I had no clue what I was going to do with this combo..
I did know that I was going to pick Demeter though, because she was my first thought.
I went with a clock that also shows the seasons, since she is the reason there are multiple times of year in greek mythology.
It also loosely based on the Antikythera mechanisma, an ancient Greek analogue computer and mechanical solar system that was used to predict astronomical positions and eclipses for calendar and astrological purposes many years in advance. It could also be used to track the four-year cycle of athletic games which were much like the Olympics of today.
