The Chaplet of the Divine Mercy is a Roman Catholic evotion based on the visions of Polish nun and canonized saint, Sister Faustina Kowalska (1905-1938), known as the "Apostle of Mercy". The chaplet is often said as a rosary-based prayer with the same set of rosary beads used for reciting the Holy Rosary or the Chaplet of Holy Wounds. However, the chaplet may also be said without beads, usually by counting prayers on the fingertips.
