Émilie and Voltaire in crisis
In 1734, Émilie du Châtelet and Voltaire attended the wedding of the Duc de Richelieu in Burgundy at the Château de Montjeu, illustrated here. It was the first time they had travelled together publicly and it proved disastrous, because the gendarmes knew just where to find Voltaire when a warrant was issued for his arrest over a banned book, Philosophical Letters. The lovers' own letters at the time continue the story.
From Émilie to Pierre-Louis de Maupertuis, her mathematics tutor, April 1734
I’d like you to give me some lessons here [Montjeu], but since you’re remaining in Paris I’ll hurry my return and get there at the end of June at the latest. I flatter myself that I’ll then prove somewhat less unworthy of your tutoring.
I’m not aiming to succeed in geometry for my own sake; I’m more motivated by my pride in your reputation. It doesn’t seem right for anyone who has you as a teacher to make such mediocre progress, and I can’t tell you how much it shames me.
I’m here in the most beautiful place in the world, with the most wonderful people: all that’s missing is the pleasure of seeing and listening to you. When I told Voltaire I was writing to you, he asked me to tell you a thousand things on his account—he’s worried, quite rightly, about the fate of his Letters. He’s immensely flattered that his enemies believe you contributed to his essays on Newton, and if it weren’t for the fear that he’ll be arrested for writing them, I think your approbation would make up for everything else.
From Voltaire to La Condamine of the Academy of Sciences in Paris, January 1734
You will soon be seeing Madame du Châtelet. The friendship with which she honours me has not failed me in this pass. Her mind is worthy of you and her heart is worthy of her mind. The good offices she extends to her friends are as great as the keenness with which she learns languages and geometry, and when she has rendered us every imaginable service, she still thinks she has performed none; such is her intellect and her learning that she believes she knows nothing and has no idea how intelligent she is. Take her to your heart and let us be her admirers and friends as long as we live.
From Émilie to Aldonce de Sade, May 1734
We must conclude that my friend Voltaire—you know my feelings for him—is in prison at Auxonne, near Dijon. He left us several days ago to take the waters at Plombières (his health has long required it) but gendarmes sent here by the Governor of Burgundy have brought a warrant for his arrest and he is to be imprisoned at Auxonne until further notice. … I can’t tell you how devastating this is; I can hardly bear to think of my best friend, whose health is so terrible, locked in a prison where he will surely die of suffering, if not of some illness. I have no news of him and can’t defy the might of such a minister [Chauvelin, Minister of Police] by sending him mine … But of what use to Voltaire are our tears and regrets? I have no hope. Monsieur de Chauvelin is inflexible and I am inconsolable: I’ll never get over the loss of such a friend. Flirtation or resentment—anything at all—will do to console us after losing a lover; but time, which heals all wounds, would only poison mine …
I’m going at once to my château in the country. I can’t stand society any longer. Men are so false, so unjust, so prejudiced, so tyrannical! I must either live alone, or with people who think as you do. One spends one’s existence with envious vipers—what’s the use being alive and young? I’d prefer to be fifty years old and live in the country with my friend, Madame de Richelieu and you. Alas, we spend our lives planning to be happy and we never manage it. Farewell, monsieur: I can feel my suffering diminish even as I write to you, but I don’t want to strain your friendship.
What Voltaire had actually done after the scare at Montjeu was take refuge incognito at Cirey, a former hunting lodge in the Champagne that belonged to the Du Châtelet family. In 1735 Émilie eventually joined him there.
