Giselle
In an 1841 news article announcing the first performance of Giselle, Théophile Gautier recorded his part in the creation of the ballet. He had read Heinrich Heine's description of the Wilis in De l'Allemagne, and thought these evil spirits would make a "pretty ballet". He planned their story for Act 2, and settled upon a verse by Victor Hugo called "Fantômes" to provide the inspiration for Act 1. This verse is about a beautiful 15 year old Spanish girl who loves to dance. She becomes too warm at a ball, and dies of a chill in the cool morning.
