In this perfect companion to London: The Biography, Peter Ackroyd once again delves into the hidden byways of history, describing the river’s endless allure in a journey overflowing with characters, incidents, and wry observations.
Thames: The Biography meanders gloriously, rather like the river itself. In short, lively chapters Ackroyd writes about connections between the Thames and such historical figures as Julius Caesar and Henry the VIII, and offers memorable portraits of the ordinary men and women who depend upon the river for their livelihoods. He visits all the towns and villages along the river from Oxfordshire to London and describes the magnificent royal residences, as well as the bridges and docks, locks and weirs, found along its 215-mile run. The Thames as a source of artistic inspiration comes brilliantly to life as Ackroyd invokes Chaucer, Shakespeare, Turner, Shelley, and other writers, poets, and painters who have been enchanted by its many moods and colors.
In his signature entertaining and informative manner, Ackroyd allows the reader to dip into chapters in his own spirit, or to follow the Thames from source to sea.
Illustrated with maps and photographs, THAMES is a vivid, highly original mosaic of life by and on the water.

The River as Fact
It has a length of 215 miles, and is navigable for 191 miles. It is the longest river in England but not in Britain, where the Severn is longer by approximately 5 miles. Nevertheless it must be the shortest river in the world to acquire such a famous history. The Amazon and the Mississippi cover almost 4,000 miles, and the Yangtze almost 3,500 miles; but none of them has arrested the attention of the world in the manner of the Thames.
It runs along the borders of nine English counties, thus reaffirming its identity as a boundary and as a defence. It divides Wiltshire from Gloucestershire, and Oxfordshire from Berkshire; as it pursues its way it divides Surrey from Middlesex (or Greater London as it is inelegantly known) and Kent from Essex. It is also a border of Buckinghamshire. It guarded these once tribal lands in the distant past, and will preserve them into the imaginable future.
There are 134 bridges along the length of the Thames, and forty-four locks above Teddington. There are approximately twenty major tributaries still flowing into the main river, while others such as the Fleet have now disappeared under the ground. Its "basin," the area from which it derives its water from rain and other natural forces, covers an area of some 5,264 square miles. And then there are the springs, many of them in the woods or close to the streams beside the Thames. There is one in the wood below Sinodun Hills in Oxfordshire, for example, which has been described as an "everlasting spring" always fresh and always renewed.
The average flow of the river at Teddington, chosen because it marks the place where the tidal and non-tidal waters touch, has been calculated at 1,145 millions of gallons (5,205 millions of litres) each day or approximately 2,000 cubic feet (56.6 cubic metres) per second. The current moves at a velocity between 1Ú2 and 23Ú4 miles per hour. The main thrust of the river flow is known to hydrologists as the "thalweg"; it does not move in a straight and forward line but, mingling with the inner flow and the variegated flow of the surface and bottom waters, takes the form of a spiral or helix. More than 95 per cent of the river's energy is lost in turbulence and friction.
The direction of the flow of the Thames is therefore quixotic. It might be assumed that it would move eastwards, but it defies any simple prediction. It flows north-west above Henley and at Teddington, west above Abingdon, south from Cookham and north above Marlow and Kingston. This has to do with the variegated curves of the river. It does not meander like the Euphrates, where according to Herodotus the voyager came upon the same village three times on three separate days, but it is circuitous. It specialises in loops. It will take the riparian traveller two or three times as long to cover the same distance as a companion on the high road. So the Thames teaches you to take time, and to view the world from a different vantage.
The average "fall" or decline of the river from its beginning to its end is approximately 17 to 21 inches (432 to 533 mm) per mile. It follows gravity, and seeks out perpetually the simplest way to the sea. It falls some 600 feet (183 m) from source to sea, with a relatively precipitous decline of 300 feet (91.5 m) in the first 9 miles; it falls 100 (30.4 m) more in the next 11 miles, with a lower average for the rest of its course. Yet averages may not be so important. They mask the changeability and idiosyncrasy of the Thames. The mean width of the river is given as 1,000 feet (305 m), and a mean depth of 30 feet (9 m); but the width varies from 1 or 2 feet (0.3 to 0.6 m) at Trewsbury to 51Ú2 miles at the Nore.
The tide, in the words of Tennyson, is that which "moving seems asleep, too full for sound and foam." On its flood inward it can promise benefit or danger; on its ebb seaward it suggests separation or adventure. It is one general movement but it comprises a thousand different streams and eddies; there are opposing streams, and high water is not necessarily the same thing as high tide. The water will sometimes begin to fall before the tide is over. The average speed of the tide lies between 1 and 3 knots (1.15 and 3.45 miles per hour), but at times of very high flow it can reach 7 knots (8 miles per hour). At London Bridge the flood tide runs for almost six hours, while the ebb tide endures for six hours and thirty minutes. The tides are much higher now than at other times in the history of the Thames. There can now be a difference of some 24 feet (7.3 m) between high and low tides, although the average rise in the area of London Bridge is between 15 and 22 feet (4.5 and 6.7 m). In the period of the Roman occupation, it was a little over 3 feet (0.9 m). The high tide, in other words, has risen greatly over a period of two thousand years.
The reason is simple. The south-east of England is sinking slowly into the water at the rate of approximately 12 inches (305 mm) per century. In 4000 BC the land beside the Thames was 46 feet (14 m) higher than it is now, and in 3000 BC it was some 31 feet (9.4 m) higher. When this is combined with the water issuing from the dissolution of the polar ice-caps, the tides moving up the lower reaches of the Thames are increasing at a rate of 2 feet (0.6 m) per century. That is why the recently erected Thames Barrier will not provide protection enough, and another barrier is being proposed.
The tide of course changes in relation to the alignment of earth, moon and sun. Every two weeks the high "spring" tides reach their maximum two days after a full moon, while the low "neap" tides occur at the time of the half-moon. The highest tides occur at the times of equinox; this is the period of maximum danger for those who live and work by the river. The spring tides of late autumn and early spring are also hazardous. It is no wonder that the earliest people by the Thames venerated and propitiated the river.
The general riverscape of the Thames is varied without being in any sense spectacular, the paraphernalia of life ancient and modern clustering around its banks. It is in large part now a domesticated river, having been tamed and controlled by many generations. It is in that sense a piece of artifice, with some of its landscape deliberately planned to blend with the course of the water. It would be possible to write the history of the Thames as a history of a work of art.
It is a work still in slow progress. The Thames has taken the same course for ten thousand years, after it had been nudged southward by the glaciation of the last ice age. The British and Roman earthworks by the Sinodun Hills still border the river, as they did two thousand years before. Given the destructive power of the moving waters, this is a remarkable fact. Its level has varied over the millennia--there is a sudden and unexpected rise at the time of the Anglo-Saxon settlement, for example--and the discovery of submerged forests testifies to incidents of overwhelming flood. Its appearance has of course also altered, having only recently taken the form of a relatively deep and narrow channel, but its persistence and identity through time are an aspect of its power.
Yet of course every stretch has its own character and atmosphere, and every zone has its own history. Out of oppositions comes energy, out of contrasts beauty. There is the overwhelming difference of water within it, varying from the pure freshwater of the source through the brackish zone of estuarial water to the salty water in proximity to the sea. Given the eddies of the current, in fact, there is rather more salt by the Essex shore than by the Kentish shore. There are manifest differences between the riverine landscapes of Lechlade and of Battersea, of Henley and of Gravesend; the upriver calm is in marked contrast to the turbulence of the long stretches known as River of London and then London River. After New Bridge the river becomes wider and deeper, in anticipation of its change.
The rural landscape itself changes from flat to wooded in rapid succession, and there is a great alteration in the nature of the river from the cultivated fields of Dorchester to the thick woods of Cliveden. From Godstow the river becomes a place of recreation, breezy and jaunty with the skiffs and the punts, the sports in Port Meadow and the picnic parties on the banks by Binsey. But then by some change of light it becomes dark green, surrounded by vegetation like a jungle river; and then the traveller begins to see the dwellings of Oxford, and the river changes again. Oxford is a pivotal point. From there you can look upward and consider the quiet source; or you can look downstream and contemplate the coming immensity of London.
In the reaches before Lechlade the water makes its way through isolated pastures; at Wapping and Rotherhithe the dwellings seem to drop into it, as if overwhelmed by numbers. The elements of rusticity and urbanity are nourished equally by the Thames. That is why parts of the river induce calm and forgetfulness, and others provoke anxiety and despair. It is the river of dreams, but it is also the river of suicide. It has been called liquid history because within itself it dissolves and carries all epochs and generations. They ebb and flow like water.
The River as Metaphor
The river runs through the language, and we speak of its influence in every conceivable context. It is employed to characterise life and death, time and destiny; it is used as a metaphor for continuity and dissolution, for intimacy and transitoriness, for art and history, for poetry itself. In The Principles of Psychology (1890) William James first coined the phrase "stream of consciousness" in which "every definite image of the mind is steeped . . . in the free water that flows around it." Thus "it flows" like the river itself. Yet the river is also a token of the unconscious, with its suggestion of depth and invisible life.
