Browsing some art books today I was rather struck by this sculpture of David by Giacomo Manzu, c.1939, and by the more usually helpful write up in the book:
"The biblical figure of David has been a continuing source of inspiration in the work of Manzu. Several versions exist of this subject whose main characteristic is a crouching figure ready to let fly with a sling. From the first realization of 1935 to the later ones of 1938-39, there is a clear break in the choice of subject; David is no longer a virile nude with head and chest erect, as in the first version, but a thin child whose curved back echoes the rounded form of the stone on which he is crouching. In choosing a young boy as David, Manzu expressed his poetic vision of a child struggling against violence."
