 Its incredible popularity prompted Offenbach to follow up with more operettas such as "La belle Hélène" (1864) and "La Vie parisienne" (1866) as well as the more serious "Les contes d'Hoffmann" (1881).Opera flourished in late nineteenth-century Paris and many works of the period went on to gain international renown.These include "Mignon" (1866) and "Hamlet" (1868) by Ambroise Thomas; "Samson et Dalila" (1877, in the "Opéra" 's new home, the Palais Garnier) by Camille Saint-Saëns; "Lakmé" (1883) by Léo Delibes; and "Le roi d'Ys" (1888) by Édouard Lalo.
