 Still working from the 1225 version of the text—the first printed copy of the 1215 charter only emerged in 1610—Coke spoke and wrote about Magna Carta repeatedly.His work was challenged at the time by Lord Ellesmere, and modern historians such as Ralph Turner and Claire Breay have critiqued Coke as "misconstruing" the original charter "anachronistically and uncritically", and taking a "very selective" approach to his analysis.More sympathetically, J. C. Holt noted that the history of the charters had already become "distorted" by the time Coke was carrying out his work.
