The Archimedes Palimpsest

This email has nothing to do with category theory directly but I am sure it will interest list members. (The word `categories' is on the web site below!) Yesterday I went to a talk at the Bangor Classical Society on the orator Hypereides by Professor Stephen Todd of Manchester. What was new on this orator (a barrister, in our terms) came from the discovery of the Archimedes Palimpsest. All you need to do is look on http://www.archimedespalimpsest.org/ Fascinating in terms of discovery and the technology to reveal the scraped off and overwritten text! Ronnie
