when were the luminous mysteries of the rosary introduced
Rosary From the 16th to the early 20th century, the structure of the rosary remained essentially unchanged.[23] There were 15 mysteries, one for each of the 15 decades. During the 20th century, the addition of the Fatima Prayer to the end of each decade became more common. There were no other changes until 2002, when John Paul II instituted five optional new Luminous Mysteries, although variations of these had already been proposed by the likes of St. Louis de Montfort and were implemented during the mid-20th Century by figures such as Patrick Peyton.

Rosary A standard fifteen Mysteries of the Rosary, based on the long-standing custom, was established by Pope Pius V in the 16th century, grouping the mysteries in three sets: the Joyful Mysteries, the Sorrowful Mysteries, and the Glorious Mysteries. In 2002 Pope John Paul II said that it is fitting that a new set of five be added, called the Luminous Mysteries, bringing the total number of mysteries to twenty, although he did not create these mysteries. They had been used by Holy Cross father Patrick Peyton, the "Rosary Priest" of the 20th Century.
