Way back in the 1990s, art already seemed poised to enter the realm of the dead. After Damien Hirst won the 1995 Turner prize for his vitrines containing the bisected bodies of a mother cow and her calf , where could he go next? Was he about to put a human body on view? In the event, he never stepped over that line. He just sank more animals into tanks of formaldehyde in ever sillier ways . Instead it was Gunther von Hagens, inventor of “plastination”, who got people queuing up to see dead people posed as sculptures , their anatomies eerily revealed.
