The Hymn dates from at least the 13th-Century, though it is possible that it is much older, with some sources ascribing its origin to Saint Gregory the Great († 604 A.D.), Saint Bernard of Clairvaux (1090-1153), or Saint Bonaventure (1221-1274).
It is a Mediaeval Latin poem, characterised by its accentual stress and its rhymed lines. The metre is trochaic. The poem describes the Day of Judgment, the Last Trumpet summoning Souls before the Throne of God, where the Saved will be Delivered and the Unsaved Cast into Eternal Flames.
The Hymn is best known from its use as a Sequence in the Roman Catholic Requiem Mass (Mass for the Dead or Funeral Mass). An English version is found in various Anglican Communion Service Books.
