The automatic servant of Philon from the 3rd century BC, is seen at Kotsanas Museum of Ancient Greek Technology in Athens, Greece. It is the focal point of an exhibition of more than 100 inventions that highlight the vast extent of Ancient Greece's technological legacy and also features an analogue computer, an alarm clock and automatic fire doors.

"By just opening up the hood of a modern car, you will see bolts and nuts, screws, automatic pilots. All of these were just some of the inventions (pioneered)... by the ancient Greeks that were the building blocks of complex technology," said exhibition director Panagiotis Kotsanas.The exhibits are explained with audio-visual material and detailed diagrams, and many are interactive. The automatic doors of Heron of Alexandria were considered a miracle of the gods. Installed in a temple, they opened when a fire burned on its altar, to the awe of those spectating.Viewed as a precursor of the computer, the 2,000-year-old Antikythera mechanism forecast astronomical and calendar events using gears and dials.

The philosopher Plato's alarm clock used a hydraulic system of ceramic jugs filled with water to 'ring' with a chirping sound at the desired time.

Qanat was the only water source for agriculture and irrigation in arid area so a just and fair water distribution was very important. Therefore, a very fair and clever old person was elected to be the manager of the water clock or mir āb, and at least two full-time managers were needed to control and observe the number of hours and announce the exact time of the days and nights from sunrise to sunset because shareholders usually divided between day and night owners.[30]The Persian water clock consisted of a large pot full of water and a bowl with a small hole in the center. When the bowl became full of water, it would sink into the pot, and the manager would empty the bowl and again put it on the top of the water in the pot. He would record the number of times the bowl sank by putting small stones into a jar.[30] The place where the clock was situated and its managers were collectively known as the khane pengān. Usually this would be the top floor of a public house, with west- and east-facing windows to show the time of sunset and sunrise. The Zibad water clock was in use until 1965,[27] when it was replaced by modern clocks.[26]Greco-Roman worldAn early 19th-century illustration[31] of Ctesibius's (285–222 BC) clepsydra from the 3rd century BC. The hour indicator ascends as water flows in. Also, a series of gears rotate a cylinder to correspond to the temporal hours.A modern reconstruction of Ctesibius' hydraulic clock (clepsydra), at the Kotsanas Museum of Ancient Greek Archaeology in Athens.The word "clepsydra" comes from the Greek meaning "water thief".[32] The Greeks considerably advanced the water clock by tackling the problem of the diminishing flow. They introduced several types of the inflow clepsydra, one of which included the earliest feedback control system.[33] Ctesibius invented an indicator system typical for later clocks such as the dial and pointer.[34] The Roman engineer Vitruvius described early alarm clocks, working with gongs or trumpets.[34] A commonly used water clock was the simple outflow clepsydra. This small earthenware vessel had a hole in its side near the base. In both Greek and Roman times, this type of clepsydra was used in courts for allocating periods of time to speakers. In important cases, such as when a person's life was at stake, it was filled completely, but for more minor cases, only partially. If proceedings were interrupted for any reason, such as to examine documents, the hole in the clepsydra was stopped with wax until the speaker was able to resume his pleading.[35]Clepsydrae for keeping timeSome scholars suspect that the clepsydra may have been used as a stop-watch for imposing a time limit
