Maria-Teresa of Savoy, second daughter of Victor-Amadeus III, King of Sardinia (see lots 152 and 163) and his wife Maria Antonieta of Bourbon, was born in 1756 in Turin and died at Klagenfurt in 1805. She was married in 1773 to the Count of Artois, the later King Charles X of France (see lot 265), and, as the mother of the Dukes of Angoulême and Berry (see lot 258), she was the grand-mother of the Comte of Chambord (see lot 256).
Campana (1744-1786), of Piedmontese origin as the Countess of Artois, came to Paris in 1774 and was introduced at Court by the Sardinian Ambassador. Apart from Queen Marie-Antoinette, the Countess of Artois seems to have been his most important patron. Among her best known portraits is the large family group showing her with her three children, formerly in the David-Weill Collection (illustrated in Carlo Jeannerat and Henri Clouzot, Miniatures and Enamels from the D. David-Weill Collection, Paris, 1957, nr 23).
