George Stubbs ARA was an English painter, best known for his paintings of horses. Self-trained, Stubbs learnt his skills independently from other great artists of the eighteenth 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 painting 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.
