Under the statue is a stone relief in which Donatello first used a method known as
rilievo schiacciato, a form involving very shallow cuts into the surface. The scene depicts St. George slaying the dragon in the middle, a cave on the left, a
colonnade on the right, and a background consisting of swaying trees and rolling hills. The closest objects are carved in relatively high relief, whereas the cave, the colonnade and the background trees and hills are carved in low relief. With the use of this relief method, weathering over time has created some difficulty in making out subtle carvings. The relief has been celebrated by scholars for the effect of
prontezza (alertness or preparedness), which influenced later artists. The relief is also significant for taking the form of a
predella, a feature uncommonly found in sculpture. ==References==
