oldest found astrolabe

[Schwob]

Not sure which sub forum to put this, there seems to be none on UW archeology.

Also, this is more detail on an older find from 2014... Presumably there are more reports on such finds etc. Where does one find these reports on (more archeological than treasure hunting) shipwreck and sunken city expeditions and such?

Excellent post. Only 250 years later, precision clocks were designed to determine longitude.
