Long-time readers know that I’m not real big on the “spin-off” argument for funding space exploration and technology. Still, when something like this happens, it’s certainly a nice side effect.

Since it was unearthed more than a century ago, the hoard of documents known as the Oxyrhynchus Papyri has fascinated classical scholars. There are 400,000 fragments, many containing text from the great writers of antiquity. But only a small proportion have been read so far. Many were illegible.

Now scientists are using multi-spectral imaging techniques developed from satellite technology to read the papyri at Oxford University’s Sackler Library. The fragments, preserved between sheets of glass, respond to the infra-red spectrum – ink invisible to the naked eye can be seen and photographed.
