Prague Astronomical Clock
I love Prague. Having visited the city in spring (it was Easter) I wasn’t prepared for Prague in December. Christmas is something special there – I am not religious but it’s good to have some time to commemorate our humanity.

An astronomical dial is a form of a mechanical astrolabe, a device used in medieval astronomy. Alternatively, one may consider the Orloj (clock) to be a primitive planetarium, displaying the current state of the universe.
The astronomical dial has a background that represents the standing Earth and sky and surrounding it operates four main moving components: the zodiacal ring, an outer rotating ring, an icon representing the Sun, and an icon representing the Moon.
