It's always interested me that although the instructions are written in Greek, there are absolutely no other similar examples of this type of Mechanism in the Greek engineering record for over 1000 years.
It seems to me that because the mechanism used mathematics that are traditionally thought as "Greek"; historians assume it was made by the Greecians.
When we actually look at the origins of Maths as we know it today, it seems many Greek attributed theories were in fact from the Indian vedic period (trigonometry) and Babylonian/Persian/Arab scholars who later developed this work.
The Greeks were the first European society to learn the old knoweldge and after a few subsequnet tweaks by Modern Scholars in history text books; suddenly the Greeks are the fathers of all knowledge.
I call OOPART,,,in fact I think its the only proven OOPART ever discovered and is significant enough to ask the question of how far technology cvan develop locally on Earth in advance of other cultures.
If we look at today and compare the US ( The I-Phone in Space country) with Papua New Guinea I wonder how long it would take Papua New Guinea to put a man on the moon if Europe, Amercia and Asia were suddenly submerged taking all that info with them???

Cicero's De re publica, a 1st century BC philosophical dialogue, mentions two machines that some modern authors consider as some kind of planetarium or orrery, predicting the movements of the Sun, the Moon, and the five planets known at that time. They were both built by Archimedes and brought to Rome by the Roman general Marcus Claudius Marcellus after the death of Archimedes at the siege of Syracuse in 212 BC. Marcellus had great respect for Archimedes and one of these machines was the only item he kept from the siege (the second was offered to the temple of Virtus). The device was kept as a family heirloom, and Cicero has Philus (one of the participants in a conversation that Cicero imagined had taken place in a villa belonging to Scipio Aemilianus in the year 129 BC) saying that Gaius Sulpicius Gallus (consul with Marcellus' nephew in 166 BC, and credited by Pliny the Elder as the first Roman to have written a book explaining solar and lunar eclipses) gave both a "learned explanation" and a working demonstration of the device.
I'm wondering what the bronze statue had in its right hand at one time. The positioning of his hand looks almost like he could have been holding the infamous cone we often see in Sumerian reliefs.
New interpretations of the Antikythera Mechanism reveal that it could be used to predict eclipses,

Thanks for the info, that's more or less how I see the Antikythera mechanism, it's useful like an orrey or the moon dial on a grandfather clock - great at showing you the next convergence of moon and planets and sun for eclipses and the like. I even had a simple "paper computer" from one of those Astronomy magazines back when I was a kid that would show what planets or constellations would be visible once you turned the paper dials to the correct dates. The Antikythera mechanism is a work of genius, but as far as telling the time of day - doesn't do it.
It's simply not a machine for navigation at sea. You need an accurate timepiece (that functions on a rolling ship), the ability to determine high noon, and a concept of longitude and latitudes, and none of that came into a workable system until the British Royal Navy made it work. The Antikythera mechanism is a calendar, not a clock.
Thus, if a known star is in a given position on the celestial sphere (measured by azimuth and right ascension), a table could be drawn up at a given location for each night, showing how distant the Moon appears to be from that star.
For example: If a ship sailed west out of a port, and its new longitude were now 15 degrees west (one hour) of that port, and those on the ship could see the Moon and the reference star, the Moon would appear to be 0.5 degree east of where the table would show it to be for the port of departure. There is nothing here that navigator Maui in 232 B.C. could not have known. The only question would be whether his instruments could measure an angular difference on the order of 0.5 degree.
Our Observations Our observational experiment showed that a simplified torquetum could do it. In the time that Altair had moved 41.8 degrees west along the equatorial plane, the Moon had moved only 40.25 degrees, a difference of 1.55 degrees. Because the Moon should retrograde about 0.5 degree/hour, the calculated regression would equal 1.39 degrees. This error of less than 1/6th (or 0.166) of a degree is well within our instrument limitations, which can be read only to 0.25 of a degree.
