Jean-Étienne Liotard (1702-1789 )Profile of the Queen Empress (Maria Theresa of Austria). Circa 1780. black manners. 130 x 165. Roethlisberger-Loche 527. Very nice proof on thin ivory filigree laid paper (bunch and letters). Normal ripples, due to the pressure of the print. Margins. At the opening of his Traité des règles et des principes de la peinture (1781), Liotard writes: "I have had engraved, and partly engraved myself, seven prints of different sizes. I have scrupulously observed in their composition the principles set out in this work. ...] "He places the portrait of Empress Maria Theresa in his list out of deference under No. V, before that of his own daughter (No. IV), whose godmother is the previous one whose first name she bears. About this portrait, he writes: "I had the honour of drawing her august person in 1744. I engraved it myself, and surrounded his medallion with a garland of roses and laurel. She did well to justify this emblem. »
