Midsummer Chronophage

Hypnotically beautiful yet deeply disturbing, Dr John C Taylor’s Midsummer Chronophage clock is both a work of art and a unique way of displaying time.

Time flies when we’re having fun. Or, as Dr John C Taylor OBE, creator of the Midsummer Chronophage explains:

‘It was Einstein who said Time was relative. When asked for an example, he paused and then said, “If you think about it, an hour spent on a park bench with a pretty girl passes in a moment, but a moment sat on a hot stove seems like an hour."’

What is the Chronophage?

It was through thinking about Einstein’s theories on time that Dr Taylor conceived the idea for the Chronophage – from the Greek chronos (time) and phage (eater) – a mythical, insect-like creature which controls a magnificent golden clock.

Dr Taylor’s thoughts were triggered by the realisation that time is both eternal at a universal level yet extremely limited at a personal level, and that the time we have spent cannot be regained – almost as if it has been eaten up by a relentless, menacing creature…

Battle-hardened and leathery, the Chronophage is that creature, consuming time by walking steadily above a huge clock face, pulling the minutes along with a rocking motion, its jaws snapping shut every 60 seconds as it swallows up another minute. Yet occasionally, the creature seems to play a trick on us, speeding up or slowing down the passage of time.

How does the clock work?

The form of the Chronophage is inspired by and celebrates the work of the 17th century horologist John Harrison. Harrison is famous for his portable sea clocks, invented to solve the problem of measuring longitude at sea. Harrison created a rocking mechanism for controlling clocks which he called a ‘grasshopper escapement’.

Dr Taylor turned the underlying mechanical workings of Harrison’s ‘grasshopper escapement’ inside out, so that the teeth of the escape wheel, normally concealed within the clock, rotate around the outside of the massive, gold-plated face, moved along by the feet of the unsettling, unstoppable creature, now placed on the outside of the device for all to admire and fear.

How does the clock display the time?

The clock face has no hands or numbers. Instead it shows three rings of light – the first clock design in the world to display time in this way. The outer ring shows seconds, the middle ring minutes and the inner ring hours and quarter hours. Every second, the light rushes rapidly around the outer ring, then appears to pause for a moment as the pendulum reaches the limit of its swing. The sense of time racing away is very evident.

Although the rings of lights appear to be flashing on and off, the lights are actually on all the time. The escape wheel drives three concealed stainless steel rings, each with a ring of slits, in front of circular banks of LED lights in the core of the clock. As these rings rotate, the appropriate slits align so only one light in each ring is visible at any moment. Day and night are like that in reality: the sun does not go out, it is simply obscured.

You see how the Chronophage was made in this YouTube video.

In this video, Dr Taylor explains how the Chronophage works.

How does the Chronophage tell ‘relative time’?

Despite the precision of scientific measurement, time is unpredictable. We use expressions like ‘time standing still’ or ‘time running away’. The Chronophage is the first serious clock that has attempted to take account of this.

Just occasionally (not very often), it will seem to stop altogether, or to have moved rapidly forward so imperceptibly that one can hardly see what has happened. The pendulum suddenly seems to freeze. Sometimes we could almost swear that time went backwards. These illusions appear to happen at random – yet the clock returns to accurate time every fifth minute.

As Dr Taylor explains:

‘Once you have seen the Chronophage, all other clocks will seem rather boring – all they do is tell the time.’

Midsummer Chronophage fact file

Created by: Dr John C Taylor OBE
Chronophage series: The Midsummer Chronophage is the second clock in the Chronophage series. The first, the Corpus Clock, hangs at Corpus Christi College, Cambridge, and was unveiled by Professor Stephen Hawking in 2008. A third, featuring a Chinese dragon, is set for Shanghai. No two will be the same and only a very limited number will ever be made.
Made from: Gold and rhodium plating, stainless steel, electro-mechanical components
Made by: Over 300 artists, scientists and engineers were involved in the construction of the Chronophage. Each creature is uniquely created by sculptor and metalsmith Matthew Lane Sanderson.
Made in: The Midsummer Chronophage was completed in 2010 and took two years to build.
Dimensions: 3.3m x 1.5m x 0.5m
On display: The clock hangs in the Discoveries gallery, next to the Millennium Clock, until 12 May 2013
Did you know? Inventor Dr John C Taylor holds hundreds of patents for domestic appliances, thermostats and electrical equipment. His single most famous invention is the cordless kettle.

RBS Museum Talks

On Friday 6 July, American author Dava Sobel, author of Longitude and Galileo’s Daughter, will be in conversation with Dr John Taylor at the National Museum of Scotland. Find out more here.
