Sculpture
Visitors viewing A Subtlety, or the Marvelous Sugar Baby, a sugar-coated polystyrene sculpture by Kara Walker, 2014, part of a temporary installation at the former Domino Sugar Refinery in Brooklyn, New York.
Donatello brilliantly exploited the unique properties of white marble to enhance the visual impact of his work. Because pure white marble possesses a translucent quality, it appears to glow and responds to light in a delicate, subtle manner.1
Donatello utilized these characteristics in several ways:
- Atmospheric Effects: In his schiacciato (flattened out) relief technique, such as in St. George Killing the Dragon, he used extremely shallow carving to create a striking sense of atmospheric space, effectively "painting" with his chisel rather than modeling shapes in the traditional way.2
- Light Manipulation: His highly developed marble reliefs, such as The Ascension, with Christ Giving the Keys to St. Peter, were carved with such delicacy that their full beauty is revealed only when viewed under a strongly raking light.2
- Expressive Force: In his monumental statues, such as the Zuccone and Jeremiah, he used the stone to capture highly individual features inspired by ancient Roman portrait busts, imbuing the figures with singular expressive force.2
By mastering these qualities, Donatello transformed the material to achieve effects that transcended the physical limitations of stone.1
