Letter: Leonardo

Sir: Why all the fuss about Leonardo's Last Supper (report, 26 May)? It is known that technical problems started when it was barely finished. Flaking paint got lost over the intervening centuries and repair has meant compromise or approximation for a long time. Why no fuss about all the other old masterpieces which now look like 20th- or 21st-century art? It seems that every period restores to the taste of its time. Nobody complained when, years ago, objections could have helped pictures by great masters to remain masterpieces. Do we only care for lost causes?
