"Miracle of the Monk and Roses": Medieval Origin of the Rosary

There is an ancient Medieval account of the origin of the The Most Holy Rosary of the Most Blessed Virgin Mary as given directly to a monk by Our Blessed Mother Mary called "The Miracle of the Monk and Roses."

Bystanders — actually robbers! — saw a young monk, stopping to rest in his journey, kneel down in the road and begin reciting “Ave, Maria...” As each prayer dropped from the monk’s lips, it turned into a rose, which was gathered up by the Virgin Mary standing nearby (the monk evidently didn’t see her, but the robbers did). The Virgin showed her pleasure at the gift of prayers by weaving the roses into a garland for her head. The robbers immediately repented and hastened to a priest to confess their sins, became monks, and, after a long and joyful lives in the monastic life died holy deaths!

The Miracle of the Monk and Roses: Bohun Hours, fol. 20r

The manuscript is the Bohun Hours, Royal Library, Copenhagen, MS Thott 547 4°, made in England around 1370–1387. On fol. 20r, in the lower border, is a three-part illumination explicitly identified by the manuscript catalogue as “The Miracle of the Monk and Roses.”

And, importantly, the Royal Library itself has the folio online:

Royal Library — Thott 547 4°, folio 20 recto

The catalogue gives the three scenes:

1. Left: A young monk kneels before an image of the Virgin and places a wreath of flowers on her head.
2. Center: The monk has become distressed because the season of roses has passed and he can no longer make his customary rose wreaths.
3. Right: This is the scene you are looking for. The monk kneels before the crowned Virgin, who holds a wreath; two or three robbers are shown in the adjacent grove, pointing toward the miraculous scene. Two horses and additional figures are also present.

The remarkable thing is that this isn't merely an image that happens to resemble the story. The scholarly catalogue calls the sequence “The Miracle of the Monk and Roses” and explicitly identifies the figures at the right as robbers.

But there is an interesting difference from your wording

The illumination does not seem to show the individual roses visibly coming out of the monk's mouth. Instead, the artist has compressed the miracle into the final scene: the monk is kneeling before Mary with the completed wreath, while the robbers stand off to the side witnessing it.

That may actually tell us something about medieval iconography: the artist apparently assumed that the viewer already knew the narrative and represented the result of the miracle, rather than laboriously depicting every Ave Maria becoming a rose.

There is also strong scholarly evidence that this particular story was indeed transmitted in versions involving a monk and robbers. A study of the medieval tradition specifically says that the robbers “perceive the Virgin gathering roses from the brother’s mouth and weaving them into garlands”, and cites the 1454 Mainz manuscript Unser Frauwen Rosengertlin as an early witness.

And there is an earlier textual witness

The Oxford database identifies the story as “Aves Seen as Roses,” from Jean Mielot's Miracles de Nostre Dame, with the rubric:

Dun jeusne religieulx qui par deuocion faisoit tous les jours des roses vng chappeau de roses...

“A young religious who out of devotion made every day a chaplet of roses...”

So we've now got a pretty solid chain:

medieval text → monk → Ave Marias → roses → Virgin → rose garland → robbers witness the miracle → medieval manuscript illumination actually depicting the monk, Virgin, garland, and robbers.
