The biblical David was a popular subject among
Renaissance artists and had been treated by sculptors such as
Donatello (1440s),
Verrocchio (1473-1475) and
Michelangelo (1501-1504). Bernini's
David, though engaging with these works, differed from them in some significant ways. For one thing, the sculpture is no longer self-contained, but interacts with the space around it. Not since the sculptures of the
Hellenistic period, such as the
Winged Victory of Samothrace, had sculptures been involved in their surroundings like those of Bernini. A likely source for Bernini's figure was the Hellenistic
Borghese Gladiator. The motion of the gladiator preparing to attack is similar to how
David is swinging his sling. Another difference lies in the moment that Bernini has chosen to depict. Michelangelo's
David differs from those of Donatello and Verrocchio in that it shows David preparing for the battle, rather than victorious afterwards. Bernini, on the other hand, chose to portray David in the act of throwing the stone. This represented a novelty; throwing figures were extremely rare in post-Antiquity sculptures. The motion motif did exist in painting, however, and one example was
Annibale Carracci's
fresco of the
Cyclops Polyphemus throwing a stone. Bernini may also have been familiar with the writings of
Leonardo da Vinci on the subject. Da Vinci, in his
Treatise on Painting, deals with exactly the question of how to portray a throwing figure. It is possible that Bernini applies this theory to his
David: Another potential candidate as inspiration for Bernini's
David is the celebrated 5th century BC
Discobolus by
Myron. However, the problem with this theory is that the
Discobolus was in the early 17th century only known from literary sources; the torsos of copies that had survived were not correctly identified until 1781. Both
Quintilian and
Lucian wrote of the statue, but the descriptions were of a figure stretching or flexing, rather than being in the act of throwing. ==Style and composition==
