Antonio Maria Zanetti
Count Anton[io] Maria Zanetti (1679–1767) was a Venetian artist, engraver, art critic, art dealer and connoisseur. He formed a collection of engraved gems, of which he published a lavish catalogue.
Zanetti spent his early manhood making wise investments in marine insurance, accumulating sufficient capital to support his true vocation, as a writer and artist, and as an art dealer, doing much of his business with the English aristocrats who passed through Venice on the Grand Tour. He acted as paintings agent for Philippe d'Orléans in forming the Orléans collection, Paris, and Joseph Wenzel I, Prince of Liechtenstein, in expanding the Liechtenstein collection, Vienna. Pierre Crozat, being in Venice in 1715, persuaded Zanetti and his protégé Rosalba Carriera to go to Paris. Zanetti also visited London, where he purchased Jan Petersen Zoomer's three large volumes containing 428 Rembrandt etchings in outstanding impressions of the various states.
He formed a collection of engraved gems, both Greco-Roman and modern, of which he published a lavish catalogue, in the form of A.F. Gori's Le gemme antiche di Anton Maria Zanetti (1750), illustrated with eighty plates of engravings from his own drawings. The drawings for the engravings, and many of his intaglios and cameos, are conserved in the Museo Correr, Venice. His prize piece, a black cameo of Hadrian's favourite, Antinous, which he had pursued for years before acquiring it, was bought by George Spencer, 4th Duke of Marlborough and gained the sobriquet of the "Marlborough gem".
Anton[io] Maria the younger (1706–1778), was the son of a cousin, who became his protegé and developed into a distinguished critic; he collaborated with his elder cousin, providing most of the drawings for a sumptuously illustrated account of the classical sculpture conserved in Venetian public collections, Delle antiche statue greche e romane che nell'anti sala della Libreria di San Marco e in altri luoghi pubblici venezi son trovato, I, Venice, 1740, II, Venice, 1743. Their collaborator for the text was Gori. Zanetti the younger was also a close friend of the painter and collector of engravings, Domenico Bernardo Zillotti (or Zilotti).

Il auroit, disoit-il, vendu sa maison pour l’acheter, s’il eût été parfait." (Pierre Clément, 1756, quoted in Antinous website)
