Digital imaging methods have been developed and adapted to analyze the so-called "Archimedes Palimpsest", which is a 10th century overwritten manuscript including the oldest known copies of seven of the treatises of Archimedes. Multispectral digital images of five of the leaves of the palimpsest have been collected, processed, and analyzed using principal component analysis and orthogonal subspace projection techniques. These methods have been applied to "strip off the later overwriting to reveal the original text.
