Old Town Hall, Prague

The fantastic clock on the Old Town Hall of Prague was made by Magister Hanus, the university astronomer. The big outer ring, with Arabic numbers, relates to the Bohemian 24-hour day (which began at sunset, and the face with Roman numerals to the motions of the stars and planets. The smaller ring shows the position of the sun and moon in the Zodiac. At the top, at each hour, the mechanical figures of the Apostles, Death and allegorical Virtues process out of one opening and into another.

The mechanism of the clock was renewed in the 16th century and its face had been much restored in later times.
