The online edition of The Independent has an interesting article that explains how ancient Greek and Roman texts have been made available for reading by the use of infra-red technology.
Excerpt from the article:
For more than a century, it has caused excitement and frustration in equal measure – a collection of Greek and Roman writings so vast it could redraw the map of classical civilisation. If only it was legible.
Now, in a breakthrough described as the classical equivalent of finding the holy grail, Oxford University scientists have employed infra-red technology to open up the hoard, known as the Oxyrhynchus Papyri, and with it the prospect that hundreds of lost Greek comedies, tragedies and epic poems will soon be revealed.
