Madonna with the Blue Diadem is an oil painting on wood by Raphael and his pupil Gianfrancesco Penni that is held at the Louvre. Most likely completed in Rome in the 1510s, the painting features Mary symbolically lifting a veil over the sleeping Christ Child; Raphael had used the same theme in his Madonna of Loreto.Painting: Raphael and Gianfrancesco Penni
