This article aims at situating Iphigénie en Tauride within Nicolas-François Guillard’s work. His first success did indeed influence the conception and reception of his other “tragédies lyriques”, which were all composed after this model, according to the principle based on the suppression of ballets and amorous subplots. Iphigénie en Tauride was the apex of Gluck’s career and the beginning of Guillard’s, who, as early as the first performance, had made his mark as a librettist.
