The Antikythera Mechanism Episode 6 - Making The Metonic Calendar Train

In this video I make the gearing that drives the Metonic, Callippic and Olympiad pointers. If you're interested in a bit more detail on the ancient Greek approach to calendars, then I recommend this excellent article on the Athenian calendars  - https://www.ancient.eu/article/833/the-athenian-calendar/ 

Cheers,
Chris.
