The Chaplet of Saint Michael the Archangel, also called the Rosary of the Angels, is a chaplet approved by Pope Pius IX in 1851.

Antónia d'Astónaco

Antónia d'Astónaco was a Portuguese Carmelite nun who reported a private revelation by Saint Michael the Archangel in 1750. Sometime in the 1750s, d'Astónaco said that the Archangel Michael had indicated in an apparition that he would like to be honored, and God glorified, by the praying of nine special invocations. These nine invocations correspond to invocations to the nine choirs of angels and origins the Chaplet of Saint Michael. The prayers were approved by Pope Pius IX in 1851.

Chaplet

The prayers are generally prayed with a chaplet, counting the prayers with it as one would do with a rosary. For those who would recite the Chaplet daily, Saint Michael reportedly promised his continual assistance and that of all the holy angels during life. Praying the chaplet is also believed gradually to defeat demons and gain a pure heart, thus delivering the petitioner from Purgatory. These blessings extend to the direct family. 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. (Say one Our Father and three Hail Marys after each of the following nine salutations in honor of the nine Choirs of Angels)

Promises

Saint Michael purportedly promised to those who recite these nine salutations, every day:

Indulgences

The indulgences granted by Pope Pius IX were superseded by the 1968 Enchiridion Indulgentiarum. Although the chaplet is not specifically mentioned in either the Enchiridion or the later Directory on Popular Piety and the Liturgy, the Enchiridion provides:
