The Corpus Clock Travel Guide

The Corpus Clock stands prominently at street level on the exterior of the Taylor Library at Corpus Christi College, Cambridge. Conceived and funded by John C. Taylor, a distinguished alumnus and inventor, the clock was unveiled in September 2008 by renowned physicist Stephen Hawking. This public monument was created to commemorate the 500th anniversary of the college and has since become an iconic symbol of Cambridge’s blend of tradition and innovation.

Crowning the clock is the Chronophage, a mechanical grasshopper-like creature whose name means 'time-eater' in Greek. This unsettling sculpture appears to consume each passing second, with its mouth opening and closing and spiky legs crawling around the clock face. The Chronophage serves as a vivid reminder of the relentless, inescapable passage of time and the inevitability of mortality.

Unlike conventional clocks, the Corpus Clock has no hands or numbers. Instead, it features a 1.5-meter diameter gold-plated face with 60 notches radiating from its center. Time is displayed through three concentric rings of blue LED lights that indicate hours, minutes, and seconds. The clock’s movement is deliberately irregular, speeding up and slowing down before resetting, symbolizing the uneven experience of time in human life. This dynamic display challenges traditional perceptions of time as steady and uniform.

The clock’s construction was a complex endeavor, involving over 200 people and costing around £1 million. Part of its engineering was developed in a secret Dutch military research facility. Despite its intricate mechanics, the clock is powered only by a small electric motor for the LEDs, relying on purely mechanical components for its timekeeping. The Corpus Clock is recognized as one of Time magazine’s Best Inventions of 2008, celebrated for its fusion of art, science, and philosophy.

Situated at the busy junction of Trumpington Street and Bene't Street, overlooking King’s Parade, the clock is easily accessible and draws a steady stream of visitors. It stands in stark contrast to the surrounding historic architecture, offering a modern, thought-provoking spectacle amid Cambridge’s ancient streets. The Latin inscription beneath the clock, "Mundus transit et concupiscentia eius" (The world passeth away, and the lust thereof), deepens the clock’s meditation on time and existence.

Visitors are often captivated by the clock’s hypnotic movement and philosophical undertones. The Corpus Clock invites reflection on time’s fleeting nature and the human condition. Its LED light patterns and occasional special performances on notable days add layers of intrigue. As a free, outdoor attraction, it offers an accessible cultural highlight in Cambridge’s rich intellectual landscape.
