Which artist was famous for horse paintings?

George Stubbs ARA (25 August 1724 – 10 July 1806) was an English painter, best known for his paintings of horses. Self-trained, Stubbs learnt his skills independently from other great artists of the 18th century such as Reynolds or Gainsborough. Stubbs' output includes history paintings, but his greatest skill was in painting animals, perhaps influenced by his love and study of anatomy. His series of paintings on the theme of a lion attacking a horse are early and significant examples of the Romantic movement that emerged in the late 18th century. His painting, Whistlejacket hangs in the National Gallery, London.

In 1754 Stubbs visited Italy. Forty years later he told Ozias Humphry that his motive for going to Italy was, "to convince himself that nature was and is always superior to art whether Greek or Roman, and having renewed this conviction he immediately resolved upon returning home". In 1756 he rented a farmhouse in the village of Horkstow, Lincolnshire, and spent 18 months dissecting horses, assisted by his common-law wife, Mary Spencer. He moved to London in about 1759 and in 1766 published The anatomy of the Horse. The original drawings are now in the collection of the Royal Academy.
