13th-Century Monk's Manuscript Preserves Archimedes' Mathematical Works
In 1229, a Greek Orthodox monk named Johannes Myronas in Jerusalem created a prayer book by erasing and overwriting existing parchment. Unbeknownst to him, the original pages contained the only known copies of certain works by the ancient mathematician Archimedes. This act of overwriting, known as creating a palimpsest, inadvertently preserved these significant mathematical texts. The Archimedes Palimpsest, as it is now known, was later discovered and studied using modern technology, revealing Archimedes' advanced mathematical concepts, including early forms of calculus and combinatorics. The manuscript's journey culminated in its sale at a 1998 auction for $2 million, leading to extensive conservation efforts.
