In the terrestrial Paradise, hinted only by the splintered rocks on the sides, is the forbidden fruit tree, on which the tempting Serpent is coiled, with a delicate hairy head that recalls the analogous subject of Masolino's original Sin in the Brancacci Chapel. Adam and Eve are naked and if the first has a strong musculature and a realism attentive to detail, the second has a smooth and well-rounded complexion. their gestures are very eloquent: on the one hand Eve accepts the apple with condescension, on the other Adam condescendingly attends, with one arm outstretched, typical of Jacopo della Quercia's style, which seems to compress his figures between two invisible planes.

Jacopo di Pietro d'Agnolo di Guarnieri known as Jacopo della Quercia (Quercegrossa, about 1374 - Siena, 20 October 1438) was an Italian sculptor. He attempted a synthesis between the gothic sculpture of Giovanni Pisano and the Burgundian one, especially of Claus Sluter on the one hand, with classicism on the other, assimilated through the new discoveries of the Florentine Renaissance: his greatest interest turned to the figures, rendered monumental and traversed by an overwhelming vitality. His work found no immediate followers. He was stylistically a block, which was later understood only by Michelangelo.
