Giselle
Gautier thought Heine's Wilis and Hugo's fifteen year old Spanish girl would make a good ballet story. His first idea was to present an empty ballroom glittering with crystal and candlelight. The Wilis would cast a spell over the floor. Giselle and other dancers would enter and whirl through the room, unable to resist the spell to keep them dancing. Giselle would try to keep her lover from partnering other girls. The Queen of the Wilis would enter, lay her cold hand on Giselle's heart, and the girl would drop dead.
