Thus the Revizor occupied the mind of the author over a period of eight years, and resulted in a product which from the point of view of characterization and dramatic technique is almost flawless. Yet far more important is the fact that the play marked an epoch in Gogol's own literary development. When he began on it, his ambitions did not rise above making it a comedy of pure fun, but, gradually, in the course of his working on it, the possibilities of the subject unfolded themselves and influenced his entire subsequent career. His art broadened and deepened and grew more serious. If Pushkin's remark, that "behind his laughter you feel the sad tears," is true of some of Gogol's former productions, it is still truer of the Revizor and his later works. A new life had begun for him, he tells us himself, when he was no longer "moved by childish notions, but by lofty ideas full of truth." "It was Pushkin," he writes, "who made me look at the thing seriously. I saw that in my writings I laughed vainly, for nothing, myself not knowing why. If I was to laugh, then I had better laugh over things that are really to be laughed at. In the Inspector-General I resolved to gather together all the bad in Russia I then knew into one heap, all the injustice that was practised in those places and in those human relations in which more than in anything justice is demanded of men, and to have one big laugh over it all. But that, as is well known, produced an outburst of excitement. Through my laughter, which never before came to me with such force, the reader sensed profound sorrow. I myself felt that my laughter was no longer the same as it had been, that in my writings I could no longer be the same as in the past, and that the need to divert myself with innocent, careless scenes had ended along with my young years." With the strict censorship that existed in the reign of Czar Nicholas I, it required powerful influence to obtain permission for the production of the comedy. This Gogol received through the instrumentality of his friend, Zhukovsky, who succeeded in gaining the Czar's personal intercession. Nicholas himself was present at the first production in April, 1836, and laughed and applauded, and is said to have remarked, "Everybody gets it, and I most of all." Naturally official Russia did not relish this innovation in dramatic art, and indignation ran high among them and their supporters. Bulgarin led the attack. Everything that is usually said against a new departure in literature or art was said against the Revizor. It was not original. It was improbable, impossible, coarse, vulgar; lacked plot. It turned on a stale anecdote that everybody knew. It was a rank farce. The characters were mere caricatures. "What sort of a town was it that did not hold a single honest soul?"
