The History of the Rosary

~ 900s ~ IRELAND AD ~ (800-900 AD) - Quoting Catholic Apologetics: 'Historians trace the origin of the Rosary back to ninth century Ireland. Today, as then, the 150 Psalms of the Bible, The Book of Psalms of King David, were an important form of monastic prayer. Monks and clergy recited or chanted the Psalms as a major source of hourly worship. People living near the monasteries realized the beauty of this devotion. But unable to read or memorize the lengthy Psalms, the people were unable to adapt this form of prayer for their use.'

FIRST STAGE
An Irish monk suggested to the people around the monastery that they might pray a series of 150 Our Fathers in place of the 150 Psalms. At first, pebbles were carried in a pouch to count the 150 Our Fathers; later ropes with 150 or 50 (1/3 of 150) knots were used. Eventually string with 50 pieces of wood was used.

SECOND STAGE
Next the Angelic Salutation (Lk 1:28) was added. St. Peter Damian (d. 1072) was the first to mention this form of prayer. Soon the Angelic Salutation replaced the 50 Our Fathers.

THIRD STAGE
Some medieval theologians considered the 150 Psalms to be veiled mysteries about the life, death and resurrection of Jesus. They began to compose "Psalters of Our Lord and Savior Jesus Christ" - 150 praises in honor of Jesus. Soon psalters devoted to 150 praises of Mary were composed. When a psalter of 150 praises in Mary's honor numbered 50 instead of 150, it was called a rosarium, or bouquet.
