Several pentimenti are hidden beneath the paint layers on this page; in some cases, they can be perceived with the naked eye, through the light blue azurite used in the sky. They are more easily seen in the near-infrared image and become even clearer in the images recorded using infrared reflectography (hotspots 1 and 2).
