Today The National Gallery in London opens Metamorphosis: Titian 2012, subtitled "a unique collaboration with The Royal Ballet" (CLICK to learn more). For the first time since the 18th Century the exhibition brings together Titian's paintings Diana and Actaeon, The Death of Actaeon and the recently acquired Diana and Callisto. Sadly the gallery also commissioned some rubbishy British artists to put their own interpretation on these paintings. Mark Wallinger's daft idea is to hire six women called Diana to sit in a bath and be spied on through a peephole (CLICK). It's an insult to Titian.
