And it is that which would date the mechanism easiest as that is measurably changing over time. If the mechanism is reasonably accurate and actually rather old it will throw up an error. Archaeology will call it an error, of course, as it will not agree with a later observation at a date they will have set. Unlike science the preordained theories are more reliable evidence than what is actually found, though science is falling into the same trap now with Big Bangs etc. See Sphinx dated by a cartouche of a Pharaoh found between its paws. That means Stonehenge is not pre war as I found a Smartie tube next to one of the stones and Smarties did not exist pre war. Case solved! What utter tosh.
If it is in fact very old it might even have evidence of the effect of a heavily glaciated Earth pre deluge theorists. That would be very interesting, not least if its orientation is 'wrong'. There is good evidence that a pre historic mapping system might have been used based on 60 units. Actually this makes a lot of sense and I will leave you to wonder why the full zodiac, not the standard fortune telling one, has 60 positions each with a symbol, many vary well known but of forgotten origin. There are 360 degrees in a circle, 60 times 6. This older system is still there behind our modern one.
Meanwhile we can all ignore the idea that this ship might have been carrying an old antique as part of its cargo on the basis that antiques were not invented. A clinching argument, there, then. I wonder if there is a reason why the easiest bit to date the mechanism is missing.......
