In April 2007, it was announced that a new text had been found in the palimpsest, a commentary on Aristotle's Categories running to some 9 000 words. Most of this text was recovered in early 2009 by applying principal component analysis to the three color bands (red, green, and blue) of fluorescent light generated by ultraviolet illumination. Dr. Will Noel said in an interview: You start thinking striking one palimpsest is gold, and striking two is utterly astonishing. But then something even more extraordinary happened.
