Originally a wreath worn on the head, the name came to be used for beads strung together, especially beads upon which prayers are counted as they are recited. It is most frequently used to designate a string of 55 beads, a third of the Rosary, upon which are recited 50 Aves and 5 Paters. The term is also applied to strings of fewer beads used for reciting various prayers and aspirations in honor of Our Lord, the Holy Eucharist, etc., as well as for the prayers recited.
It is an emblem in art associated with Saint Dominic and Saint Alphonsus Liguori, referring either to their devotion to the Rosary, or indicating a special distinction.
