(Beethoven: Fidelio). Ten. A Spanish nobleman, husband of Leonore. Secretly imprisoned by his enemy Pizarro. His wife Leonore dresses as a man (Fidelio) to work at the prison as the gaoler's assistant. She confirms that her husband is the special prisoner being held in a dungeon, whose grave she helps to dig. She manages to give him a little water and bread, but Florestan does not recognize her. She prevents Pizarro stabbing her husband just as the King's Minister arrives to free him and his fellow‐prisoners. Aria: Gott! Welch’ Dunkel hier! (‘God! How dark it is here!’); duet (with Leonore): O namenlose Freude! (‘Oh, nameless joy!’). The role of Florestan demands great vocal stamina from a tenor—the difficult tessitura almost requires a Heldentenor. Famous Florestans have included Enrico Tamberlik, Julius Patzak, Torsten Ralf, Jan Peerce, Wolfgang Windgassen, Ernst Haefliger, Jon Vickers, James McCracken, and Anton de Ridder. Created (1805) by Friedrich Christan Demmer.
