After three years of horse-trading - or should that be pig-trading? - the Louvre is finally letting Belgian artist Wim Delvoye show some of his slightly less shocking works. His ‘poo machine’ and live tattooed pigs have been vetoed, but his 36-foot ‘Suppository’ is now sticking straight up into the apex of the Pyramid entrance to this pre-eminent Paris museum. There are also some stuffed, carpeted piglets, contorted crucifixes, and a selection of subversive Gothic-style sculptures on display in the Decorative Arts section this summer. Global meets local, high-brow meets low-brow, in the Wim Delvoye show now on at the Louvre until September. Hugo Vitrani reports.
