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.
Vision of a Knight (Raphael)
The Vision of a Knight, also called The Dream of Scipio or Allegory, is a small egg tempera painting on poplar by the Italian Renaissance artist Raphael, finished in 1504–1505. It is in the National Gallery in London. It probably formed a pair with the Three Graces panel, also 17 cm square, now in the Château de Chantilly museum.
