John Constable's (1776–1837) seminal six-foot landscapes—among the best-known and beloved images in British art—are reunited with their groundbreaking full-size sketches for the first time since the artist's death in 'Constable's Great Landscapes: The Six-Foot Paintings,' at the National Gallery of Art, East Building, October 1 through December 31, 2006. Fifty-five works include oils and drawings that are related to the large landscapes, an early pencil portrait, and a series in varied media brought together for the first time, illustrating areas along the Stour River in Suffolk known to many as 'Constable Country.' The exhibition and its companion catalogue examine why Constable produced the six-foot sketches.
