Prague Astronomical Clock

Yet another memorable astronomical clock of Europe is in the main square of the old town of Prague. A wonderful piece of engineering, it is the third oldest clock and the only one that functions well even today. It was installed in 1410.

The clock mechanism is interesting. It is composed of three main components:
The astronomical dial, which represents the position of the Sun and Moon in the sky and displays various astronomical details. “The Walk of the Apostles”, is a clockwork hourly dramatic show of figures of the Apostles and other moving sculptures. One of them is a figure of Death (represented by a skeleton) striking the time… warning everyone that they are an hour closer to death.

The third component is a calendar dial with medallions representing the months. Here is a short video of the clock.
