Longitude?

After many years of trying in 1773 John Harrison was finally credited with the news that his invention – a very accurate watch – was usable by seamen to calculate longitude from the ‘mean’ line of Greenwich.
It follows then that until that time sea-going folk couldn’t calculate longitude. Yet for years the oceans had been sailed by folk the world over. How had they managed to figure-out where they were? And, by inference, how had the old maps of the world been initially drawn?
This thing looks useless here, but 2000 years ago it was well used – it had on occasion been repaired – so some folk did know what it did and how to use it perfectly well. Could this apparatus have been a longitude calculator?
It has been long conjectured that a race, group or even gang of people have existed on Earth that have possessed some form of ancient knowledge. Navigating Earth might have been part of that knowledge and to do it they had sophisticated machinery that they had made.
The mechanism above was found amid an old ship-wreck and one can but wonder if one of the ‘knowledgeable ones’ was on-board the ship, with his mechanism, at the time that the ship sank…
…or were, perhaps, the sailors merely transporting the mechanism, with no idea of its usage…
It took John Harrison several attempts to knock-up an accurate sea-going clock – so somewhere, perhaps, there might be more ‘mechanisms’ – which are simply machines with gears.
Like lathes. Or cranes. Or motors.
