Leonardo's Last Supper Museum

This guide to Leonardo da Vinci's Last Supper in Milan traces the mural he began around 1495 for Dominican friars, an experimental dry technique that let him rework details but doomed the paint almost immediately. It follows the near-misses that could have destroyed the wall since, from soldiers using the apostles' faces for target practice during the Napoleonic wars to a British bomb that fell nearby in 1943. Best heard standing close to the tilted salt cellar by Judas's elbow.
