Little Crown of Twelve Stars

History:

An ancient devotion of the Order of Our Lady of Mercy based on the Book of Revelation 12:1.
St. John, the beloved disciple of Jesus and Mary, was privileged to behold a wonderful sign in Heaven: "A woman clothed with the sun, and the moon was under her feet, and upon her head a crown of twelve stars." This gave rise to the Crown of Twelve Stars devotion which Heaven has blessed with countless favors. St. John Berchmans made it his daily favorite.
This chaplet is prayed to honor each of those twelve stars as they symbolize her motherhood and queenship over all Israel, the twelve stars representing the 12 Tribes and the 12 Apostles. This devotion consists of 12 Aves — one for each star — broken up into 3 groups, each group representing an aspect of Mary's virtues: excellence, power, and goodness.
An indulgence of 3 years. A plenary indulgence on the usual conditions, if this devotion is repeated daily for a month.

Medals/Beads:

The chaplet consists in a medal, five Our Father beads and three sets of four beads each where the Hail Mary is prayed.  Each group begins with an Our Father, and ends with a Glory Be. The entire Crown, then, is the praying of the following arrangement of prayers three times: 1 Our Father, 4 Hail Marys, 1 Glory Be.
