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"?

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.

Sundials and obelisks Ancient Egyptian obelisks, built around 3500 BC, are also among the oldest ghost clocks. The oldest known sundial comes from Egypt. It dates from around 1500 BC. Candle clocks The first mention of candle clocks comes from a Chinese poem written in 520 AD. According to this poem, the graduated candle, whose burning rate was measured, was a means of determining the time of night. Similar candles were used in Japan until the early 10th century. Hourglass Hourglasses were the first reliable, reusable, reasonably accurate and easily manufactured time measuring devices. From the 15th century onwards, hourglasses were mainly used to tell time at sea. An hourglass consists of two glass spheres connected vertically by a narrow neck that allows a controlled flow of material, usually sand, from the upper sphere to the lower. Hourglasses are still used today. They were also introduced for use in churches, industry and the kitchen. Candle clocks were another timekeeping device used in the ancient world, from China to England to Mesopotamia. Chronometers were developed in places like India and Tibet and the hourglass (which was widely used throughout Europe) came a little later.

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.

The privilege of the aristocrats at the beginning and for hundreds of years, the popularisation of jewellery boxes did not begin until the beginning of the 19th century following the industrialisation of many manufacturing processes which became factories and of course production lines. Thus, more modest families could afford jewellery boxes to preserve jewellery and other precious items passed down from parents, grandparents, great-grandparents or any other family member in a more permanent way. However, some objects inherited from a distant and not always shameful past are frowned upon today, such as ivory jewellery. It should also be pointed out that there are simple jewellery boxes without compartments and other jewellery boxes with many compartments, of course the prices vary greatly. There are also musical jewellery boxes. Today we find music boxes at all prices, music boxes that have become gadgets that many people know. Music boxes were the only instrument that allowed you to listen to a melody if you were not a musician! The music box had its heyday in the early 19th century. The object we offer is made of faux leather in a rectangular shape to escape the standardisation of jewellery boxes, "Made in China". You have the possibility to find decorations for almost every imaginable event: Mother's Day, Valentine's Day, birthdays, and of course we can apply your photo on the lid of this jewellery box.
