13th century. Mechanical clocks began to develop. More than thirty testimonies are quoted from all over Europe at the end of the 13th century. In these texts we find the purchase of iron and weights and the acquisition of expensive clocks in monasteries, cathedrals and princely residences. These prices were often considerable: six marks for the clock of the monastery of Colmar in 1278, thirty pounds for that of Canterbury in 1292, fifty pounds for a simple repair or transformation of the clock of the cathedral of Sens in 1319. Gradually, the mechanical clock, whose movement is permanently maintained by a motorised weight, replaced the boring water clock that had to be constantly cleaned and filled or emptied. It seems that these early clocks - like the water clocks - were first intended to strike a particular time (e.g. alarm clock) and a little later to strike different times of the day; these clocks were "blind": they had no dial! The striking mechanism was operated by one or more pins on a wheel of the mechanism. This transfer of technology from hydraulic to mechanical power enabled the original purpose of the clock to be retained: the striking of a precise hour; this invention has therefore remained practically anonymous. It was not until a little later, in 1336, that an important innovation changed the history of clock-making: striking clocks.

1271: An imminent invention In 1941 Lynn Thorndike published a text of great importance for the history of mechanical clocks. This text - probably the earliest record of clocks, dated 13 April 1271 - concerns a commentary by Robert the Englishman, known as Robertus Anglicus, on The Sphere of Sacrobosco, which states in brief: That a wheel which can turn uniformly over twenty-four hours (to give the equinoctial hours) has not yet been perfected;but that the researches of the clockmakers were going in that direction. Robertus then proposed a wheel driven by a weight (without mentioning the problem of accelerating the movement of this system). This means that the mechanical clock was still in the research stage at that time. In simple terms, the year 1270 can be considered as the "earliest" date of this invention, which in scientific terms is called "terminus ante quem non". "The switch to mechanical time did not translate into language", it did not lead to a change in terminology: the term horologium was simply retained, as for water clocks. While the increasingly frequent references to "horologia" in parish registers suggest that a new technology was emerging at the time, the difficulty of interpretation is still at the forefront: are they hydraulic or mechanical "horologia"?

Clepsydra The water clock or clepsydra comes from the Greek word klepsydra, "thief of water", as it was used to limit the speaking time of lawyers during trials. It is thought to have been invented by the Egyptians in the 16th century BC. It is unreliable because the speed of the flow varies according to the temperature and pressure of the water, From the eleventh to the thirteenth century, documentary sources about water clocks are more numerous, but their interpretations remain ambiguous. For example, a manuscript mentions that in 1176 a college of church commissioners was established in Sens Cathedral to supervise the clock. In 1198, an ordinance stipulated that the men in charge of the clock during the week risked a fine if they did not wind the mechanism in time. In 1867, G. Juillot, a member of the city's Archaeological Society, concluded with certainty that the clock was "weighted and stamped". A. Ungerer, in a 1931 book, makes it a "mechanical clock", which is even more implausible (according to Gerhard Dohrn-van Rossum, notes 4-52); According to Jocelin de Brakeland, in 1198, during a fire in Bury St Edmunds Abbey, the monks rushed to the clock to fetch water. There is no ambiguity here, the 'horologium' is powered by water, so it is a hydraulic clock whose reservoir was large enough to put out the occasional fire.

History of the clock from its origins to the 16th century, The origins No mechanical clocks seem to exist before the fourteenth century, but several mentions in manuscript sources reveal some of the early history of the clock. The Latin word horologium, horologia, derived from the Greek [ὡρα, time and λέγειν, to say], has been used since Roman antiquity to refer to all time-indicating devices, but the use of this word for all time-measuring instruments hides from us the true nature of their mechanisms. The hydraulic clock A hydraulic clock is an ancient type of clock, which tells the time by allowing a liquid in a container to flow through a small hole. From the beginning, in ancient times, the liquid used was water, hence the name water clock. Later, mercury clocks could be found, especially in Arabic and Chinese writings, but this seems to be anecdotal. The first hydraulic clocks evolved from the simple clepsydra (see the France 2 television game show), to which a more or less sophisticated time indication was added (essentially a graduated scale); over the centuries, we have encountered different types of hydraulic clocks, monumental or not, with sophistications to animate skits, for example, or to strike a precise time.

Mechanical clock A mechanical clock is a time-measuring instrument that tells the time by an originally entirely mechanical action. It is based on the combination of three functions: a driving weight for the rotary movement, a regulator such as a balance wheel and a display (a graduated scale and hands). The mechanical clock is the successor to the various horologia. The Romans, and before them the Egyptians and Greeks, had already developed time-measuring instruments that demonstrated great astronomical knowledge. The invention of the mechanical clock can be placed around the 1300s and appeared in Western Europe at the end of the 13th century. Originally, it was a weight motor and foliot. A foliot is a vertical pendulum that controls the energy supplied to a wheel by a weight. The motion is then transmitted to gears that drive the movement of the hands. A weight suspended from a rope provides energy to the machine, while a system of rods and foliots periodically interrupts the fall of the weight. By placing the weights at each end of the foliot, the rhythm of the back and forth movements can be adjusted. The low precision of this mechanism, from 1 to 2 hours of deviation per 24 hours, renders the minute hand useless, and it will undergo a long evolution and an important diversification over the centuries.

Clocks Since time immemorial, people have tried to tame time. Thanks to scientific discoveries and technical innovations, the measurement of time has gradually been mastered. For thousands of years, people have measured time in a variety of ways, including following the movements of the sun with sundials, using water clocks, candle clocks and hourglasses. Our modern basic 60 time system, a clock with periods of 60 minutes and 60 seconds, dates back to 2000 BC in ancient Sumeria (the southernmost region of ancient Mesopotamia). History of clocks; "Time is money", they say, but the history of clocks is long and fascinating. The measurement of time is one of the earliest developments of mankind and time has changed greatly since ancient times. The birth of clocks to measure time: A clock is a time-measuring instrument that usually tells the time continuously. The word comes from the Latin horologium, "that tells the time", itself derived from the Greek ὡρολόγιον (formed from oρα, "time", and λέγειν, "to tell", λόγιον, "to tell"). Since ancient times, the Latin term 'horologium' has been used to refer to any instrument capable of indicating time, which has often led to difficulties in interpreting ancient texts. Thus, a sundial, a water clock, an astrolabe, a nocturlabe, a mechanical clock were called "horologia". A clock with a photo of your holiday by the sea, in the mountains or in the countryside.
