Abstract

From its origins in the twelfth century, the rosary grew to become the most popular extraliturgical prayer of the Catholic church. Why this text—of all the medieval experiments in religious exercises—succeeded so dramatically has to do with the form of the text itself and with developments in popular religious piety. Like other medieval texts, the rosary was “written” collectively, that is, by accretion, experimentation, and revision, as users adapted it to evolving spiritual and practical ends. The most significant development in this process was the addition of “mysteries” to the prayer, which profoundly changed its character and created a new religious exercise uniquely suited to the needs of the lay faithful. Ultimately, the devotion shaped, and was shaped by, the demands of the laity for new, more individual and private forms of religious observance
