A lifelong collector of old master paintings, Liotard owned from an unknown source what he treasured as a fine Venus by Titian, first recorded in 1756, sold in Paris in 1788, hence lost. No exact model is known. A late 18^th-century engraving by Romanet is almost certainly after this work. Vanderlyn's Ariadne Asleep, painted in Paris c. 1810, offers a comparable composition. Liotard copied the Titian twice in pastel , probably in the 1760s, and in 1781 made his largest mezzotint after it for his treatise, where he praised it in the chapter on Grace. Another among his rare classical themes is the Callipygous Venus of 1774, which he copied in pastel in London after a plaster cast and likewise turned into a mezzotint.
