Nine Rivers from Jordan is an opera in a prologue and three acts by composer Hugo Weisgall. The work uses an English libretto by Denis Johnston who derived the libretto from the book of the same title he wrote based on his experiences as a BBC radio reporter during World War II. The work premiered on October 9, 1968, at the New York City Opera. The opera musically, dramatically and symbolically attempts to deal with the unprecedented moral problems caused by the circumstances of the Second World War. The use of many different languages in the libretto, the rapid changes of scene and the geographical extent of the action mirror the universal involvement and confusion of those years. In the opera, actual happenings and imaginary events are juxtaposed.
