The Prague Astronomical Clock is a set of mechanisms that every watch lover should see.
If you haven't had the opportunity to meet, go and see yet, one of the astronomical clocks that deserve to be on the "must-see list" is the Prague Astronomical Clock. This mechanical marvel, also known as "Prague Orloj" and which is the third oldest astronomical clock, still works. It is not easy to create such a clock with the technology of that day. This is why the lower calendar dial of the clock, which was started to be built in 1410, was added around 1490. The magnificence of the clock is supported by the gothic sculptures added during the same period, wooden sculptures added between 1629 and 1659, and the 'Apostle' sculptures included in them between 1787 and 1791.
As you know, astronomical clocks show the relative positions of the Sun, Moon, constellations, and planets. Located in the Old Town Square, this famous clock tells the time, shows the date, gives information about the Zodiac, and offers a visual feast every hour, along with many clues about medieval astronomy.
The position of the Sun and Moon in the sky and various other astronomical details are displayed on the dial of the astronomical clock, which is a symbol of the city. The fixed main background of the dial holds plenty of information for those who can read it. The outermost ring of the background is a series of glyphs representing ancient Czech times. Approaching the center, Roman numerals are seen, as in most traditional clocks, they are used to indicate the 24-hour time. Various shades of blue and red on the main plate indicate events such as sunrise, dusk, daytime, night, as well as various geographic information such as tropical and equator. The earth is located in the center of the dial and the Zodiac ring is on the main astrolabe and is lined up counterclockwise.
The Prague Astronomical Clock, besides being a clock, accompanies many works of art. Fixed sculptures are representing four evil deeds next to the clock, and four goodness-virtues beside the calendar dial.
Just above the clock are two blue doors that open to reveal the "The Walk of the Apostles". Every hour between 9.00 and 21.00 in the morning, the bell in the hand of the skeleton symbolizing death rings, and the march begins.
Below the main astrolabe and the clock is the calendar dial with various painted medallions, each representing the calendar months. Each figure represents individual months and seasons. The area closer to the center features a series of pictures, each representing the zodiac signs.
