Redemptoris mater quae pervia coeli
Porta porta manes, et Stella maris
Stella maris succure cadenti
Surgere qui curat populo tu quae genuisti
Natura mirante tuum sanctum genitorem
tuum sanctum genitorem
tuum sanctum genitorem genitorem
Virgo prius ac posterius
Virgo prius ac posterius
Gabrielis ab ore
Sumens illud illud Ave
Sumens illud illud Ave pecatorum
rum miserere peccato

Alma Redemptoris Mater quae pervia coeli. [Blessed Virgin Mary.] One of four Antiphons to the B. V. M. used at the termination of the Offices, the remaining three being the Ave Regina, the Regina coeli, and the Salve Regina. It is ascribed to Hermannus Contractus, who died 1054. In Daniel, ii. p. 318, the text is given in full, together with a note setting forth its use, with readings from a Munich manuscript probably of the 13th century. Concerning its use we may add from Daniel and other authorities:—
That it is appointed to be said at the end of Compline from the Saturday before the first Sunday in Advent to the 2nd of February, inclusively, and that in the old Franciscan Breviary, dated 1497, it is to be sung till Quinquagesima Sunday. In the Breviaries of Rome, Paris, Lyons, &c, it is to be said at the end of Compline from the 1st Vespers of the 1st Sunday in Advent to the Feast of the Purification, inclusively; also after Lauds during this time, if the choir where the office is recited be left; if Prime, or other Hours, shall be said immediately after Lauds, then this Antiphon should be used at the end, once for all. Should the Feast of the Purification be transferred, on account of some privileged day (as Septuagesima Sunday) falling on the same time, yet the Alma Redemptoris Mater is not to be continued beyond Feb. 2, according to decrees of the Roman Congregation of Rites, 1681,1693,1705.
How well this Antiphon was known in England in the Middle Ages we may judge from the use which Chaucer made of it in his Prioress's Tale, where the whole story is associated therewith. The Poet then explains the way in which the child mastered the Antiphon, together with the music to which it was set; and describes his singing it in the public streets, his murder by the Jews for so doing, and the subsequent results.
