This new CD presents the world premiere recording of Michael Haydn's oratorio "Emperor Constantine I Campaign and Victory", performed here by Gyorgy Vashegyi, the Orfeo Orchestra and Purcell Choir. The score of his oratorio "Emperor Constantine I Campaign and Victory" was long considered lost, but was only recently rediscovered in the Esterhzy Music Archive in Budapest and is now being presented as the first time on sound recording. The work was written as an oratorio for Lent and first performed in Salzburg in 1762. The oratorio tells the story of Emperor Constantine I, who received a heavenly sign at the Battle of the Milvinian Bridge in Rome in 312, thereby achieving victory and converting to the Christian faith. Various allegorical figures such asFaith, Fortitude, Faintheartedness or Theology polemicise about Christian doctrine and faith until Constantine's victory becomes a certain fact.
