publishing the Elements of Newton in 1738, and contending for a prize proposed by the Academy of Sciences. At the same time he produced in rapid succession Alzire, Mahomet, and Merope. His fame was now become European. Frederic of Prussia, Stanislaus, and other sovereigns honoured him, or were honoured by his correspondence. But the perpetual intrigues of his enemies at home deprived him of repose, and even at Cirey he was not always free from troubles and altercations. Upon the death of Madame du Châtelet, in 1749, he accepted the often urged invitation of Frederic, and took up his residence at the Court of Berlin. But the friendship of the king and the philosopher was not of long duration. A violent quarrel with the geometrician, Maupertuis, who was also living under the protection of Frederic, ended, after some ineffectual attempts at accommodation, in Voltaire’s departure from Frederic’s society and dominions (1753). He had just published his Siècle de Louis XIV., which was shortly followed by the Essai sur les Mœurs. After a few more wanderings, for the versatility of his talent seemed to require a corresponding variety of abode, Voltaire finally fixed himself at Ferney, near Geneva, in the sixty-fifth year of his eventful life, and began to enjoy at leisure his vast reputation. From all parts of Europe strangers undertook pilgrimages to this philosophic shrine. Sovereigns took pride in corresponding with the Patriarch, as he was called by the numerous sect of free-thinkers, and self-styled _philosophers_, who looked up to him as their teacher and leader. The Society of Philosophers at Paris, now employed in their great work, the Encyclopædia, which, from the moment of its ill-judged prohibition by the government had assumed the character of an antichristian manifesto, looked up to Voltaire as the acknowledged chief of their party. He furnished some of the most important articles in the work. His whole mind seemed now to be bent on one object, the subversion of the Christian religion. Innumerable miscellaneous compositions, different in form, and generally anonymous, indeed often disavowed, were marked by this pernicious tendency. “I am tired,” he is reported to have said, “of hearing it repeated that twelve men were sufficient to found Christianity: I will show the world that _one_ is sufficient to destroy it!” Half a century has elapsed, and the event has not justified the truth of this boast: he mistook his own strength, as many other unbelievers have done. These impious extravagances were not, however, the only occupation of the twenty years which intervened between Voltaire’s establishment at Ferney and his death. In the defence of Sirven, Lally, Labarre, Calas, and others, who at several times were objects of unjust condemnation by the judicial tribunals, he exerted himself with a zeal as indefatigable as it was meritorious. Ferney, under his protection, grew to a considerable village, and the
