A #sundial is a device that indicates time by using a light spot or shadow cast by the position of the #Sun on a reference scale.
The earliest household #clocks known, from the archaeological finds, are the sundials (1500 BCE) in Ancient #Egypt and ancient Babylonian astronomy.
The #ancient #Greeks developed many of the principles and forms of the sundial. Sundials are believed to have been introduced into #Greece by Anaximander of Miletus, c. 560 BCE.
The #Romans adopted the Greek sundials, and the first record of a sundial in #Rome is in 293 BCE according to #Pliny.
