From the Dominican Breviary (antiphon to the Psalms at First Vespers):
This is the Queen of virgins, the virgin, beautiful as a rose, who bore the king. Mother of God, through whom we gain God and man, gracious Virgin, intercede for us all.
From the "The Martyrology of the Sacred Order of Friars Preachers" (Tr. by Rev. W. R. Bonniwell, O. P., The Newman Press - Westminster, Maryland, 1955):
The Commemoration of Our Lady of Victory, which Pope Plus V instituted to be made annually, on account of the famous victory gained on this very day by the Christians in a naval battle against the Turks, by the assistance of the same Mother of God. However, Gregory XIII decreed that for the same victory there should be celebrated on the first Sunday of this month the annual solemnity of the Rosary of the Most Blessed Virgin.
From “Short Lives of the Dominican Saints” (London, Kegan Paul, Trench, and Trübner & Co., Ltd., 1901):
The devotion of the Holy Rosary is the great treasure bequeathed by our holy Father, Saint Dominic, to his Order and to the Church. A certain obscurity hangs over its origin, but a widespread tradition asserts that it was revealed to teh Holy Patriarch by our Blessed Lady herself during this labors in Languedoc for the conversion of the Albigensian heretics, and that by preaching his devotion he gathered an immense harvest of souls. Pope Clement VIII declares that Saint Dominic first established the Confraternity of the Holy Rosary in the Church of Saint Sixtus in Rome, and he is know to have established it also at Palencia in Spain. There can be no doubt that the use of the Hail Mary as a popular devotion dates from the beginning of the thirteenth century; though it is impossible to determine whether the preaching of the Rosary spread the more universal use of the Angelic Salutation, or whether it was the increasing love and popularity of that prayer which moved the holy Patriarch to adopt it.
During the fifteenth century, however, which was a period of general religious declension, the "Roses of Mary," as they had been popularly called, fell into partial oblivion and neglect, until, towards the close of the century, they were revived by the preaching of the celebrated Dominican, Blessed Alan de la Roche, a Briton by birth. It is interesting to be able to record that in England at least the Rosary never fell into disuse, but enjoyed undiminished popularity all through the thirteenth, fourteenth, and fifteenth centuries; and that Henry VI prescribed that the scholars of Eton College, founded by him in the year 1440, should daily recite "the complete Psalter of the Blessed Virgin, consisting of a Credo, fifteen Paters, one hundred and fifty Ave Marias". It is of course beyond question that the children of Saint Patrick, ever devout to our Blessed Lad, were ever faithful to the devotion of the Rosary; and that in the evil days, as they would rather have given their lives than deny God and His Holy Mother, so they would rather have shed their blood than part with their beads.
The solemnity which we celebrate on the first Sunday of October [now October 7], was established in thanksgiving for the great naval victory gained by teh Christians over the Turks at Lepanto on Sunday, October 7, A.D. 1571. On that memorable day, all the Confraternities of the Rosary in Rome had assembled in the Dominican Church of the Minerva to offer their devotions for a blessing on the Christian arms through the intercession of Mary. The Pope, Saint Pius V, himself a Friar Preacher, had attended the procession; and, on his return to the Vatican, God was pleased to reveal to him that the Queen of the Holy Rosary had even in that hour obtained a glorious victory for the Christian fleet. In testimony of his gratitude, the Holy Pontiff decreed that the 7th of October should henceforth be kept as the Feast of our Lady of Victories. But Gregory XIII, admiring the modesty of his
In our own day, the devotion of the Holy Rosary has received a fresh impulse from the Encyclical Letters published year after year by our Holy Father, Leo XIII, whom we may call "the Pope of the Rosary," and who has constantly urged on the faithful the use of this salutary devotion, both as an excellent means of personal sanctification, an efficacious form of intercessory prayer, and a powerful weapon against the enemies of the Church. His Holiness has likewise extended to the universal Church the practice, hitherto confined to the Dominican Order, of consecrating the whole month of October in a special manner to our Lady of the Rosary.
O God, whose only begotten Son by his life, death, and resurrection has purchased for us the rewards of eternal salvation, grant, we beseech you, that meditating upon these mysteries of the most holy Rosary of the blessed Virgin Mary, we may imitate what they contain and obtain what they promise. Through the same...
