A New Caravaggio?

A New Caravaggio? wonders L'Osservatore Romano, the mouthpiece of the Vatican. And just in time to mark the 400th anniversary of his death! Unfortunately this is the photo it published of The Martyrdom of St Lawrence supposedly by Caravaggio. The painting's one notable feature is that it breaks with tradition. All the other works I've seen which show the roasting of St Lawrence over a fire have him on his back, looking pious and with a free hand pointing to Heaven, as you do when you're bucking for sainthood. The light source seems a bit iffy for Caravaggio.
