Rosary: what did the older authorities say?

The Desert Fathers

Counted their prayers on knotted cords and pebbles in the fourth century, and the knotted prayer rope of the Orthodox East descends from them; the Latin West strung beads for the hundred and fifty psalms, and then for the Paternosters that the unlettered said in their place.

Saint Dominic

Received the rosary from the Virgin, in the tradition of his order, about 1208; the historians find no record of it before Alanus de Rupe, the Breton Dominican who founded the first Confraternities of the Rosary about 1470 and gave the devotion its form of fifteen mysteries.

Pius V

A Dominican himself, fixed the rosary in its present shape in 1569, and credited the victory of Lepanto in 1571 to it, instituting the feast of Our Lady of Victory, now Our Lady of the Rosary, on 7 October.

The Catholic Encyclopedia

The Catholic Encyclopedia sets out the Breviary's claim that Our Lady instructed St. Dominic “to preach the Rosary among the people as an antidote to heresy and sin,” and then the evidence against it: in all the Dominican writings “between 1220 and 1450 … no single verifiable passage has yet been produced which speaks of the Rosary as instituted by St. Dominic,” and the tradition converges on “the preaching of the Dominican Alan de Rupe about the years 1470-75,” a man “full of delusions” who “based his revelations on the imaginary testimony of writers that never existed.” Prayer-beads were called paternosters, and the makers, “paternosterers,” formed guilds by the thirteenth century; “Paternoster Row in London still preserves the memory of the street.” Beads that had touched a saint's relics “were often piously believed to be the instruments of miraculous power and healing virtue.”
