Prague, Czech Republic:

Prague’s Astronomical Clock (Czech: Pražský orloj), located in Prague’s Old Town, was first installed in 1410.  It is the third oldest astronomical clock in the world, and the only one currently in working order.

Zodiacal Ring

Inside the large black outer circle lies another movable circle marked with the signs of the zodiac which indicates the location of the Sun on the ecliptic. The signs are shown in anticlockwise order. In the photographs accompanying this article, the Sun is currently in Aries, and will be moving anticlockwise into Taurus next.

The displacement of the zodiac circle results from the use of a stereographic projection of the ecliptic plane using the North pole as the basis of the projection. This is commonly seen in astronomical clocks of the period.

The small golden star shows the position of the vernal equinox, and sidereal time can be read on the scale with golden Roman with numerals. Zodiac is on the 366 teeth gear inside the machine. This gear is connect to the sun gear and the moon gear by 24 teeth gear. – Wikipedia

  1. I have seen this clock. It really was very impressive and there is a story that the city authorities who commissioned it liked it so much that they blinded its creator after it was completed just so that he couldn’t make another one elsewhere. I don’t know if that is true but if it is then that was very ungrateful!

    I wouldn’t be surprised if it was true. After doing the underground tour, it is apparent that Czechs were very into torture.
