- Description
- My father had a collection of personal items that used to belong to famous astronomers. He used them in his work, and if my father left a hint about where he was going, he probably put it in code. The collection will help us decipher it. One of the items is the gnomon of Meton of Athens. Please find it.
- Completed
- The gnomon you found is an ancient sundial. Meton used it to create the lunar and solar Greek calendar.
