The relationship between an ambitious, politically powerful woman and the most celebrated writer of the age became one of mutual benefit. Both were mindful that they were playing before an immense, influential audience. Catherine recognized that a letter to Voltaire, which could be passed along to his friends, was potentially a message to the intelligentsia of Europe. For Voltaire, what could be more flattering than to have another ruling sovereign become his royal disciple? He addressed her as “the Semiramis of the North,” “Saint Catherine,” and “Our Lady of St. Petersburg.” In return, she showered him with sable pelisses and jeweled snuffboxes, and sent diamonds to Madame Denis. But it was a relationship that thrived on distance; despite the intimacy of their correspondence, the empress and the patriarch never met. Near the end of his life, when Voltaire was toying with the idea of paying Saint Catherine his personal respects, this appeared to be the last thing she wanted. Perhaps nervous about exposing her country or herself to Voltaire’s analytical eye, she wrote urgently to Grimm, “For God’s sake, try to persuade the octogenarian to stay at home. What should he do here? He would either die here or on the road from cold, weariness and bad roads. Tell him that
Even before she first wrote to Voltaire in 1763, Catherine had reached out to another towering Enlightenment figure, Denis Diderot. Diderot, born in a small town near Dijon in 1713, was as warmhearted as Voltaire was cynical, as rough-hewn as Voltaire was sophisticated and polished, and retained though life the innocence of a child and the enthusiasms of adolescence. According to Catherine, Diderot was “in certain ways … a hundred, in others not yet ten.” Intending as a boy to become a priest, he attended a Jesuit school for seven years (his brother became a priest) and the University of Paris, and became a translator of English books into French. Increasingly, he was fascinated by the whole universe of knowledge: mathematics, biology, chemistry, physics, anatomy, Latin, Greek, history, literature, art, politics, and philosophy. As a young man, he had rejected the biblical God as a monster of cruelty and the Catholic Church as a fountainhead of ignorance. He saw nature, which, he noted, made no distinction between good and evil, as the only permanent reality. He was arrested and imprisoned. Released, he became the founder and chief editor of the new
From the first, Voltaire praised and encouraged. To d’Alembert he wrote, “You and M. Diderot are accomplishing a work which will be the glory of France and the shame of those who persecute you. Of eloquent philosophers, I recognize only you and him.” Six years later, when the project was again in trouble, Voltaire urged, “Go on, brave Diderot, intrepid d’Alembert. Fall upon the knaves, destroy their empty declamations, their miserable sophistries, their historical lies, their contradictions and absurdities beyond number.”
One of those closely watching these developments was the new empress of Russia. Soon after her accession, and aware of the influence of Diderot and d’Alembert, Catherine set about winning their support. In August 1762, two months after she took the throne, the difficulties of publishing the
