    Not a lot new under the sun when it comes to the Greeks.

    As a diver of 40+ years experience, I know the chance of finding this was pretty astronomical. (sorry about the pun.) Surely there should be other examples or documents relating to this?

    If unique, even more amazing. A bit like life on earth. ( where are the other examples out there? ET where are you?)

    One of the attractions of Cel Nav for me is the shear infinity of the universe and our ability to measure a few selected angles from bodies hundreds/ thousands of light years away,  and know roughly where we are right now. The few photons hitting our retinas after a journey lasting maybe  thousands of years , tells us, with a bit of simple maths,  where we are now! Miraculous or what?

    As I work on x-ray tomography this was a really interesting example of
    its use in archaeology. I have spoken to some of the people involved
    who were able to read inscriptions on the inside face of gear wheels
    which helped understand its purpose. It makes you wonder if they had
    other devices of similar complexity in ancient Greece.
