Two ballets with such stories caused great excitement in Paris in the 1830s. In November 1831, Meyerbeer's opera "Robert le diable" had its first performance. It included a short ballet called "The Ballet of the Nuns". In this little ballet, dead nuns rise from their graves. They dance in the moonlight. The public loved this ballet. In March 1832, the ballet "La Sylphide" was performed. This ballet is about a beautiful sylph (fairy). She loves James, a young Scotsman. Tragedy occurs. James accidentally kills the sylph.
