The name derives directly from the original Greek *klepsydra*, which literally means "water-stealer." It was, however, the first timekeeping instrument independent of astronomical observations. One of the oldest examples was discovered in the tomb of the Pharaoh Amenhotep I, dating back to the 15th century BC.
In Greece, the use of the clepsydra was introduced in 325 BC in the form of truncated-cone-shaped stone vessels that allowed water to flow out of a hole in the bottom at a constant rate.
Other clepsydrae were cylindrical or cup-shaped and were slowly filled by a steady stream of water. Markings on the vessel's inner surface indicated the passage of hours as the liquid level rose. Another version consisted of a metal container with a hole in the bottom; when placed to float inside a larger vessel, it would sink after a specific amount of time. This system remained in use in North Africa until the 20th century. These clocks were generally used at night rather than during the day, when more accurate sundials were available.
