«EN CLARA VOX REDARQUIT». – Hymn of praise for the season of Advent, by an unknown author; it appears in manuscripts from the 10th century.
At dawn of the day that is born, a clear voice warns us to drive away the phantoms, because Christ is drawing near. This new light will have the power to dispel all darkness, and when, at the end of the world, it appears for the second time, it will envelop us for all eternity.
