Between these two landmark works comes the efforts of a painter, Andrea del Costagno, who contributed his vision of the David tradition in a painted shield done about 1450-55. Although he was undoubtedly familiar with the Donatello sculpture, his painting however bears little resemblence to it. Thi's David is an athletic young man, dressed in a short, white shirt and flowing red tunic, wielding his sling and stone, arm upraised, standing over the severed head of Goliath, defending the faith, taking on all comers.
Costagno's inspiration seems to have been sculptural. However it bears no debt to the the Early Renaissance, but to Roman sculpture instead, and strangely, it seems based upon an ancient statue in marble of a FLEEING warrior. Yet there is no hint of fear nor flight in this work. Costagno's strongly defiant David may, in fact, have been the inspiration not just for Verrocchio, but for Michelangelo as well. Yet it is more than that. It is a figure in a fighting pose, not unlike that of Gianlorenzo Bernini's Baroque marble of David done almost 175 years later.
