According to legend, St. Dominic was given this prayer by the Virgin Mary, instructing him to use it as an aid against the Albigensian heresy in the beginning of the 13th century. History, however, indicates a murky beginning that most likely started in the Middle Ages where lay monks and laypeople who didn’t know how to read prayed 150 “Our Fathers” instead of psalms for the Divine Office, keeping count on a string of beads. Marian devotion grew in the 12th century and eventually substituted “Our Fathers” with “Hail Marys.” The 150 prayers were then divided into 15 decades by Dominican friar Henry Kalkar in the 14th century, each meditating on an event of the lives of Jesus and Mary. Another Dominican, Alanus de Rupe, divided them further into the mysteries of the history of salvation—joyful, sorrowful, and glorious— in the 15th century and formed the “Psalter of the Blessed Virgin.” Pope St. Pius V officially approved the rosary as we know it in 1569 in the papal bull Consueverunt Romani Pontifices.
In the 19th century, Pope Leo XIII encouraged Catholics to constantly use this devotion and wrote 12 encyclicals on the rosary. Perhaps most notably, the rosary was a favorite prayer of St. John Paul II, who wrote the apostolic letter Rosarium Virginis Mariae (The Rosary of the Virgin Mary) in 2002 and added the luminous mysteries to the rosary.
The Battle of Lepanto in 1571 was a naval battle between the Ottoman empire and Christian forces (Venice, Spain, and the pope) during the Ottomans’ attempt to acquire Cyprus. Pope St. Pius V asked all Christians to pray the rosary, and the battle was won by Christian forces. Attributing the victory to the prayer of the Blessed Virgin, he established a new feast: Our Lady of Victory, which became the feast of Our Lady of the Rosary.
There are many ways to celebrate the rosary this month, but here are a few to get you started.
