[13] Claudius was charmed to hear his own praises sung, and would have stayed longer to see the show. But the Talthybius¹ of the gods laid a hand on him, and led him across the Campus Martius, first wrapping his head up close that no one might know him, until betwixt Tiber and the Subway he went down to the lower regions. His freedman Narcissus had gone down before him by a short cut, ready to welcome his master. Out he comes to meet him, smooth and shining (he had just left the bath), and says he:“What make the gods among mortals?” “Look alive,” says Mercury, “go and tell them we are coming.” Away he flew, quicker than tongue can tell it. It is easy going by that road, all down hill. So although Claudius had a touch of the gout, in a trice they were come to Dis's door. There lay Cerberus, or, as Horace puts it, the hundred-headed monster.

Odes ii, 13, 35

Claudius was a trifle perturbed (it was a little white bitch he used to keep for a pet) when he spied this black shag-haired hound, not at all the kind of thing you could wish to meet in the dark. In a loud voice he cried, “Claudius is coming!” All marched before him singing, “The lost is found, O let us rejoice together!”² Here were found C. Silius consul elect, Juncus the ex-praetor, Sextus Traulus, M. Helvius,[p. 403] Trogus, Cotta, Vettius Valens, Fabius, Roman Knights whom Narcissus had ordered for execution. In the midst of this chanting company was Mnester the mime, whom Claudius for honour's sake had made shorter by a head. The news was soon blown about that Claudius had come: to Messalina they throng: first his freedmen, Polybius, Myron, Harpocras, Amphaeus, Pheronactus, all sent before him by Claudius that he might not be unattended anywhere; next two prefects, Justus Catonius and Rufrius Pollius; then his friends, Saturninus Lusius and Pedo Pompeius and Lupus and Celer Asinius, these of consular rank; last came his brother's daughter, his sister's daughter, sons-in-law, fathers and mothers-in-law, the whole family in fact. In a body they came to meet Claudius; and when Claudius saw them, he exclaimed, “Friends everywhere, on my word! How came you all here?” To this Pedo Pompeius answered, "What, cruel man? How came we here? Who but you sent us, you, the murderer of all the friends that ever you had? To court with you! I'll show you where their lordships sit.'
