Right in front of you, on the corner where Bene’t Street meets Trumpington Street, look for a big golden wheel that seems to ripple like melted metal. And perched on top, a rather judgmental-looking creature with a nasty stare. Congratulations-you’ve found the Corpus Clock.
Now pause here, because Cambridge doesn’t usually do “street entertainment” like this. No marble lions, no noble kings on horseback. Instead, you get a mechanical monster that looks like it escaped from a slightly deranged scientist’s daydream-maybe even a Stephen Hawking nightmare. And that’s fitting, because the clock was unveiled in 2008 by Hawking himself. Not bad for a timepiece that looks like it’s always hungry.
The face-more like a giant disc-is stainless steel plated in 24-carat gold, about a meter and a half across. There are no hands and no numbers. Time shows up through little openings lit by blue LEDs, arranged in rings across the surface. But let’s be honest: the star of the show is above it. That black beast-half insect, half dragon-has unsettling eyes and sharp teeth. It’s called the Chronophage, which literally means “time-eater.” Every time it snaps its mouth, it “eats” one second. Listen closely and you may catch a metallic clack, almost like a growl, as if it’s chewing the clockwork of your life.
That chomping isn’t random; it’s part of the mechanism. The clock uses something called a grasshopper escapement. In plain English, an escapement is the part of a clock that releases energy in tiny, controlled steps so time can tick along. This particular design dates back to the 18th century and was invented by John Harrison. The Corpus Clock itself was created by John Taylor, who basically said, “Nobody understands how a grasshopper escapement works… so I’m putting it on display.” The result is the largest grasshopper escapement in the world-usually hidden inside antique clocks, but here it’s proudly out in the open, daring you to figure it out.
The Chronophage also blinks-quickly-using golden eyelids. Miss the moment and you’ll swear it never happened. The whole system is powered by an internal spring, ready to snap into motion, and below it all hangs a large, pristine pendulum that gives the performance a strangely grand, ceremonial feel.
Here’s the twist: it’s only truly accurate once every five minutes. The rest of the time, it acts moody-stopping suddenly, then racing ahead like it’s late for an exam. Taylor did that on purpose, as a reminder that life doesn’t move at a steady pace.
There’s even a Latin inscription: “Mundus transit et concupiscentia eius”-“The world passes, and its desires pass with it.” A cheerful little thought for your photo break.
This spot used to hold a Victorian bank, so the clock feels like a portal from sober old Cambridge into something delightfully sci-fi. More than 200 people helped create it-engineers, sculptors, jewellers, and even an official clock-keeper, just in case the monster gets a bit too peckish.
And yes, the Chronophage has “siblings”: similar clocks exist on the Isle of Man, including one with a dragon, and another on display in Douglas. But this is the original-melting gold, unpredictable accuracy, and all.
Stick around a moment. If you catch that rare double-blink, you’ll understand why no photo ever quite does it justice. It may eat seconds-but you get to keep the memory.
