time?​

Answer 1

Answer:

One of the earliest of all devices to tell time was the sundial. The sundial is looked on as being a form of sun-powered clock. Ancient civilizations such as the Sumerians did have this knowledge, but when the culture died, knowledge was lost along with many other aspects of the civilization unfortunately. One thing that is known is this. It was the ancient Egyptians who did come up with a form of system to divide the day up into parts. These parts were a whole lot like hours in description. The Egyptians constructed obelisks, which were four-sided and well tapered monuments, and they were geographically located in certain places. These obelisks were believed to have been constructed around 3500 BC and a shadow would be cast by the obelisk as the sun made it’s way across the sky. This obelisk would be marked out in certain sections to see the two halves of the day. There was another more advanced shadow clock or sundial in use by the ancient Egyptians around 1500 BC. This shadow clock or sundial permitted one to measure the passage of hours within a day
