"The Last Supper" is painted on the dilapidated wall of what was a little chapel attached to the main church in ancient times, I suppose.

It is battered and scarred in every direction, and stained and discolored by time, and Napoleon's horses kicked the legs off most the disciples when they (the horses, not the disciples,) were stabled there more than half a century ago.
I recognized the old picture in a moment--the Saviour with bowed head seated at the centre of a long, rough table with scattering fruits and dishes upon it, and six disciples on either side in their long robes, talking to each other--the picture from which all engravings and all copies have been made for three centuries.

Perhaps no living man has ever known an attempt to paint the Lord's Supper differently.

The world seems to have become settled in the belief, long ago, that it is not possible for human genius to outdo this creation of da Vinci's.

I suppose painters will go on copying it as long as any of the original is left visible to the eye.
