I penitenti al sepolcro del redentore (The penitents at the tomb of the redeemer), ZWV 63, is an oratorio by Jan Dismas Zelenka, commissioned and first composed for a performance on Good Friday, March 30 1736, for his employer Augustus III, in Dresden. The work departing from the usual canon of a setting of the text of one of the Gospels, being instead a poem focusing on the meaning of Christ's sacrifice, is unusual in this aspect. The work survives as a manuscript in the Saxon State Library in Dresden, and has been recorded by various modern artists.
