Collection: Sundials

A sundial is a device used to measure time by using the position of the sun in the sky. It is one of the oldest known instruments for measuring time, dating back to ancient civilizations. A basic sundial consists of a flat plate or surface with a raised object called a gnomon (often a straight stick) sticking up from the center. As the sun moves across the sky during the day, the gnomon casts a shadow onto the plate.
