It is unimaginable to think of what such an object can contain in terms of technology and the work that it may have represented over the centuries.
"The Astronomical Clock of Notre-Dame de Strasbourg Cathedral is a masterpiece of the Renaissance, considered at the time to be one of the seven wonders of Germany.
In two phases, between 1547 and 1574, a second clock was built by the mathematicians Christian Herlin and Conrad Dasypodius5, the clockmakers brothers Josias (de) and Isaac Habrecht and the painter Tobias Stimmer. This clock was a planetary astronomical clock and therefore indicated the movement of the planets on an astrolabe. A perpetual calendar indicated movable feasts over a period of 100 years. Finally, upcoming eclipses were painted on panels.
The legend claims that the Magistrate, worried that the builder could build a similar work elsewhere, would have gouged out his eyes.
Dasypodius' clock stopped working shortly before the French Revolution and remained in this state until 1838.
From 1838 to 1843, the clock was transformed by Jean-Baptiste Schwilgué (1776-1856), a self-taught Alsatian who, after having been an apprentice watchmaker, became a mathematics teacher, checker of weights and measures, and finally an entrepreneur. Schwilgué had wanted to repair the clock from an early age and it remained a guiding force throughout his life.
The third and current clock basically consists of new mechanisms placed in the case of the second clock, dating from the 16th century. All the dials are also new, but the clock as a whole is conservative, in the sense that the functions of the Schwilgué clock differ little from those of the old clock, except for the procession of the Apostles which does not did not exist before. For the rest, there is always an equivalent."
