His life was now passed between Paris and Cirey--society and solitude. He and the du Châtelets shared the same house in the capital; their studies and their amusements were in common. We are told[4] that on one occasion, when madame du Châtelet went to court, and engaged in play, during which she lost a great deal of money, Voltaire told her in English that she was being cheated. The words were understood by others who were present, and the poet thought it prudent to absent himself for a time. He asked refuge from the duchess du Maine at Sceaux. Here he passed two months in the strictest retreat; and when danger was past, he repaid his hostess by remaining in her chateau, and contributing to her recreation by getting up plays, and writing for her. "Zadig" and others of his tales were composed on this occasion. Operas, plays, concerts, and balls varied the amusements. Madame du Châtelet and Voltaire took parts in these theatricals. The lady was an admirable actress, as well as musician: she shone in comedy, where her gaiety, grace, and vivacity had full play. Voltaire was also a good actor. The part of Cicero in his own tragedy of "Rome Sauvée" was his favourite part. At other times, leaving these pleasures, he and his friend retired to Cirey and to labour. We have an amusing account of several of their migrations, from the pen of Longchamp, who, from being the valet of madame du Châtelet, became elevated into the secretary of Voltaire. There is a great contrast between this man's account, and the letters before quoted of madame de Graffigny. In both descriptions, we find mentioned the vivacity and petulance both of the poet and his friend; but the darker shadows thrown by irritability and quarrelling, do not appear in the pages of Longchamp; and, above all, the fair disciple of Newton is delineated in far more agreeable colours. "Madame du Châtelet," he writes, "passed the greater part of the morning amidst her books and her writings, and she would never be interrupted. But when she left her study, she was no longer the same woman--her serious countenance changed into one expressive of gaiety, and she entered with ardour into all the pleasures of society. Although she was then forty, she was the first to set amusement on foot, and to enliven it by her wit and vivacity." Nor does he make any mention of the violence and ill-humour from which her guest suffered so piteously. "When not studying," he remarks, "she was always active, lively, and good-humoured." At Cirey, she was equally eager to afford amusement to her friends. "When the report of her arrival," writes Longchamp, "was spread through the neighbouring villages, the gentry of the country around came to pay their respects. They were all well received; those who came from a distance were kept for several weeks at the chateau. To amuse both herself and her guests, madame du Châtelet set on foot a theatre. She composed farces and
