Hours on the feast of the Assumption of Mary. The Ave Regina caelorum dates back in a different musical intonation to the 12th century. Today's version is slightly different from a 12th-century intonation. The Ave Regina caelorum has four parts: Ave, Salve, Gaude and Vale (in English: hail, rejoice, farewell). It was used for processions in honour of the Queen of Heaven. The Ave Regina caelorum received numerous musical versions, a famous one of which was composed in 1773 by Joseph Haydn.

Together with three other Marian anthems, it was incorporated in the Minorite Roman Curia Office, which the Franciscans soon popularized everywhere, and which by order of Pope Nicholas III (1277–1280) replaced all the older breviaries in the churches of Rome.

Catholicism employs the liturgical Latin phrase Ora Pro Nobis, meaning pray for us, and does not teach adherents to worship saints, but rather ask (asking is a form of prayer) those saints to pray for them.
