LONDON - Preview 'Turner and the Masters,' a major new show that places paintings by JMW Turner alongside the masterpieces that inspired them. Turner repeatedly pitted himself directly against both the old masters and his contemporaries, including Titian, Poussin, Rembrandt, Rubens, Watteau and Veronese – and Constable. The chippiest genius in British art history, Turner was not going to be bested by any other artist, alive or dead.
