which remains a principal source for the period. From his arrival in London in 1720, the Flemish sculptor John Michael Rysbrack was the leader in his field until the arrival in 1730 of Louis-François Roubiliac who had a Rococo style which was highly effective in busts and small figures, though by the following decade he was also commissioned for larger works. He also produced models for the Chelsea porcelain factory founded in 1743, a private enterprise which sought to compete with Continental factories mostly established by rulers. Roubiliac's style formed that of the leading native sculptor Sir Henry Cheere, and his brother John who specialized in statues for gardens. The strong London silversmithing trade was dominated by the descendants of Huguenot refugees like Paul de Lamerie, Paul Crespin, Nicholas Sprimont, and the Courtauld family, as well as Georges Wickes. Orders were received from as far away as the courts of Russia and Portugal, though English styles were still led by Paris. The manufacture of silk at Spitalfields in London was also a traditional Huguenot business, but from the late 1720s silk design was dominated by the surprising figure of Anna Maria Garthwaite, a parson's daughter from Lincolnshire who emerged at the age of 40 as a designer of largely floral patterns in Rococo styles. Unlike in France and Germany, the English adoption of the Rococo style was patchy rather than whole-hearted, and there was resistance to it on nationalist grounds, led by Richard Boyle, 3rd Earl of Burlington and William Kent, who promoted styles in interior design and furniture to match the Palladianism of the architecture they produced together, also beginning the influential British tradition of the landscape garden, according to Nikolaus Pevsner "the most influential of all English innovations in art". The French-born engraver Hubert-François Gravelot, in London from 1732 to 1745, was a key figure in importing Rococo taste in book illustrations and ornament prints for craftsmen to follow. Late 18th century In the modern popular mind, English art from about 1750–1790 — today referred to as the "classical age" of English painting — was dominated by Sir Joshua Reynolds (1723–1792), George Stubbs (1724–1806), Thomas Gainsborough (1727–1788) and Joseph Wright of Derby (1734–1797). At the time Reynolds was considered the dominant figure, Gainsborough was very highly reputed, but Stubbs was seen as a mere painter of animals and viewed as far a less significant figure than many other
