Diana von Solange is an opera by the German prince Ernst II of Saxe-Coburg-Gotha, an amateur composer. It was premiered in 1858. In 1859, Franz Liszt wrote an orchestral Festmarsch nach Motiven von E. H. z. S-C-G, S.116, based on themes from Diana von Solange (E. H. z. S-C-G was short for Ernst Herzog zu Sachsen-Coburg-Gotha). Despite the opera's poor reception, Andreas Dippel was singled out for praise by numerous critics; this, coupled with his other successes during the season, led to his being retained on the company's roster for the following year.
