I think this is fantastic and wonderful news. Can there be original copies of manuscripts by Plato or Achemedies(sp?).. I hope they are able to repair and translate as many as possible. How anyone could find something neagtive to say about such a wonderful gift/find to humanity is beyond me..
Back in the late 19th and early 20th century, a lot of Greek texts were found on papyri in Egypt, including some works that had been lost, and there have been some additional discoveries since then, like the Nag Hammadi gnostic library in the 1940s...so there is always a chance of more being found.
