The scenario, initially in two acts, was fashioned from Russian and/or German folk tales[a] and tells the story of Odette, a princess turned into a swan by an evil sorcerer's curse. The choreographer of the original production was Julius Reisinger (Václav Reisinger). The ballet was premiered by the Bolshoi Ballet on 4 March [O.S. 20 February] 1877[1][2] at the Bolshoi Theatre in Moscow.
