From this it might be inferred that it proved an absolute failure, but such was hardly the case. Certainly it was not a perfect book. Zola himself afterwards wrote that the observer occasionally vanished from its pages, allowing the poet to appear, a poet who had drunk too much milk and eaten too much sugar. "It was not," said he, "a virile work; it was the cry of a weeping, rebellious child." But with all its faults it bore the impress of sincerity; Daudet's "Sapho," though far superior as literature, leaves one cold when one turns to it after perusing Zola's feverish pages. If the public did not rush to buy the "Confession," the critics, at all events, paid it considerable attention, and several assailed it unmercifully. For instance, Barbey d'Aurévilly, writing in the "Nain Jaune," declared that its "hero" was a toad, and that the author had simply spun out, over three hundred and twenty pages, what Cambronne, who commanded the Old Guard at Waterloo, had expressed in a single word. But what particularly roused Zola's ire was that "le Catholique hystérique," as he subsequently nicknamed Barbey d'Aurévilly, maliciously referred to the "Confession" as "Hachette's little book," whereas that firm had nothing to do with it. Zola therefore addressed a letter of protest to the "Nain Jaune."[21] But he had already decided to sever his connection with his employers. Since the death of M. Louis Hachette in the summer of 1864, the young man's position in the firm had been growing difficult. His superiors looked askance at his literary efforts, as if they thought that he wrote stories and articles in the time for which they paid him. Moreover, as they themselves did not deal in revolutionary literature, they did not care to have one of their clerks associated with such work. "La Confession de Claude" seemed to them too outspoken; and a few days after its publication, that is, at the end of November, 1865, one of the partners said to Zola: "You earn two hundred francs a month here. It is ridiculous! You have plenty of talent, and would do better to take up literature altogether. You would find glory and profit in it."[22]
