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.
