Having heard some loose reports of conspiracies formed against him, he was so much alarmed, that he thought of immediately abdicating the government. And when, as I have before related, a man armed with a dagger was discovered near him while he was sacrificing, he instantly ordered the heralds to convoke the senate, and with tears and dismal exclamations, lamented that such was his condition, that he was safe no where; and for a long time afterwards he abstained from appearing in public. He smothered his ardent love for Messalina, not so much on account of her infamous conduct, as from apprehension of danger; believing that she aspired to share with Silius, her partner in adultery, the imperial dignity. Upon this occasion he ran in a great fright, and a very shameful manner, to the camp, asking all the way he went, "if the empire were indeed safely his."
No suspicion was too trifling, no person on whom it rested too contemptible, to throw him into a panic, and inuce him to take precautions for his safety, and meditate reveng, A man engaged in a litigation before his tribunal, having saluted him, drew him aside, and told him he had dreamt that he saw him murdered; and shortly afterwards, when his adversary came to deliver his plea to the emperor, the plaintiff, pretending to have discovered the murderer, pointed to him as the man he had seen in his dream; whereupon, as if he had been taken in the act, he was hurried away to execution. We are informed, that Appius Silanus was got rid of in the same manner, by a contrivance betwixt Messalina and Narcissus, in which they had their several parts assigned them. Narcissus therefore burst into his lord's chamber before daylight, apparently in great fright, and told him that he had dreamt that Appius Silanus had murdered him. The empress, upon this, affecting great surprise, declared she had the like dream for several nights successively. Presently afterwards, word was brought, as it had been agreed on, that Appius was come, he having, indeed, received orders the preceding day to be there at that time; and, as if the truth of the dream was sufficiently confirmed by his appearance at that juncture, he was immediately ordered to be prosecuted and put to death. The day following, Claudius related the whole affair to the senate, and acknowledged his great obligation to his freedmen for watching over him even in his sleep.
