Among Handel's seventeen English oratorios, Theodora (1750) is unique. The story is not taken from the Bible, it is set in the Christian era, there is no national triumph and it does not end in joy. At the end, the hero and heroine are dead, the community with which the audience identifies is in mortal danger, and the final chorus is in a minor key. As a musical drama, it is the direct ancestor of Dialogues des Carmélites. At the age of 65, Handel produced a work that was too radical and complex for most of his audience. Today, Theodora is regarded as a benchmark "thinking person’s opera", both deeply stimulating and powerfully moving.
