I, Claudius - Robert Graves [107]
The next day Rome was full of sailors who picketed the principal streets: whenever they met a knight or senator or public official they asked him the pass-word. The pass-word was "Neptune", and if he did not already know it he was given it and made to repeat it three times unless he wanted a beating. Nobody wanted a beating, and popular feeling now ran so strongly in sympathy with Postumus and against Tiberius and Livia that if a single favourable word had come from Germanicus the whole City, including the Guards and the City battalions, would have come over to him at once. But without Germanicus' support any rising in favour of Postumus would have meant civil war; and nobody had much confidence in Postumus' chances if it came to a struggle with Germanicus.
In this crisis the same Crispus who had antagonised Tiberius two years before by sending Clement to his death on the island [but had been forgiven] came forward and offered to redeem his fault by this time making sure of Postumus. Tiberius gave him a free hand. He found out somehow where Postumus' headquarters were and, going to him with a large sum of money which he said was for the payment of his sailors, who had already lost two working-days by this picketing work, he undertook to bring over the German bodyguard to Postumus' side as soon as he gave the signal. He had, he said, already given them enormous bribes. Postumus believed him. They arranged a meeting for two hours after midnight at a certain street corner where Postumus' sailors were also to assemble in force. They would march to Tiberius' Palace. Crispus would order the bodyguard to admit Postumus. Tiberius, Castor and Livia would be arrested, and Crispus said Sejanus, while not active in the plot, had undertaken to bring the Guards over in support of the new regime as soon as the first blow had been successfully struck: on condition that he retained his command. The sailors were punctual at the rendezvous but Postumus did not arrive. At that hour no citizens were in the street; so when a combined force of Germans from the bodyguard and picked men of Sejanus' suddenly fell on the sailors—who were mostly drunk and not in any regular formation—the pass-word "Neptune" lost its power. Many of them were killed on the spot, many more as they broke and ran, and the rest never once slowed down, it is said, before they reached Ostia again. Crispus and two soldiers had waylaid Postumus in a narrow alley between his headquarters and the rendezvous, stunned him with a sandbag, gagged and bound him, put him into a covered sedan and carried him off to the Palace. The next day Tiberius made a statement to the Senate. A certain slave of Postumus Agrippa's called Clement, he said, had caused a deal of unnecessary alarm in the City by impersonating his dead former master. This bold fellow had run away from the provincial knight who had bought him when Postumus' estate was sold and had hidden in a wood on the coast of Tuscany until his beard grew long enough to hide his receding chin—the chief point of dissimilarity between himself and Postumus. Some rowdy sailors at Ostia had pretended to believe in him, but only as an excuse for marching to Rome and creating a disturbance there. They had assembled in the suburbs a little before dawn that morning under his leadership with the object of marching to the centre of the City and plundering shops and private houses. When challenged by a force of Watchmen they had dispersed and deserted their leader, who had since been put to death; so the House need have no further anxiety about the matter.
I heard later that Tiberius pretended not to recognise Postumus when he was brought before him at the Palace and asked him, mockingly: "How did you happen to become one of the Caesars?" To which Postumus answered: "In the same way and on the same day as you did. Have you forgotten?" Tiberius told a slave to strike Postumus on the mouth for his insolence, and he was then put on the rack and asked to reveal his fellow-conspirators. But he would only tell scandalous anecdotes of the private life of Tiberius, which were so disgusting and so circumstantial that Tiberius lost his temper and battered his face in with his great bony fists. The soldiers finished the bloody work by beheading him and hacking him into pieces in the cellar of the Palace.
