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.
