It was thought that no bronzes by Michelangelo had survived - now experts believe they have found not one, but two - with a tiny detail in a 500-year-old drawing providing vital evidence.

They are naked, beautiful, muscular and ride triumphantly on two ferocious panthers. And now the secret of who created these magnificent metre-high bronze male nudes could well be solved. A team of international experts led by the University of Cambridge and Fitzwilliam Museum has gathered compelling evidence that argues that these masterpieces, which have spent over a century in relative obscurity, are early works by Michelangelo, made just after he completed the marble David and as he was about to embark on the Sistine Chapel ceiling.

If the attribution is correct, they are the only surviving Michelangelo bronzes in the world.
