“Esmeralda” has been restored at the Musical Theater Each theater has its own “golden reserve,” or what it considers such, the works of a significant choreographer for the theater. The history of ballet flows and rolls, the dunes of time shimmer, and suddenly a man appears and presses such a mark in the sand that it remains for a very long time. At the Paris Opera it is Nureyev, at the English Royal Ballet it is Ashton and MacMillan, at the Bolshoi it is, of course, Grigorovich.
