The Strasbourg Cathedral Astronomical Clock 1xPiP

A remarkable trouvaille is the astronomical clock in the southern transept.
In 1567, the three mathematicians Michael Herr, Christian Herrlin and Nikolaus Prugner, were commissioned to build an astronomical clock, but their design was never carried out; Conrad Dasypodius, also a professor of mathematics and a pupil of Herrlin, produced the final plan, which was carried out by the brothers Josias and Isaak Habrecht.
This clock, already equipped with astronomical displays, calendar and planetarium, was completed in 1574 and ran until 1789.
