In another letter he says: 'The town is so fond of it, that the orange wenches and fruit women in the parks offer the books at the side of the coaches, and the prologue and epilogue are cried about the streets by the common hawkers.' It would be interesting to ascertain what there was in the state of public affairs in the spring of 1713, which created this enthusiasm. Swift, writing to Stella, alludes to a rehearsal of the play, but makes no criticism upon it; and Berkeley, who was in London at the time, and had a seat in Addison's box on the first night, is also silent about it. In a letter written, as it happens, by Bolingbroke, on the day that _Cato_ was produced, he indicates the signs of the time, as they appeared to a Tory statesman: 'The prospect before us,' he writes, 'is dark and melancholy. What will happen no man is able to foretell.' It was this sense of doubt and insecurity in the nation that gave significance to trifles. The political atmosphere was charged with electricity. The Tories, though in office, were far from feeling themselves secure, and both Harley and Bolingbroke were in correspondence with the Pretender. Atterbury, who was heart and soul with him, had just been made a bishop, Protestant ascendancy was in danger, the security of the country seemed to hang on the frail life of the Queen, and the strong party spirit of the time was easily fanned into a flame. We cannot now place ourselves in the position of the spectators whose passions gave such popularity to _Cato_. Its mild platitudes and rhetorical periods, its coldness and sobriety, seem ill fitted to arouse the fervour of playgoers, but Addison, whose good luck rarely failed him, was especially fortunate in the moment chosen for the representation of the play. Had _Cato_ exhibited genius of the highest order, it could not have been more successful. Cibber writes that it was acted in London five times a week for a month to constantly crowded houses, and when the tragedy was acted at Oxford, 'Our house,' he says, 'was in a manner invested, and entrance demanded by twelve o'clock at noon, and before one it was not wide enough for many who came too late for places.'[36] _Cato_ had the good fortune to run in London for thirty-five nights, and gained also some reputation on the continent. It is formed on the French model, and Addison was therefore praised by Voltaire as 'the first English writer who composed a regular tragedy.' He added that _Cato_ was 'a masterpiece.' If so, it is one of the masterpieces that has long ceased to be read. Little could its author have surmised that his tragedy, received with universal praise, had but a brief life to live, while the Essays which he had already contributed to the _Tatler_ and _Spectator_ would make his name familiar to future generations.
