Maybe this was the prototype and the inventor died in the shipwreck..............
When the Roman ship was sunk was probably long after the original scientists had died. This artifact may have been found in a cultural center of Greek heritage as an example of their best science, or for calculating the Greek culture’s main religious or cultural events like the Olympic games or solstices or eclipses. The shipwreck found in 1901 probably represents a final phase of Rome expropriating all that was important of Greek civilization so they could copy and enjoy the brilliance and originality of Greek civilization. Romans were great copiers and conquerors, but their mentality did not begin to have the creativity of imagination of the Greek/Egyption collaboration. Kind of like the Russians of our day where creativity/imagination does not prosper under dictatorships except for artifacts of war.
My hat is off to this small city in Mexico, honoring the best of our inherited civilization. It is so easy to pass off Mexico as the home of drug cartels and poor immigrants.
