In October 1672, a highly select audience in Moscow witnessed the court's first theatrical production, a setting of Artakserksovo deistvo (The Play of Ahasuerus) based on the biblical story of Esther. A month later, in contrast, Parisians would witness the escalating rivalry between Molière and Lully—as the former continued to capitalize on their tragédie-ballet, Psyché (with Lully's music), while the latter prepared to launch his first French opera, Les Fêtes de l'Amour et de Bacchus (with Molière's lyrics).1 At first glance there would seem to be little connection between the fledgling Muscovite theatre at Tsar Aleksei Mikhailovich's court, which in the event was to be closed down at his death only four years later, and the public theatres of Paris with their lyrical offerings of comédies-ballets, tragédies-ballets and, most recently, pastoral opera. Yet the two are linked in many ways, some subtle and some obvious, and the influences are both mutual and unexpected.
