J.M.W. Turner 1775-1851 was perhaps the most prolific and innovative of all British artists. His outstanding watercolors in the Scottish National Gallery are one of the most popular features of its collection. Bequeathed to the Gallery in 1899 by the distinguished collector Henry Vaughan, they have been exhibited, as he requested, every January for over 100 years. Renowned for their excellent state of preservation, they provide a remarkable overview of many of the most important aspects of Turner's career.

This richly illustrated book provides a commentary on the watercolors, addressing questions of technique and function, as well as considering some of the numerous contacts Turner had with other artists, collectors and dealers. The introduction concentrates on Henry Vaughan, one of the greatest enthusiasts for British art in the late nineteenth century, whose diverse collections have not previously been fully appreciated.
