This popular prayer to the Blessed Virgin Mary was composed by St. Bernard of Clairvaux (1090–1153).  Its title is the first word of the Latin version.

The prayer was made popular through the efforts of a French priest, Claude Berrnard, early in the seventeen century.

This is a great prayer, and is as follows:  “Remember, O most gracious Virgin Mary, that never was it known that anyone who fled to thy protection, implored thy help or sought thy intercession, was left unaided.  Inspired with this confidence, I fly unto thee, O Virgin of virgins and Mother: to thee do I come, before thee I stand, sinful and sorrowful; O Mother of the Word Incarnate, despise not my petitions, but in thy mercy hear and answer me.  Amen.” (7:20)
