Lorrain was so much appreciated and admired in the XVIII century England, that he was often referred to simply as Claude. His artwork was in such demand that John Boydell, an entrepreneur, artist and publisher, decided to publish the famous sketchbook Liber Veritatis in 1770s. For this purposes, he commissioned the best engraver of that time Richard Earlom to transform Claude's inks and washes into etchings and mezzotints.
