Smart people at Oxford have invented a way to recover the text of papyri from an Egyptian dump. The papyri were discovered about 100 years ago, but no one has been able to read them until now.
Apparently, they've already recovered some Sophocles that was previously completely unknown. I'm pulling for a copy of Plato's lecture on the good to be among the papyri. If that's not available, some dialogues of Aristotle will do.
