Paul Westermeyer Let the People Sing: Hymn Tunes in Perspective 2005 Page 61 "Advent Ambrose's Advent hymn "Veni redemptor gentium," discussed in Chapter II, was well known in Germany. Luther translated it into German. Then he, or possibly Walter, simplified its chant tune, VENI REDEMPTOR GENTIUM, into the chorale tune that takes its German name from Luther's translation, NUN KOMM, DER HEIDEN HEILAND." For a comparison of the chorale tune to the original chant melody, see "Chorale Melodies used in Bach's Vocal Works: Nun komm, der Heiden Heiland," Bach Cantatas Website, accessed 2014-08-27.
