Astronomical clocks have always held a fascination for people with a keen interest in both history and the wonders of the universe. One such remarkable timepiece is the oldest astronomical clock in Prague, located in the heart of the city’s Old Town Square. This intricate clock not only tells time but also displays various astronomical features, making it a true marvel of medieval engineering.

The Astronomical Clock’s History

The Prague Astronomical Clock, also known as the Orloj, was first installed in 1410 by clockmaker Mikuláš of Kadaň and astronomer Jan Šindel. Over the centuries, it has been meticulously maintained and restored, allowing visitors to experience its magic to this day.

Reading the Time

At first glance, deciphering the time on this ancient device may seem challenging. However, with a little understanding of its unique design, you can easily read it:

  1. Hour Hand: The large outermost hand indicates the current hour. Note that it follows Old Czech Time which divides daylight into 12 equal parts during summer and winter.
  2. Minute Hand: The smaller hand located inside the hour hand displays minutes in regular increments from 0 to 60.

This combination of hands allows you to read both hours and minutes accurately on this remarkable clock.

Astronomical Features

The Prague Astronomical Clock doesn’t just tell time; it also showcases various astronomical elements:

  • Zodiac Ring: Surrounding the clock’s face is a zodiac ring featuring all twelve signs of the zodiac. This celestial display adds an astrological touch to this ancient timepiece.
  • The Sun: Look for the golden sphere located at the center of the clock.

    As the hour hand moves, it also indicates the position of the sun in the sky.

  • Moon Phases: Positioned to the side of the clock face is a small sphere representing the moon. It shows different phases throughout its lunar cycle.

By observing these additional astronomical features, you can further appreciate the craftsmanship and ingenuity behind this medieval marvel.

The Astronomical Clock’s Show

Aside from its timekeeping and astronomical features, the Prague Astronomical Clock also offers a captivating show every hour. As the clock strikes, various mechanical figures come to life, including twelve apostles that parade through two windows above the clock face, symbolizing passing time and mortality.
