London commuters on their way home might find themselves getting a bit itchy and sweaty today - not just because of the early summer heat. The London Evening Standard has spiced up its arts section with an image liable to get readers hot and bothered. In a sprawling review of artist Alison Watt's display of drapery paintings at the National Gallery, Brian Sewell notes that one of her works "provokes association" with Gustave Courbet's famous nude portrait The Origin of the World. Probably best to stick to Sewell's description of the 1866 canvas, which was banned for a century: "That exquisite examination of a woman's torso approached from between the thighs by a myopic heterosexual". Naturally this is reproduced in its full glory. Sewell also reminds us much later in the article that the 18th century painter Ingres anticipated the Courbet image "with one of his own, surprisingly honest and even more hirsute". Quite.
