![]() ![]() The water clock, however, was not without its flaws. Depending on the type of speech or trial that was going on, different amounts of water would be filled into the vessels. Apart from timing their speeches, the water clock also prevented their speeches from running too long. Some Athenian sources indicate that the water clock was used during the speeches of various well-known Greeks, including Aristotle, Aristophanes the playwright, and Demosthenes the statesman. One of the uses of the water clock in Greece, especially in Athens, was for the timing of speeches in law courts. Based on the amount of water that dripped from the first container, one was able to tell how much time had passed.Īround 325 BC, water clocks began to be used by the Greeks, who called this device the clepsydra (‘water thief’). Unlike the latter, the former’s measurements were in a second container instead. An inflow water clock followed the same principle as an outflow one, i.e. Observers were able to tell time by measuring the change in water level. The container was filled with water, which was allowed to leak out at a steady pace. In an outflow water clock, the inside of a container was marked with lines of measurement. In the ancient world, there were two forms of water clocks: outflow and inflow. Although no one is certain when or where the first water clock was made, the oldest known example is dated to 1500 BC, and is from the tomb of the Egyptian pharaoh Amenhotep I. To compensate for these shortcomings, the water clock was invented. Sundials would, of course, only function when there was sunlight, and they could not maintain a constant division of time. This method of measuring time, however, had its flaws. In the ancient world, for instance, sundials were commonly used. ![]() Prior to the invention of such battery-operated gadgets, time-keeping was done quite differently. One just simply needs to glance at a watch, clock, or mobile phone to know the exact time, even down to the nearest second. Today, the ability to keep track of time seems to be taken for granted. ![]()
