The Sundial is a device that tells time by using a flat surface and a long stick called a gnomon to turn the sun's reflection into a shadow that corresponds to a particular marking. The sundial was once used by many civilizations, including the likes of the Ancient Egyptians, the Babylonians, the Ancient Greeks, the Roman Empire, the Chinese, the Mayans, and the European countries during the Renaissance.
