passed while he was still singing the Psalms. And when after he had finished his office he sat down a little before refreshing his wearied body, on a sudden he began to see innumerable troops of demons gathering together on all sides, who came forward in an immense crowd, and a long line, some preceding and others following their prince; who at length arrived, being taller and more dreadful to look at than all the others; and, a throne having been placed, he sat down as on some lofty tribunal, and began to investigate by a searching examination the actions of each one of them; and those who said that they had not yet been able to circumvent their rivals, he commanded to be driven out of his sight with shame and ignominy as idle and slothful, rebuking them with angry wrath for the waste of so much time, and for their labour thrown away: but those who reported that they had deceived those assigned to them, he dismissed before all with the highest praise amidst the exultation and applause of all, as most brave warriors, and most renowned as an example to all the rest: and when in this number some most evil spirit had presented himself, in delight at having to relate some magnificent triumph, he mentioned the name of a very well known monk, and declared that after having incessantly attacked him for fifteen years, he had at last got the better of him, so as to destroy him that very same night by the sin of fornication, for that he had not only impelled him to commit adultery with some consecrated maid, but had actually persuaded him to keep her and marry her. And when there arose shouts of joy at this narrative, he was extolled with the highest praise by the prince of darkness, and departed crowned with great honours. And so when at break of day the whole swarm of demons had vanished from his eyes, the brother being doubtful about the assertion of the unclean spirit, and rather thinking that he had desired to entice him by an ancient customary deceit, and to brand an innocent brother with the crime of incest, being mindful of those words of the gospel; viz., that “he abode not in the truth because there is no truth in him. When he speaketh a lie, he speaketh of his own, for he is a liar, and its father,” 1544 he made his way to Pelusium, where he knew that the man lived, whom the evil spirit declared to be destroyed: for the brother was very well known to him, and when he had asked him, he found that on the same night on which that foul demon had announced his downfall to his company and prince, he had left his former monastery, and sought the town, and had gone astray by a wretched fall with the girl mentioned.
