The Star boys' singing procession has children and young people walking about with a movable star on a rod. The singing procession and the folk drama had its roots in an old medieval ecclesiastical play, centred on the Three Magi of the Christmas story in the Gospel of Matthew (2,1-28), appropriate to Epiphany. The liturgical drama developed from the 16th century on, as it was performed by cathedral schoolboys, to become a more secular mystery drama, containing also some ordinary Christmas songs and carols.
