 The panel is set in a shed enclosed by two pillars and an archway, rendered in sculpture-like grisaille. Each pillar is supported by a relief hunched figure (atlante) at the base, holding the weight on its shoulders. On each pillar stand statues of Adam and Eve – Adam on the left and Eve to the right. A marble threshold connects the two structures. On the top corners of the arch are two spandrels; the archivolts contain six biblical scenes in relief from the Book of Genesis, depicting the Fall of Man. Two are of Adam and Eve; their expulsion from paradise and Adam tilling the soil. The others are of Cain and Abel: their sacrifice to God; Cain slaying Abel; God appearing to Abel; Cain expelled to the Land of Nod.
