In 1625, King Louis XIII of France presented papal envoy Cardinal Francesco Barberini with a series of seven tapestries, designed by Peter Paul Rubens and woven in Paris, on the life of Constantine, the first Roman emperor to convert to Christianity. This tumultuous scene from the series represents the battle of the Milvian Bridge near Rome in A.D. 312, when Constantine defeated Maxentius to become sole emperor in the West. Upon returning to Rome, Cardinal Barberini established his own tapestry works and commissioned Pietro da Corona to design additional tapestries for the Constantine series. Both Rubens and Cortona were great masters of the Baroque, a dynamic art ideally suited for just such large-scale, complicated narratives as the Constantine story. The Museum's thirteen Constantine tapestries form the Barberini collection, reunited by the Kress Foundation in the 1950s, permit a rare comprehensive demonstration of the Baroque style and form an appropriately sumptuous decoration for the second-floor balcony of the Museum's Great Stair Hall.
