This melody dates to the Fifteenth century and was very popular in France. The original nine verse Latin hymn was written by Jean Tisserand, OFM (d. 1494). It was assigned to the celebration of Benediction of the Blessed Sacrament on Easter Sunday. While the triple alleluia was only to be sung at the beginning and ending, it has become a persistent refrain after each verse in most modern hymnals. The irregularity of the word stress may also have contributed to the great variety of rhythmic variations in the tune.
