It was on this day 288 years ago that the fabled French actress Adrienne Lecouvreur died in Paris.
During the evening the Chevalier said, insultingly and several times: ‘M. de Voltaire, M. Arouet or whatever you call yourself.’ In the end, Voltaire lost his temper and said that he was the first of his name while the Chevalier was the last of his. This stung Rohan-Chabot on the raw. His grandmother had been the only child of the Duc de Rohan, an ancient family descended from the Kings of Brittany. She had married a Chabot; the family was no longer Rohan at all. The Chevalier, furious, lifted his cane and and said that such an insult could only be wiped out by a good hiding. Voltaire put his hand to his sword; Mlle Lecouvreur tactfully fainted away and the Chevalier left the box. (pp 43-44)
