Giuditta is based on the Biblical story of Judith, a beautiful Israelite widow who insinuates herself within the camp of the conquering Assyrian tribe and deceives their general, Holofernes, before decapitating him and carrying off his head in triumph. This is the second version of the oratorio, known as the Cambridge version after the location of the manuscript when it was turned up in modern times. Scarlatti had considered the original version, composed for Rome in 1693, to be his finest oratorio. This is no mean assessment from the composer of masterworks which have been more celebrated in our own time such as La Maddalena, for their expressive pathos and superbly grateful vocal lines.
