La Sylphide was the first ballet for which point shoes were worn and might be thought of as the first ballet of the romantic era. Teh ballet has been in continuous production ever since it was created in 1832, however the choreography by Marie Taglione’s father was lost. In 1972, a new version of La Sylphide, based on the Taglioni version, was choreographed and staged by Pierre Lacotte for the Paris Opera Ballet. Lacotte’s choreography is based on prints, notes, drawings, and archival materials from the era of the ballet’s premiere. This is the version, with its fascinating stagecraft and flying fairies is the one I recommend
Aurelie danced it beautifully in 2004, and the video of this performance can be viewed on youtube. (buying the video gives you better clarity)
Another beautiful version was the one with Evdokimova who danced the role with the London festival Ballet in the 1970s. Evdokimova was famous for this role. I think the acting of the witches in the British version is also better. The video on you tube of this production is poor quality, even so it is well worth the watching if you are real enthusiast.
This is the full ballet danced by Aurelie Dupont of the Paris Opera
