I was swept along in a big group past Leonardo’s “Salvator Mundi” – Saviour of the World – in the National Gallery exhibition. Then everyone for a short time moved on and I was left staring straight into the eyes of this extraordinary picture staring back.

Thus we are swept along in a great tide of humanity, barely pausing, remaining for an instant on His beauty and then moving on. But it is entirely impossible to pause, to stand still, and be alone with Him (certainly not in the National Gallery).
