His works are numerous, and are dispersed in various public and private
collections of Europe; and when they are offered for sale they command
enormous prices. There are eight of his pictures in the English National
Gallery; one of these, the Woman taken in Adultery, formerly in the
Orleans collection, sold for £5000. In Smith's Catalogue raisonné is a
description of six hundred and forty pictures by him, the public and
private galleries and collections in which they were located at the time
of the publication of the work, together with a copious list of his
drawings and etchings, and much other interesting information. He left
many studies, sketches, and drawings, executed in a charming style,
which are now scarce and valuable.
