The poem of Nicolas Le Digne, poet of the XVIth century,is dedicated to the Virgin Mary. With an extreme delicacy, the tribute comes through the image of the rose.In a flowery language, the poet evokes the themes of beauty, the "life of the soul", and that of "cheerful revival" ; His lyricism, intimistic, is radiant of light.The anthem begins with a ritornello in the organ, intended to evoke the opening of the petals of the rose while installing a climate of mystery and meditation. The voices will be most of the time a cappella, the destitution of the music always serving emotion in a mixture of moose, worship and tenderness.
