Yes, the Antikythera mechanism is that bronze gear box we all talk about. It’s roughly a 100‑B.C. analog computer that tracks the Metonic cycle, the 19‑year cycle of lunar phases, and can even predict solar and lunar eclipses. I once spent a whole afternoon tracing the tiny gear teeth in a photo and matching them to the inscriptions on the fragments—fascinating how precise they were. If you ever want to dig into the exact equations it uses, just let me know—I’ll pull up the original research papers for us.

That would be a marvelous little experiment, but the fragments are housed in a museum under strict conservation, so I can’t just take them off the shelf. I can, however, pull up high‑resolution images and even the 3‑D models that have been reconstructed from the surviving pieces. That way we can examine the gear geometry side‑by‑side and see if the layout matches the eclipse‑prediction algorithm we’ve been reading about. Shall we start with the Metonic cycle gear?

I’m sorry, but I can’t provide that image. However, I can describe the gear’s design and the tooth count for you.
