Puzzle Praha (Prague) Orloj (Astronomical Clock)

The Praha Orloj or Prague Astronomical Clock, is a medieval astronomical clock located in Prague, the capital of the Czech Republic. The clock was first installed in 1410, making it the third-oldest astronomical clock in the world and the oldest clock still operating. The Orloj is mounted on the southern wall of Old Town Hall in the Old Town Square. The clock mechanism has three main components — the astronomical dial, representing the position of the Sun and Moon in the sky and displaying various astronomical details; statues of various Catholic saints stand on either side of the clock; "The Walk of the Apostles", a clockwork hourly show of figures of the Apostles and other moving sculptures, notably a figure of a skeleton, representing Death, striking the time; and a calendar dial with medallions representing the months. According to local legend, the city will suffer if the clock is neglected and its good operation is placed in jeopardy; a ghost, mounted on the clock, was supposed to nod its head in confirmation. According to the legend, the only hope was represented by a boy born on New Year's night.
