Using an ancient Greek mathematical method described by the
philosopher Parmenides, the UCL team not only explained how the cycles
for Venus and Saturn were derived but also managed to recover the
cycles of all the other planets, where the evidence was missing.

PhD candidate and team member David Higgon explained: “After
considerable struggle, we managed to match the evidence in Fragments A
and D to a mechanism for Venus, which exactly models its 462-year
planetary period relation, with the 63-tooth gear playing a crucial
role.”

Professor Freeth added: “The team then created innovative mechanisms
for all of the planets that would calculate the new advanced
astronomical cycles and minimize the number of gears in the whole
system, so that they would fit into the tight spaces available.”
-------------------

Remarkable ancient engineering!  Although as in evolution, it wouldn't
have been created all at once. The brilliant designer would have done
one part, then gradually added more gears to the system to end up with
this wonderful creation. Pretty cool work for 100 BC!
