Saint Bridget prayed for a long time to know how many blows Jesus Christ suffered during His terrible Passion. Rewarding her patience, one day He appeared to her and said, "I received 5480 blows upon My Body. If you wish to honor them in some way, recite fifteen Our Fathers and fifteen Hail Marys with the following Prayers, which I Myself shall teach you, for an entire year. When the year is finished, you will have honored each of My Wounds." The prayers became known as the Fifteen O's, because in the original Latin, each prayer began with the words O Jesu, O Rex, or O Domine Jesu Christe. Some have questioned whether Saint Bridget is in fact their author; Eamon Duffy reports that the prayers probably originated in England, in the devotional circles that surrounded Richard Rolle or the English Brigittines. Whatever their origin, the prayers were quite widely circulated in the late Middle Ages.
