Well who should be so lucky? I’ve just had another look at the Sistine Chapel. And my reaction was as when first I beheld the famous frescoes in 1950: it’s not natural for so much spaghetti to be in the sky. What if there should be a dreadful earth tremor, as at Assisi a couple of years ago when the ceiling of St Francis’ church collapsed in a great dump of dust? Might the heavenly pasta here plunge thundering down and squash one ’neath its glutinous glop? I huddle near a handy exit. Why do Michelangelo’s compositions wriggle so?
