The
Last Supper is one of Leonardo's best-known and worst-preserved pieces.
Doomed from the start by Leonardo's experimental technique, the mural began
to deteriorate even before the artist's death. Within 50 years it was almost
indecipherable, and it was repainted twice during the 18th century. Its
suffering continued through the 19th century, first at the hands of Napoleon's
soldiers, then from the monks who actually cut a door through the
bottom. After miraculously surviving the Allied bombs of World War II,
the beleaguered mural's luck began to change. Restorers discovered that
much of the original work remained, and it is once again a joy to behold.
