And could its fateful ticking truly determine the future of Prague? Let’s find out!

Scientific and Astronomical Features of the Clock

Before uncovering the legend behind the Prague Astronomical Clock, let’s first talk about its most fascinating features. This iconic clock, the most famous astronomical clock in Prague, has been mesmerizing both locals and tourists since 1410, and it’s not just your average timekeeper. It’s a perfect mix of art, science, and a little bit of medieval magic. Here’s why this clock is so special:

Astronomical Dial: The clock has a cool dial that shows the sky, with the Earth at the center. It’s like a mini map of the cosmos! The dial also has Roman numerals, marking the time in a way that’s pretty different from our usual 12-hour clock. Plus, there’s a zodiacal ring that moves around, showing the position of the sun.
Sun and Moon Indicators:

Sun: A golden hand attached to the Sun icon moves around a circle, showing where the Sun is in the sky. It also tells the local time in Prague, uneven hours, and Old Czech Time.
Moon: A half-silver, half-black ball represents the Moon, showing its phase and position in the sky. The Moon’s arm moves faster than the Sun’s, reflecting its orbit around the Earth. This feature, added in the 1600s, works using gravity.

The Prague Astronomical Clock Show: Every hour, the clock does its famous “Prague Astronomical Clock Show.” Little doors above the clock open, and out come the Twelve Apostles, moving from left to right. You’ll also see figures of Vanity, Greed, Death, and Lust – they represent the vices of mankind. Death, in particular, rings a bell to remind you that time’s ticking! So, next time you’re in Prague, make sure you catch the show – it’s like watching history tick by, quite literally!
The Calendar Dial: Below the clock is a calendar that tells you the dates and the names of saints for each day. It’s pretty neat because it’s got images of the months too, giving a little extra flair to the whole thing.
Old Czech Time: There’s also something called Old Czech Time, which is a special time scale that the clock follows. Instead of counting hours like we do, it counts them backward from sunset. It’s a bit quirky, but that’s part of what makes this clock so unique!
