In 1866, after the Salon jury had rejected two of Manet's works, Émile Zola came to his defense with a series of articles filled with strongly expressed, uncompromising praise. In 1867 he published a book which contains the prediction, "Manet's place is destined to be in the Louvre." This book appears on Zola's desk in Manet's portrait of the writer (1868). In May of that year the Paris World's Fair opened its doors, and Manet, at his own expense, exhibited 50 of his works in a temporary structure, not far from Gustave Courbet's private exhibition. This was in keeping with Manet's view, expressed years later to his friend Antonin Proust, that his paintings must be seen together in order to be fully understood. Although Manet insisted that a painter be "resolutely of his own time" and that he paint what he sees, he nevertheless produced two important religious works, the Dead Christ with Angels and Christ Mocked by the Soldiers, which were shown at the Salons of 1864 and 1865, respectively, and ridiculed. Only Zola could defend the former work on the grounds of its vigorous realism while playing down its alleged lack of piety. It is also true that although Manet despised the academic category of "history painting" he did paint the contemporary Naval Battle between the Kearsarge and the Alabama (1864) and the Execution of Maximilian (1867). The latter is based upon a careful gathering of the facts surrounding the incident and composed, largely, after Francisco Goya's Executions of the Third of May, resulting in a curious amalgam of the particular and the universal. Manet's use of older works of art in elaborating his own major compositions has long been, and continues to be, a problematic subject, since the old view that this procedure was needed to compensate for the artist's own inadequate imagination is rapidly being discarded. Late Works

Although Manet influenced the impressionists during the 1860s, during the next decade it appears that it was he who learned from them. His palette became lighter; his stroke, without ever achieving the analytical intensity of Claude Monet's, was shorter and more rapid. Nevertheless, Manet never cultivated pleinairism seriously, and he remained essentially a figure and studio painter. Also, despite his sympathy for most of the impressionists with whom the public associated him, he never exhibited with them at their series of private exhibitions which began in 1874. Manet had his first resounding success since the Spanish Singer at the Salon of 1873 with his Bon Bock, which radiates a touch and joviality of expression reminiscent of Frans Hals, in contrast to Manet's usually austere figures.
