'Pas de Quatre' was originally choreographed by Jules Perrot in 1845 to music by Cesare Pugni.
The ballet caused a sensation with both critics and public, when it premiered in London in July of 1845.
One reason for its success was that it brought together four of the greatest ballerinas of the time. In order of appearance in the work, the ballerinas were Lucile Grahn, Carlotta Grisi, Fanny Cerrito, and Marie Taglioni, with this order being according to age. This cast only performed four times together.
Fanny Elssler, the fifth great Romantic ballerina of the time, was invited to take part but declined the offer.
Iskander21024 has very kindly identified the four ballerinas here:
"The first soloist - Nina Gruzdeva-Sanina, the second one - Irina Kolpakova, the third one - Olga Moiseeva, the fourth one - Tatyana Udalenkova."
And also tells:
"As Udalenkova told me they had got this 'Pas de Quatre' from A. Dolin during the tour of the Kirov ballet of Canada and filmed in the old TV studio in Leningrad."
Thanks so much for your help Iskander21024 -- it is much appreciated.
Enjoy!
