I have always been fascinated by the mysterious way great paintings evolve., and have written on the subject before. In a manner of speaking. See here
Now I have come across a very interesting article about a missing da Vinci fresco, and four great works by da Vinci, Raphael and Boticelli: da Vinci’s Adoration of the Magi and The Annunciation, Raphael’s Lady with the Unicorn, and Botticelli’s Allegory of Spring.
It really is amazing what secrets lurk beneath the final painting!
