The Chaplet of St. Michael the Archangel is a chaplet resulting from a private revelation by the Archangel Michael to the Portuguese Carmelite nun Antónia d'Astónaco. It was approved by Pope Pius IX in 1851 and was granted indulgences. The chaplet begins with an act of contrition. Then there are nine salutations, one for each choir of angels, each one followed by an Our Father and three Hail Marys. These are followed by four Our Fathers, honoring Saints Michael, Gabriel, Raphael and the Guardian Angel. The chaplet concludes with a prayer to Saint Michael.
