John Martin (19 July 1789 – 17 February 1854) was an English Romantic painter, engraver and illustrator. He was celebrated for his typically vast and dramatic paintings of religious subjects and fantastic compositions, populated with minute figures placed in imposing landscapes. Martin's paintings, and the prints made from them, enjoyed great success with the general public—in 1821 Thomas Lawrence referred to him as "the most popular painter of his day"—but were lambasted by John Ruskin and other critics.
