| Prague Orloj - Wikipedia, the free encyclopedia (908 words) |
 | The Orloj is composed of three main components: the astronomical dial, representing the position of the Sun and Moon in the sky and displaying various astronomical details; "The Walk of the Apostles", a clockwork hourly show of figures of the Apostles and other moving sculptures; and a calendar dial with medallions representing the months. |
 | The oldest part of the Orloj, the mechanical clock and astronomical dial, dates back to 1410 when it was made by clockmaker Mikulas of Kadan and Jan Sindel, the latter a professor of mathematics and astronomy at Charles University. |
 | In 1552 it was repaired by Jan Taborsky, clockmaster of Orloj, who also wrote a report on the clock where he mentioned Hanus as maker of the clock. |
