I, Claudius - Robert Graves [160]
The first thing that happened was that Helen became an invalid—we know now that there was nothing wrong with her, but Livilla had given her the choice of taking to her bed as if she were ill or of taking to her bed because she was ill. She was moved from Rome to Naples, where the climate was supposed to be healthier. Tiberius gave leave for the marriage to be postponed indefinitely, but addressed Sejanus as his son-in-law as if it had already taken place. He elevated him to senatorial rank and made him his colleague in the Consulship and a pontiff. But he then did something else which quite cancelled these favours: he invited Caligula to Capri for a few days and then sent him back armed with a most important letter to the Senate. In the letter he said that he had examined the young man, who was now his heir, and found him of a very different temper and character from his brothers and would, indeed, refuse to believe any accusations that might be brought against his morals or loyalty. He now entrusted Caligula to the care of Alius Sejanus, his fellow-Consul, begging him to guard the young man from all harm. He appointed him a pontiff too, and a priest to Augustus.
When the City heard about this letter there was great rejoicing. By making Sejanus responsible for Caligula's safety Tiberius was understood to be warning him that his feud with Germanicus' family had now been carried far enough. Sejanus' Consulship was regarded as a bad omen for him: this was Tiberius' fifth time in office and every one of his previous colleagues had died in unlucky circumstances: Varus, Gnaeus Piso, Germanicus, Castor. So new hope arose that the nation's troubles would soon be over: a son of Germanicus would rule over them. Tiberius might perhaps kill Nero and Drusus but he had clearly decided to save Caligula: Sejanus would not be the next Emperor.
Everyone whom Tiberius now sounded on the subject seemed so genuinely relieved at his choice of a successor—for somehow they had persuaded themselves that Caligula had inherited all his father's virtues—that Tiberius, who recognised real evil whenever he saw it and had told Caligula frankly that he knew he was a poisonous snake and had spared him for that very reason, was much amused, and thoroughly pleased. He could use Caligula's rising popularity as a check to Sejanus and Livilla.
He now took Caligula somewhat into his confident and gave him a mission: to find out by intimate talks with Guardsmen, which of their captains had the greatest personal influence in the Guards' camp, next to Sejanus; and then to make sure that he was equally bloody-minded and fearless. Caligula dressed up in a woman's wig and clothes and, picking up a couple of young prostitutes, began frequenting the suburban taverns where the soldiers drank in the evening. With a heavily made up face and. padded figure he passed for a woman, a tall and not very attractive one, but still, a woman. The account that he gave of himself in the taverns was that he was being kept by a rich shop keeper who gave him plenty of money—on the strength of which he used to stand drinks all round. This generosity made him very popular. He soon came to know a great deal of camp gossip, and the name that was constantly coming up in conversations was that of a captain called Macro. Macro was the son of one of Tiberius' freedmen, and from all accounts was the toughest fellow in Rome. The soldiers all spoke admiringly of his drinking feats and his wenching and his domination of the other captains and his presence of mind in difficult situations.
Even Sejanus was afraid of him, they said: Macro was the only man who ever stood up to him. So Caligula picked up with Macro one evening and secretly introduced himself: the two went off for a stroll together and had a long talk.
Tiberius then began writing a queer series of letters to the Senate, now saying that he was in a bad state of health and almost dying, and now that he had suddenly recovered and would arrive in Rome any moment. He wrote very queerly too about Sejanus, mixing extravagant praises with petulant rebukes; and the general impression conveyed was that he had become senile and was losing his senses. Sejanus was so puzzled by these letters that he could not make up his mind whether to attempt a revolution at once or to hold on to his position, which was still very strong, until Tiberius died or could be removed from power on the grounds of imbecility. He wanted to visit Capri and find out for himself just how things stood with Tiberius. He wrote asking permission to visit him on his birthday, but Tiberius answered that as Consul he should stay at Rome; it was irregular enough for himself to be permanently absent, Sejanus then wrote that Helen was seriously ill at Naples and had begged him to visit her: could he not be permitted to do so, just for a day? and from Naples it was only an hour's row to Capri. Tiberius answered that Helen had the best doctors and must be patient: and that he himself was really coming to Rome now and wanted Sejanus to be there to welcome him. At about the same time he quashed an indictment against an ex-Governor of Spain, whom Sejanus was accusing of extortion, on the grounds that the evidence was conflicting. He had never before failed to support Sejanus in a case of the sort. Sejanus began to be alarmed.
