St. Dominic and Mary's Psalter

In the traditional calendar, today, August 4, is the feast day of St. Dominic de Guzman, founder of the great Order of Preachers and beloved for his popularization of the Marian Psalter (Holy Rosary).

According to the Fish Eaters website, "St. Dominic de Guzman popularized the Marian Psalter in the form we have it today (150 Aves with a Pater after each 10) when Our Lady encouraged him to pray it that way in response to the Albigensian heresy."
