'Though searching damps and many an envious flaw
Have marred this Work.'
This picture of the Last Supper has not only been grievously
injured by time, but the greatest part of it, if not the whole, is
said to have been retouched, or painted over again. These niceties
may be left to connoisseurs.--I speak of it as I felt. The copy
exhibited in London some years ago, and the engraving by Merghen,
are both admirable; but in the original is a power which neither
of those works has attained, or even approached.
