Occasional Oratorio, HWV 62

An Occasional Oratorio (HWV 62) is an oratorio by George Frideric Handel, based upon a libretto by Newburgh Hamilton after the poetry of John Milton and Edmund Spenser. The work was written in the midst of the Jacobite rising of 1745–1746, the attempt to overthrow Handel's patrons the Hanoverian monarchy under George II and replace them with a Stuart restoration under Charles Edward Stuart, "Bonnie Prince Charlie".The Occasional Oratorio is unique among Handel's works which he labelled "oratorio" in that it does not tell a story or contain elements of a drama, but was intended as a defiant and patriotic rallying piece. The Stuart armies, based in Scotland, had invaded England and got as far as Derby when the King's armies under the command of the King's son Prince William, Duke of Cumberland had driven them back to Scotland in December 1745. The fighting was at a hiatus due to winter weather and the Duke of Cumberland was in London in February 1746. Handel composed the Occasional Oratorio hastily in January and February 1746, "borrowing" and re-arranging some movements from previous compositions, and premiered it immediately on 14 February 1746 with Willem de Fesch, Élisabeth Duparc, Elisabetta de Gambarini, John Beard (tenor), and Thomas Reinhold at Covent Garden Theatre. It contains 44 movements split over three parts. Part One, generally speaking, concerns the miseries of war and the vengeance of a wrathful God, Part Two the blessings of peace, and Part Three a thanksgiving for victory. This was felt at the time by some to be premature as the rebels had not yet been defeated, Charles Jennens, Handel's friend and collaborator who wrote the text for Saul and others of Handel's oratorios called the piece "a triumph for a victory not yet gained." The festive four part overture, with trumpets and drums, is sometimes performed outside the context of the entire piece. The famous chorus "Prepare the Hymn" (a paraphrase of Psalm 81:1-2) is the 26th movement and appears in the second part. The second minuet from the Music for the Royal Fireworks was reused from this oratorio.
