"The new genre was consolidated by Rossini's "Guillaume Tell" (1829) and Meyerbeer's "Robert le diable" (1831).Richard Wagner remarked, in his 1871 "Reminiscences of Auber", that the opera "whose very representation had brought [revolutions] about, was recognised as an obvious precursor of the July Revolution, and seldom has an artistic product stood in closer connection with a world-event."
