The "Portrait of Francesco Bartolozzi" was created by Anton Raphael Mengs (1728–1779), a German Neoclassical artist. The authorship of the work is confirmed by the attribution preserved since the times of Lukasz Dabski, whose collection the work originally belonged to, and the specialists of the State Hermitage who authenticated the canvas in the 1960s. The virtuosity and freedom of painting style, free arrangement of the figure in space, the informality of composition while maintaining clear architectonics, the rational combination of dynamics and balance, representativeness and reproduction of the momentary psychological state and individual characteristics indicate that the painting from the collection of Borys Voznytskyi Lviv National Art Gallery was created by Anton Raphael Mengs. The deep, warm, and rich colour of the canvas associates it with the other attributed works by the artist. The chamber and sublime interpretation of the image is prompted by the portrayed character of Francesco Bartolozzi (1727–1815), the Italian master of watercolour miniatures and reproduction engravings, who, after studying in the engraving workshops of Florence, Rome, and Venice, in 1764 moved to London, where he became a virtuoso in the so-called dotted technique. The brush in Francesco Bartolozzi's hand emphasises his belonging to the art world.
