Midway in this period Cicero divorced his wife after thirty years of wedlock, seemingly from some dissatisfaction over her financial management, and soon after married a wealthy young ward. This is the least pleasing chapter of his private life, but perhaps the mortification and suffering it entailed were a sufficient penalty. His only daughter Tullia's death in 45 B.C. nearly broke the father's heart. Whatever the reason, Cicero was certainly not in the secret of Caesar's assassination. Twice in letters to members of the conspiracy in later months he begins: "How I wish you had invited me to your glorious banquet on the Ides of March." "There would have been no remnants," he once adds. That is, Antony would not have been left alive. We have now reached the last two years--perhaps the most creditable time--in Cicero's eventful life. This period runs from March 15th, 44 B.C., to December 7th, 43 B.C. It was one long struggle, first covert, then open, between Antony and the slayers of Caesar. Cicero's energy and eloquence soon made him the foremost voice in the Senate once more. For the first time since his exile, he is now speaking out courageously his own real sentiments. His public action is in harmony with his own convictions. The cause was not hopeless by any means, so far as the destruction of Antony would have been a final triumph. Indeed, that wild career seemed near its end, when Octavian's duplicity again threw the game into his rival's reckless hands. However, few students of history imagine that any effective restoration of senatorial government was possible. The peculiar pathos of Cicero's end, patriot as he was, is this: it removed one of the last great obstacles to the only stable and peaceful rule Rome could receive--the imperial throne of Augustus. This last period is however among the most creditable, perhaps the most heroic, in Cicero's career. Its chief memorials are the fourteen extant orations against Antony. The comparative sincerity of these 'Philippics,' and the lack of private letters for much of this time, make them important historical documents. The only one which ranks among his greatest productions--perhaps the classic masterpiece of invective--is the 'Second Philippic.' This was never delivered at all, but published as a pamphlet. This unquestioned fact throws a curious light on passages like--"He is agitated, he perspires, he turns pale!" describing Antony at the (imaginary) delivery of the oration. The details of the behavior of Catiline and others may be hardly more authentic. The 'Ninth Philippic' is a heartfelt funeral eulogy on that same Sulpicius whom he had ridiculed in the 'Pro Murena.' "The milestones into headstones turn, And under each a friend."
