Four whaling paintings by the British artist J.M.W. Turner will be united for the first time in an upcoming exhibition in New York City. "Turner's Whaling Pictures" at the Metropolitan Museum of Art opens May 10 and runs through Aug. 7 The paintings were created toward the end of the artist's career. Seascapes and other marine subjects were among Turner's favorite subjects. The whaling paintings were exhibited in pairs at the Royal Academy in London in 1845 and 1846. One of the paintings at the Met comes from its own collection.
