摘要

A group of second-year college students have discovered hidden writing on a page from a book from the 1500s. The students found the hidden writing using a special camera system they built. Surprisingly, finding hidden writing on very old documents isn't all that unusual. In fact, there's even a special name for documents like this: a palimpsest. Long ago, writing was done on parchment—thin, dried animal skins specially prepared for writing. But parchment wasn't easy to make and it wasn't cheap. For this reason, it became common to scrape the old writing off of a parchment and then use the parchment again for another piece of writing. That's what creates a palimpsest.
