Nuper rosarum flores information

Nuper rosarum flores ("Recently Flowers of Roses/The Rose Blossoms Recently"), is a motet composed by Guillaume Dufay for the 25 March 1436 consecration of the Florence Cathedral, on the occasion of the completion of the dome built under the instructions of Filippo Brunelleschi. Technically, the dome itself was not finished until five months later, at which time a separate consecration was celebrated by Benozzo Federighi, the bishop of Fiesole, substituting for the newly appointed archbishop of Florence, Cardinal Vitelleschi.^[1] The work has "come to be treated as an icon in the history of Western musical culture".^[2]

It has been argued that the motet presents homographic tenors and is therefore not an isorhythmic motet as often presented, since there are no isorhythms in its compositional proceedings.^[3] Regardless, the motet is striking for its synthesis of the older isorhythmic style and the new contrapuntal style that Dufay himself would explore further in the coming decades, as would successors such as Ockeghem and Josquin des Prez.^{[citation needed]}

The title of the piece stems from the name of the cathedral itself: Santa Maria del Fiore, or St. Mary of the Flower. The opening lines of Dufay's text refers to Pope Eugene IV's gift to the cathedral, and to the city of Florence, of a golden rose to decorate the high altar—a gift made the week before the dedication.^[4]
