How Did People Tell Time Before Clocks? [Solved]
Sundials. The earliest known timekeeping devices appeared in Egypt and Mesopotamia, around 3500 BCE. Sundials consisted of a tall vertical or diagonal-standing object used to measure the time, called a gnomon. Sundials were able to measure time (with relative accuracy) by the shadow caused by the gnomon.2 Jul 2021
