On 6 June 1920, a work premièred at the Paris Opéra and, unlike others preceding it that season, met with general approbation in the press. Despite reservations, newspapers as well as political and musical journals pronounced the opera sincere, deeply religious, an ‘oeuvre de foi’. The composer–librettist, Vincent d'Indy, must have been both pleased and perplexed by such praise, for he had originally conceived the work as a trenchant political critique. As planned in 1903, the opera was to show, in d'Indy's words, ‘the nauseating Judeo-Dreyfusard influence’ within a legend that accommodated this message.
