French historian Jacques le Goff points to the 13th century when the first mechanical clock saw the light of day as a turning point in our existence. – Even we went into the dark Middle Ages when the church buried all the research including the concept of time it was not possible to put the cat back in the sack.
The first mechanical clocks, employing the verge escapement mechanism with a foliot or balance wheel timekeeper, it became the standard timekeeping device until the pendulum clock was invented in 1656.
We could quickly after this make watches that were astonishingly accurate. – Fascination for watches is not just about being able to correctly show time, but it is a control over life and death.
The first public clock that showed the hours of the day came in 1336 at the Church of San Gottardo in Milan, Italy. – As the clock became a part of everyday life, it was he who could control time who controlled politics. Where should the city bell be, the town hall, the palace or the church. Added value was built into the presentation of time, the clock slowly but surely became a work of art.
An agreement that does not have an indication of time is by definition not valid, clocks are now everywhere and it is a matter of course in all contexts.
