Turnbull made this work in plaster, cutting and gouging it before casting it in bronze. It is a head ? the eyes, nose and mouth are just discernable ? re-interpreted for the post-war age. The resemblance to stones, dinosaur eggs and hand-grenades is probably not accidental; the head has the look of something that has been to hell and back and it has no correct way up. Turnbull was one of a group of young British sculptors, including Eduardo Paolozzi, Reg Butler and Lynn Chadwick, who showed in the `New Aspects of British Sculpture? exhibition at the Venice Biennale in 1952. Commentators noted their common interest in geometry, fear and anxiety, which was rife in post-war art of this period. The term `geometry of fear? was coined to describe their work.
