Evidence: The relatively few copies of Archimedes ' written work that survived through the Middle Ages were an influential source of ideas for scientists during the Renaissance , while the discovery in 1906 of previously unknown works by Archimedes in the Archimedes Palimpsest has provided new insights into how he obtained mathematical results.
The Archimedes Palimpsest is a parchment codex palimpsest , which originally was a 10th-century Byzantine Greek copy of an otherwise unknown work of Archimedes of Syracuse and other authors.
