This ballet is the namesake of a 1997 Boris Eifman production that doubles as a biography of dancer Olga Spessivtseva (SPEH-siv-TSAY-vuh). Pressure from Nathalie Fitzjames resulted in the addition of this ballet's traditional “peasant pas de deux.” Lines of dancers enter from both sides of the stage and hop towards each other en arabesque in a waltz from its ballet blanc second act that is performed by the followers of (*) Queen (10[1])Myrtha. Carlotta Grisi became a (10[1])star after the premiere of this ballet, whose first (10[1])act ends with a mad scene prompted (10[1])by Hilarion's (10[1])revelation that the title character's suitor Loys is actually Duke Albrecht. For 10 (10[1])points, name this Romantic ballet composed by Adolphe Adam, whose title character's spirit is raised from her grave by the Wilis (VEE-leez). ■END■
