Ave Maria Caelorum, performed by the Christendom College Choir & Schola Gregoriana

Ave Regina Caelorum is one of four Marian antiphons, with following versicles and prayers, traditionally said or sung after each of the canonical hours of the Liturgy of the Hours. The prayer is used especially after Compline, the final canonical hour of prayer before going to sleep. It is said from the Feast of the Presentation (February 2) through Wednesday of Holy Week. The origins of the prayer are unknown but it can be found included in a twelfth century manuscript.

The prayer is associated with indulgences and is listed as Ave Regina Coelorum in the Raccolta book of indulgenced prayers.

Translation:

Hail, O Queen of Heaven enthroned.
Hail, by angels mistress owned.
Root of Jesse, Gate of Morn
Whence the world's true light was born:
Glorious Virgin, Joy to thee,
Loveliest whom in heaven they see;
Fairest thou, where all are fair,
Plead with Christ our souls to spare.
