These sundials date as far back as 5,000 BC. However, the first evidently purpose-built sundial was not constructed until 800 BC. The obelisks built by the Egyptians and the Babylonians served more than their decorative purpose. They used the position of the shadow to estimate what time of day it was.
Why was the sundial used to measure time?
The sundial was a more accurate tool to estimate the time by using the Sun. The sundial is the oldest known device for the measurement of time and the most ancient of scientific instruments. It is based on the fact that the shadow of an object will move from one side of the object to the other as the sun “moves” from east to west during the day.
When did the ancient Egyptians invent the sundial?
Ancient Egyptians are credited with the invention of sundials. Although obelisks were built as far back as 3500 B.C., perhaps the earliest portable sundial that has survived, often referred to as an Egyptian shadow clock, became popular around 1500 B.C.
