This is a revised and greatly expanded edition of a book first published in 1964 by Phaidon Press, and it catalogues in detail over 350 pictures painted since c. 1600. It thus complements The Early Italian Pictures by John Shearman which was published by Cambridge in 1983. The catalogue includes the work of many great painters - Domenichino, Guercino, Guido Reni, Batoni, the two Ricci, Annibale Carracci, Zuccarelli and a famous, unrivalled group of paintings by Canaletto, most of which were commissioned directly from the artist by Joseph Smith and subsequently bought with the rest of his collection by George III. A long introduction traces the history from Charles I onwards of English royal interest in Italian pictures of the seventeenth- and eighteenth-centuries.
