Konrad Wallenrod
libretto by Zygmunt Sarnecki
Konrad Wallenrod is a Polish-language opera by Władysław Żeleński to a libretto by Zygmunt Sarnecki (1837-1922) and Władysław Noskowski (1841-1881) based on the epic poem Konrad Wallenrod (1828) by Adam Mickiewicz. The premiere was 1885 in Lviv, which was not prepared technically to create a grand opera on this scale. Notably at the premiere the elaborate harp part was played on the piano by Paderewski. A further staging in Krakow was not followed by a planned staging in Warsaw, which was stalled partly due to the Tsarist censor's concerns with the subject. Konrad Wallenrod was not performed in Warsaw till the 1930s.
