Saint Dominic, the Albigensian heretics and the Most Holy Rosary of Our Lady

 When the heresy of the Albigenses was making head against God in the County of Toulouse, and striking deeper roots every day, the holy Dominic, who had but just laid the foundations of the Order of Friars Preachers, threw his whole strength into the travail of plucking these blasphemies up. That he might be fitter for the work, he cried for help with his whole soul to that Blessed Maiden, whose glory the falsehoods of the heretics so insolently assailed, and to whom it hath been granted to trample down every heresy throughout the whole earth. It is said that he had from her a word, bidding him preach up the saying of the Rosary among the people, as a strong help against heresy and sin, and it is wonderful with how stout an heart and how good a success he did the work laid upon him. This Rose-garden (or Rosary) is a certain form of prayer, wherein we say one-hundred-and-fifty times the salutation of the Angel, and the Lord's Prayer between every ten times, and, each of the fifteen times that we say the Lord's Prayer, and repeat tenfold the salutation, think of one of fifteen great events in the history of our Redemption. From that time forth this form of godly prayer was extraordinarily spread about by holy Dominic, and waxed common. That this same Dominic was the founder and prime mover thereof hath been said by Popes in diverse letters of the Apostolic See.
