<P> From the 16th to the early 20th century , the structure of the rosary remained essentially unchanged . There were 15 mysteries , one for each of the 15 decades . In the 20th century the addition of the Fatima Prayer to the end of each decade became popular . After Vatican Council II , Msgr . Annibale Bugnini , architect of the liturgical reform , proposed further changes to the structure of the Rosary , but Pope Paul VI refused to implement the proposal on the grounds that changing such a well - established and popular devotion would unsettle the piety of the faithful and show a lack of reverence for an ancient practice . There were thus no other changes until 2002 when John Paul II instituted five new Luminous Mysteries . In the 17th century , the Rosary began to appear as an element in key pieces of Roman Catholic Marian art . Key examples include Murrillo 's Madonna with the Rosary at the Museo del Prado in Spain , and the statue of Madonna with Rosary at the church of San Nazaro Maggiore in Milan . Several Roman Catholic Marian churches around the world have also been named after the rosary , e.g. Our Lady of the Rosary Basilica , in Rosario Argentina , the Rosary Basilica in Lourdes and Nossa Senhora do Rosário in Porto Alegre , Brazil . </P>
