This ardour for composition, and these pleasures, were suddenly arrested by the afflicting event of madame du Châtelet's death. She died soon after her confinement, unexpectedly, when all danger seemed past. Whatever might have been the disputes of the friends, these did not shake their friendship; and if they clouded, at intervals, the happiness they derived, they left no evil trace behind. Voltaire was plunged in the deepest affliction; the expressions he uses mark the truth of his regrets. "I do not fear my grief," he writes to his friend, the marquis d'Argental; "I do not fly from objects that speak to me of her. I love Cirey; and although I cannot bear Luneville, where I lost her in so frightful a manner, yet the places which she adorned are dear to me. I have not lost a mistress; I have lost the half of myself,--a soul for which mine was made,--a friend of twenty years. I feel as the most affectionate father would towards an only daughter. I love to find her image everywhere; to converse with her husband and her son."--"I have tried to return to 'Catiline;' but I have lost the ardour I felt when I could show her an act every two days. Ideas fly from me; I find myself, for hours together, unable to write; without a thought for my work: one idea occupies me day and night." To these laments he adds her eulogy, in another letter, with which we may conclude the subject. Her errors were the effect of the times in which she lived, and of an ardent temper. We would deprecate any return to a state of society that led the wisest into such grievous faults, but we will not defraud the victim of the system of the praise which, on other scores, she individually merited.[5] "A woman," writes Voltaire, "who translated and explained Newton, and translated Virgil, without betraying in her conversation that she had achieved these prodigies; a woman who never spoke ill of any one, and never uttered a falsehood; a friend, attentive and courageous in her friendship: in a word, a great woman, whom the common run of women only knew by her diamonds and dress. Such must I weep till the end of my life."
