Gianfrancesco Penni
Born in Florence to a family of weavers, Penni entered Raphael's workshop very early in his life, and collaborated with him on several works, including the famous Rooms of the Vatican Palace, as well as the frescoes of Villa Farnesina, both in Rome. Heinrich Wölfflin and some other writers credited him with the entire execution of the Raphael Cartoons, with Raphael only creating the initial design, though more recent writers believe Raphael did much of the work himself.
Creation of the World (Raphael)
Creation of the World is a mosaic composition in the dome of the Chigi Chapel in Santa Maria del Popolo, Rome, designed by Raphael. The chapel itself was designed by Raphael for his friend and patron, banker Agostino Chigi as a private chapel and family burial place. The dome was decorated with mosaics, a somewhat unusual and old-fashioned technique in the 16th century. Raphael's cartoons were executed by a Venetian craftsman, Luigi da Pace in 1516. The original cartoons were lost but some preparatory drawings, that confirm the originality of the work, survived in the Ashmolean Museum, Oxford. There are two studies for the figure of God and one for the angel above Jupiter. Another drawing in the Palais des Beaux-Arts in Lille shows the planet Mars with an angel. This is probably a creative drawing by a pupil suggested by its inferior quality. Luigi da Pace signed and dated the work at the corner of the panel of Venus:
