Seneca, as one of the most enlightened men of his age, should have aimed at a character which would have been above the possibility of suspicion: but we must remember that charges such as those which were brought against him were the easiest of all to make, and the most impossible to refute. When we consider who were Seneca's accusers, we are not forced to believe his guilt; his character was indeed deplorably weak, and the laxity of the age in such matters was fearfully demoralising; but there are sufficient circumstances in his favour to justify us in returning a verdict of "Not guilty." Unless we attach an unfair importance to the bitter calumny of his open enemies, we may consider that the general tenor of his life has sufficient weight to exculpate him from an unsupported accusation.
Of Julia, Suetonius expressly says that the crime of which she was accused was uncertain, and that she was condemned unheard. Seneca, on the other hand, was tried in the Senate and found guilty. He tells us that it was not Claudius who flung him down, but rather that, when he was falling headlong, the Emperor supported him with the moderation of his divine hand; "he entreated the Senate on my behalf; he not only _gave_ me life, but even _begged_ it for me. Let it be his to consider," adds Seneca, with the most dulcet flattery, "in what light he may wish my cause to be regarded; either his justice will find, or his mercy will make, it a good cause. He will alike be worthy of my gratitude, whether his ultimate conviction of my innocence be due to his knowledge or to his will."
This passage enables us to conjecture how matters stood. The avarice of Messalina was so insatiable that the non-confiscation of Seneca's immense wealth is a proof that, for some reason, her fear or hatred of him was not implacable. Although it is a remarkable fact that she is barely mentioned, and never once abused, in the writings of Seneca, yet there can be no doubt that the charge was brought by her instigation before the senators; that after a very slight discussion, or none at all, Claudius was, or pretended to be convinced of Seneca's culpability; that the senators, with their usual abject servility, at once voted him guilty of high treason, and condemned him to death, and the confiscation of his goods; and that Claudius, perhaps from his own respect for literature, perhaps at the intercession of Agrippina, or of some powerful freedman, remitted part of his sentence, just as King James I. remitted all the severest portions of the sentence passed on Francis Bacon.
