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. A notable feature of Donatello's relief work is his implementation of the
predella, a feature uncommonly found in sculpture. The predella has been celebrated by scholars for its use of prontezza, alertness or preparedness, which inspired future use during the
Renaissance Period. Scholars believe that the military equipment found in the relief is copied from that of the physical statue, meaning that the relief was most likely created one to two years after. Found in this relief are a woman observing 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. ==References==
