Hey Mike
Just to add a little timeline of things that were happening around that time frame around 2300 yrs ago..292 BC
605 BC: Nebuchadnezzar II leads the Babylonians to conquer Carchemish and defeat the Egyptian army
525 BC: Cambyses of Persia conquers Egypt at the battle of Pelusium
404 BC: Amyrtaios of Sais expels the Persians (28th, 29th and 30th dynasties)
343 BC: the Persians conquer Egypt again (31st dynasty)
332 BC: Alexander the Great conquers Egypt
331 BC: Alexander founds Alexandria in Egypt
323 BC: Alexander dies at Babylon and Ptolemy inherits Egypt
312 BC: Ptolemy's general in Syria, Seleucus Nicator, establishes a kingdom ranging from Syria in the west to India in the east and founds the Seleucid dynasty
307 BC: Ptolemy I creates the library of Alexandria (Museum)
300 BC: Ptolemy I builds the Pharos of Alexandria
283 BC: Ptolemy dies
198 BC: the Seleucids under Antiochus III conquer Palestine from the Ptolemaics
307 BC: Ptolemy I creates the library of Alexandria
which was the worlds center of knowledge , the library housed
what could be told as the knowledge of the world in that day.
There were many genius's around at that time in alexandria
who were particularly interested in mechanics , levers , gears , buoyancy , etc...
I think the first mechanical clock was invented there
but I cant remember by whom.
I kind of suspect that this might be the work of an
alexandrian , or someone studying in alexandria at the time.
or perhaps the result of someones studies there such as
archimedes although he died before the mechanism was made , he may have been a direct influence on its inventor.
archimedes returned to syracuse after his studies in alexandria.
this calculator has been an interest of mine for a long long time.
thanks for the update.
