In February 55 A.D. the young prince Britannicus was poisoned at Nero's table. He was the son of Claudius and the brother of Octavia--a possible claimant therefore to the Imperial throne. Nero, not more than eighteen years old, told the company quite coolly that it was an epileptic seizure, and the feast went on, while the dead boy was carried out and buried there and then in the rain--in a grave prepared before he had entered the dining-hall.[36] Ten months later Seneca wrote his tractate on Clemency. Nero should ask himself "Am I the elected of the gods to be their vice-gerent on earth? The arbiter of life and death to the nations?" and so forth. He is gently reminded of the great light that fronts the throne; that his anger would be as disastrous as war; that "Kings gain from kindness a greater security, while their cruelty swells the number of their enemies." Seneca wanders a good deal, but his drift is clear--and the wretchedness of his position. That Burrus and he had no knowledge of Nero's design to do away with his mother, is the verdict of Nero's latest historian, but to Seneca fell the horrible task of writing the explanatory letter which Nero sent to the Senate when the murder was done. Perhaps to judge him fairly, one would need to have been a Prime Minister. It may have been a necessary thing to do, in order to maintain the world's government, but the letter imposed on nobody, and Thrasea Paetus at once rose from his seat and walked conspicuously out. From the year 59 Nero was more than ever his own master. {46} His guardians' repeated condonations had set him free, and the lad, who had "wished he had never learned writing" when he had to sign his first death-warrant, began from now to build up that evil fame for which the murders of his brother and his mother were only the foundation. For three years Seneca and Burrus kept their places--miserably enough. Then Burrus found a happy release in death, and with him died the last of Seneca's influence.[37] Seneca begged the Emperor's leave to retire from the Court, offering him the greater part of his wealth, and it was refused. It had long been upon his mind that he was too rich. In 58 a furious attack was made upon him by "one who had earned the hate of many," Publius Suillius; this man asked in the Senate "by what kind of wisdom or maxims of philosophy" Seneca had amassed in four years a fortune equal to two and a half millions sterling; and he went on to accuse him of intrigue with princesses, of hunting for legacies, and of "draining Italy and the provinces by boundless usury."[38] There was probably a good deal of inference in these charges, if one may judge by the carelessness of evidence which such men show in all ages. Still Seneca felt the taunt, and in a book "On the Happy Life," addressed to his brother Gallic, he dealt with the charge. He did not claim to be a sage (17, 3); his only hope was day by day to lessen his vices--he was
