Liber Studiorum

Series of etched and mezzotinted plates by the English painter J M W Turner designed to illustrate various styles of landscape, published 1807–19. Of a projected 100 plates, 71 were completed.

Turner took the idea of such a collection of monochrome studies from Claude Lorrain's Liber Veritatis. He etched all the plates in outline but left it to professional engravers to complete them in mezzotint.
