1.25" x 1.25" - Saturn was the most distant planet known to the ancients, and prehaps the most beautiful sight in the Solar System. The rings of Saturn are not unique but are spectacular and much more elaborate than those of any other planet. The term planet originally meant "wanderer". In these times, people could observe seven lights in the night sky wandering, changing position with respect to the background stars. Saturn was one of the 7 wanderers. This sundials design dates back to the Roman era when the planets where revered as Gods.
