Famous forgery case

In 1795 a Mr. Ireland brought forward what he claimed to be a new version of "Kynge Leare" which was allegedly written by William Shakespeare himself. In 1796, Edward Malone published a refutation of this document. Mr. Malone had discovered that the questioned manuscript contained pages with twenty different watermarks. He reasoned that an author of Shakespeare's caliber who was also famous and affluent at the time Lear was written, would have gone to a papermaker and secured as much paper of one type as was needed for his work. But someone who wanted to forge an Elizabethan play 200 years later would ferret out such scraps of old paper as he could - from the flyleaves and blank pages of old manuscripts. Indeed, in 1805 the forger wrote his confession and admitted that he had done exactly that. He had paid a bookseller to let him cut out blank pages from the older volumes in his shop.
