Illusionistic window

Vasari points out that Salviati, in addition to his work on the narrative frescoes, also executed some of the decorative details - the window framing between his two scenes, but also the illusionistic window to the right of the Birth of St John the Baptist scene. These window framings, with their nude youths atop festoons of fruit, are primarily decorative displays of artistic virtuosity; at the same time they contain elements - for example the tondo with the chiaroscuro depiction of Time revealing Truth - that can likewise easily be seen as referring to the theological content of the frescoes as well as to the work of the confraternity.
