Christus am Ölberge (in English, Christ on the Mount of Olives), Op. 85, is an oratorio by Ludwig van Beethoven portraying the emotional turmoil of Jesus in the garden of Gethsemane prior to his crucifixion. It was begun in the fall of 1802, soon after his completion of the Heiligenstadt Testament, as indicated by evidence in the Wielhorsky sketchbook. The libretto in German is by the poet Franz Xaver Huber, editor of the Wiener Zeitung, with whom Beethoven worked closely. It was written in a very short period; in a letter to Breitkopf & Härtel written shortly after the oratorio's completion, Beethoven spoke of having written it in "a few weeks", although he later claimed that the piece required no more than 14 days to complete. It was first performed on April 5, 1803 at the Theater an der Wien in Vienna; in 1811, it was revised by Beethoven for publication by Breitkopf & Härtel. The 10 years that passed between the composition of the work and its publication resulted in its being assigned a relatively high opus number.
The work is a dramatic oratorio rather than a religious choral Mass or a dramatic opera, and is considered a much more humanistic portrayal of the Christ passion than other settings, such as those by Bach. It concludes at the point of Jesus personally accepting his fate, placing the emphasis on his own decision rather than the later Crucifixion or Resurrection. The oratorio is scored for soprano, tenor, and bass soloists, with standard SATB chorus and symphony orchestra. The tenor sings as Jesus, with the soprano as a seraph (angel) and the bass as Peter. A complete performance lasts approximately 50 minutes.
