Contemporary artists are often accused of infantilism - but few of them take the charge on board as literally as this. Marc Quinn, the sculptor who achieved national prominence when his portrayal of his pregnant disabled artist friend Alison Lapper was installed on Trafalgar Square's fourth plinth, is once more turning his attention to the vulnerability of the human form.

The results can be seen in the splendid grounds of Chatsworth, the Peak District home of the Duke and Duchess of Devonshire, where a giant effigy of a naked infant, cast in bronze and painted in brilliant white, is currently being installed.
