Detailed Guide to Reading the Astronomical Clock

The Prague Astronomical Clock, or Orloj, is a marvel of medieval technology that offers more than just the time of day. It displays astronomical and calendrical information through a series of intricate dials and moving figures. This guide will break down each component, explaining how to read and interpret the various features of the clock.

Step-by-Step Instructions to Read the Time

Understanding the time on the Astronomical Clock is about more than just looking at the hour hand. The clock face is a complex display of circles and dials that represent both standard and astronomical time.

Outer Ring: This is where you find the standard 24-hour time, which is unusual as it uses a fixed hand that points to the rotating outer ring marked with Roman numerals.

Bohemian Hours: Inside the outer ring, the time from sunrise to sunset is divided into 12 hours, which change length with the seasons. These hours are indicated by a secondary ring that rotates once every 24 hours.

Decoding Additional Features

The Astronomical Clock's allure also lies in its depiction of astronomical phenomena and its representation of a medieval worldview.

Zodiac Ring: The zodiac ring moves to show the position of the sun on the ecliptic, correlating to the astrological sign it is currently passing through. Understanding this can tell you about the length of daylight and key astronomical dates.

Sun Hand: This golden hand extends from the center and travels around the zodiac ring, pointing at the current sun's position. It's not just decorative; it provides a visual representation of the sun's path through the sky.

Moon Sphere: Opposite the sun hand, the moon sphere shows the current phase of the moon. It rotates on its axis, showing a mirror-like reflection to indicate the moon's waxing and waning.

For those intrigued by celestial mechanics demonstrated by the clock, a visit to the Štefánik Observatory can deepen your appreciation for astronomy. Located atop Petřín Hill, the observatory offers a hands-on experience with telescopes and exhibits that echo the astronomical principles seen in the Orloj.

Calendar Dial: Located below the main clock, this dial represents the months, showcasing medallions for each month, along with major celebrations and saint's days.

Understanding the Movements of the Apostles

Every hour, a small trap door above the clock opens and the Twelve Apostles parade past the window. Each figure appears, blessing the audience and moving synchronously with a symbolic artifact in hand. This not only marks the hour but also connects daily timekeeping to spiritual reminders.

The Clock's Legends and Lore

The Prague Astronomical Clock, or Orloj, is shrouded in mystery and steeped in legend, making it as much a monument to folklore as it is to timekeeping. The stories surrounding the clock are a fascinating blend of history, myth, and cultural significance, illustrating the deep roots of this medieval masterpiece in the imagination of Prague.

Myths and Legends Associated with the Clock

One of the most enduring legends tells of the clock's maker, Master Hanuš, who was allegedly blinded by the city councilors to prevent him from replicating his masterpiece elsewhere. According to legend, in revenge, Hanuš tampered with the clock, ensuring that anyone who tried to repair it would either fail or suffer misfortune. This tale, while likely apocryphal, underscores the clock's significance and the awe it has inspired over centuries.

Another popular myth involves the figure of the skeleton, which represents Death, striking the hour. It's said that during times of plague or great suffering, the skeleton's animation would become eerily pronounced, as if it were responding to the city's misfortunes.

The Curse of the Clock and Its Maker

The curse associated with the Astronomical Clock adds a layer of mystique. It is said that the city will face dire consequences if the clock is neglected or its operation interrupted. This legend was particularly poignant during World War II and the 2002 floods when the clock stopped due to damage. Each event was followed by hardship for Prague, reinforcing the superstition among locals and visitors alike.

Interpretations of the Moving Figures

Each of the animated figures on the clock carries symbolic weight:

The Skeleton (Death): Rings a bell to the chime of the hour, reminding viewers of their mortality.
The Turk: Represents pleasure and entertainment, shaking his head in disapproval at the passing time.
The Miser with a Bag of Gold: Symbolizes greed and wealth, a stark contrast to the inevitable fate represented by the skeleton.
Vanity with a Mirror: Reflects the folly of narcissism and self-obsession.

These figures parade every hour, providing a morality play that cautions viewers against various vices and the inexorable passage of time.
