Manuscripts that have been written upon more than once are known as palimpsests
(from the Greek palimpsestos, "scraped again"). The ink
of the original text has been scraped away to make room for the new text,
yet a dim after-image of the original remains. A careful look at the margins
will reveal a cursive script, apparently in a vernacular language rather
than in Latin, although the words are too faint to identify the text accurately.
Ultraviolet light can sometimes help to bring out an underlying text.
Purchased in 1885 for A. D. White.
