including the feet of the Christ to make a doorway. In 1726 one
Michelangelo Belotti, an obscure Milanese painter, received L300 for
the worthless labour he bestowed on restoring it. He seems to have
employed some astringent restorative which revived the colours
temporarily, and then left them in deeper eclipse than before. In 1770
the fresco was again restored by Mazza. In 1796 Napoleon's cavalry,
contrary to his express orders, turned the refectory into a stable,
and pelted the heads of the figures with dirt. Subsequently the
refectory was used to store hay, and at one time or another it has
been flooded. In 1820 the fresco was again restored, and in 1854 this
restoration was effaced. In October 1908 Professor Cavenaghi completed
the delicate task of again restoring it, and has, in the opinion of
experts, now preserved it from further injury. In addition, the
devices of Ludovico and his Duchess and a considerable amount of
floral decoration by Leonardo himself have been brought to light.

Leonardo has succeeded in producing the effect of the _coup de
theatre_ at the moment when Jesus said "One of you shall betray
me." Instantly the various apostles realise that there is a traitor
among their number, and show by their different gestures their
different passions, and reveal their different temperaments. On the
left of Christ is St. John who is overcome with grief and is
interrogated by the impetuous Peter, near whom is seated Judas
Iscariot who, while affecting the calm of innocence, is quite unable
to conceal his inner feelings; he instinctively clasps the money-bag
and in so doing upsets the salt-cellar.

It will be remembered that the Prior of the Convent complained to
Ludovico Sforza, Duke of Milan, that Leonardo was taking too long to
paint the fresco and was causing the Convent considerable
