Solar and Lunar Timekeepers

This set includes an astronomical ring dial, invented in the 1600s, and a nocturlabe, invented in the 1500s. These hanging timepieces help you always know what time it is even if you aren’t interested in pulling out your phone and prefer the time before the digital age. The astronomical ring works during the daytime by determining where the sun is based on where the ray of light hits the dials. The nocturlabe, on the other hand, measures the position of the stars in the Big and Little Dippers respectively to tell the time. Despite their obsolescence by the 1700s, these are working models that you can use to remember the past.
