Framed in the wall to your east is a remarkable shallow painting of the
palace residents.  They are depicted walking to the palace well, its source
is indicated by a seminude female personification of a spring.  To your west
you can see an unobstructed view of the retrochoir, used by those seeking
absolution from the royal papal figures.  Engaged columns form the
articulated opening of the arch above, underneath runs the western hallway
which extends north and south.
