The Liber Veritatis, meaning "Book of Truth" in Latin, is a book of drawings recording his completed paintings made by Claude Lorrain, known in English as "Claude". Claude was a landscape painter in Rome, who began keeping this record in 1635/6, as he began to be highly successful, and maintained it until his death in 1682. The book is now in the British Museum, and was owned by the Dukes of Devonshire from the 1720s until 1957. It was reproduced in print form from 1774 to 1777 by Richard Earlom and had a considerable influence on British landscape art. The title Liber Veritatis was apparently invented for these reproductions, but is now also used for the original.
