"O come, O come, Emmanuel" (Latin: "Veni, veni, Emmanuel") is a Christian hymn for Advent and Christmas. The text was originally written in Latin. It is a metrical paraphrase of the O Antiphons, a series of plainchant antiphons attached to the Magnificat at Vespers over the final days before Christmas. The hymn has its origins over 1,200 years ago in monastic life in the 8th or 9th century. Seven days before Christmas Eve monasteries would sing the “O antiphons” in anticipation of Christmas Eve when the eighth antiphon, “O Virgo virginum” (“O Virgin of virgins”) would be sung before and after Mary’s canticle, the Magnificat (Luke 1:46b-55). The Latin metrical form of the hymn was composed as early as the 12th century.
