George Stubbs was marvellous English animal painter and anatomical draftsman, famous for his paintings of horses. Stubbs also painted a wide range of other animals, including the lion, tiger, giraffe, monkey, and rhinoceros, which he was able to observe in private menageries. According to the Ozias Humphrey, Stubbs was so convinced of the importance of observation that he visited Italy in 1754 only to reinforce his belief that nature is superior to art. Among Stubbs's best-known pictures are several depicting a horse being frightened or attacked by a lion (Horse Frightened by a Lion, 1770). His historical paintings are among the least successful of his works; much more convincing are his scenes of familiar country activities done in the 1770s. Unfortunately, he tended to execute his paintings in thin oil paint, and relatively few survive in undamaged condition. Stubbs's last years were spent on a final work of anatomical analysis, for which he completed 100 drawings and 18 engravings.
