Greek inventor and mathematician Ctesibius (Ktesibios,Tesibius; Κτησίβιος), probably the first head of the Museum at Alexandria, invented the first artificial automatic self-regulatory system by designing an improved water clock or clepsydra (water thief) that required no outside intervention between the feedback and the controls of the mechanism. More accurate mechanical clocks using falling weights instead of water appeared in the fourteenth century, and the ingredients for the modern clock were in place when Galileo described the pendulum in the sixteenth century.

Ancient alarm clock used by the Egyptians was made by a greek engineer, physicist and mathematician Ctesibius (285–222 BCE) who lived in Alexandria, Ptolemaic Egypt. (Peters, Arno: Synchronoptische Weltgeschichte. During his time as a barber, he invented a counterweight-adjustable mirror. This last vessel was mostly enclosed, but it had thin openings, making it whistle like a tea kettle when it filled up quickly. Above picture is The Obelisk of Theodosius at Istanbul.

When opened, it was found to contain an exquisitely carved wall clock, in the "chalet" style. His other inventions include the hydraulis, a water organ that is considered the precursor of the modern pipe organ, and improved the water clockor clepsydra ("water thief"). He is best known for his three inventions – the suction pump, the water clock, and the hydraulis, a musical instrument that is the ancestor of the pipe organ. The Ctesibius Clock was a gift - or perhaps a warning - received by the Mayor, Tullia Giovanna, in 1753. Ctesibius first fashioned orifices of gold or other substances which would not be worn by the action of water and did not collect dirt. When the burning incense burnt and broke the threads, the bells fell down at preset interval to give an alarm. Time was tracked by a water clock. Having guaranteed an uninterrupted water flow into the first chamber of the clock, Ctesibius then devised a way to keep the water level in that chamber constant. However, when the Mayor examined the clock further, she realised that it was less traditional than it at first appeared; instead of the normal pair of songbirds who whould appear on each hour, the clock contained small wooden statues of a pair of wolves instead. Take your favorite fandoms with you and never miss a beat. When the water got high enough to fill the tube and start spilling over, all of it at once was siphoned off into yet another vessel.

Ctesibius (285–222 BCE) was the Father of Pneumatics, a branch of engineering that makes use of gas or pressurized air. Ctesibius was probably the first head of the Museum of Alexandria. He is best known for his three inventions – the suction pump, the water clock, and the hydraulis, a musical instrument that is the ancestor of the pipe organ. The Ctesibius Clock was a gift - or perhaps a warning - received by the Mayor, Tullia Giovanna, in 1753. It is said (possibly by Diogenes Laërtius) that his first career was as a barber. https://wolfendorf.fandom.com/wiki/Ctesibius_Clock?oldid=4962. Some even describe him as an ancient genius. The water clock was invented with the purpose of tracking time. Some even describe him as an ancient genius. Very little is known of his life, but his inventions were well known. Greek inventor and mathematician Ctesibius (Ktesibios,Tesibius; Κτησίβιος), probably the first head of the Museum at Alexandria, invented the first artificial automatic self-regulatory system by designing an improved water clock or clepsydra (water thief) that required no outside intervention between the feedback and the controls of the mechanism. Detail of the pedestal: Theodosius I offers laurels of victory; we can see the water organ of Ctesibius, in the lower right-hand corner.

Attached to the box was a short note, written in a strange red ink of some kind, with the words "On the New Moon it starts. The Alarm Clock was invented in the time of Ancient Greece. The idea of a alarm clock came from a engineer called Ctesibus. He made the water clock make sounds like a whistling bird, bells, puppets, and other gadgets. However, it was not until 1657 that the Dutch physicist Christiaan Huygens showed how a pendulum could be used to regulate a clock, and only then was the first mechanical clock more accurate than that of Ctesibius, invented some 1800 years previously. Mathematical Models of Water Clocks (PDF File), Hydraulic Clock of Archimedes, E. Widemann, F. Hauser, Nova Acta, Deutsche Akademie der Naturforscher, 1918, Book 9, Sundials and Waterclocks, Vitruvius, I will tell you in the course of my speech, if you care to hear and if the water in the water-clock holds out. Early in the evening of the 1st of June - the night of the new moon - as Tullia was returning to the Mayor's House to prepare for the town meeting she had called following the most foul murder of Lord Joshua Ravenclaw, she found a large box left on her doorstep. On the Full Moon, your time runs out.". He is best known for his three inventions – the suction pump, the water clock, and the hydraulis, a musical instrument that is the ancestor of the pipe organ. Plato’s invention was successful and people who used his alarm clock woke up on time. The Romans also developed mechanized clepsydras, though their complexity accomplished little improvement over simpler methods for determining the passage of time.

Plato was not very happy with his student at the academy kept oversleeping. Ctesibius was a great scientist ahead of his time. After displaying the clock at the town meeting, the Mayor stored it in the attic of the Mayor's House, rather than put it on any wall, for the macabre juxtaposition of the quaint traditional carving and the ominous motto quite frankly scared her. In ancient China, candles and sticks of incense that burn down at approximate predictable speeds were also used as to estimate the passage of time and act as ancient alarm clock. But, Plato (428–348 BCE), a greek philosopher constructed his own version of an alarm clock with vessels much ahead of Ctesibius.

Ctesibus made a system of dropping peddles on a gong to make a sound which is the first alarm clock. Carved into the clockface was a Latin motto; "a fronte praecipitium, a tergo lupi".

For more than 1,800 years the clepsydra was the most accurate …
