The interpretations offered here do not lend themselves to exactness, and it is all too easy to quote results to a nonsensical degree of accuracy that might suggest otherwise. There are writers who publish declinations and directions that by implication are accurate to a thousandth of a degree, but who have not even taken astronomical altitude into account, although it would have displaced their findings by angles of the order of a degree, twice the diameter of the Sun. There have been archaeologists who have considered that they have done their duty by the points of the compass if they have marked them on their plans to within five or six degrees. Those who repeat the threadbare story of Mrs Maud Cunnington, who is said to have made some of her measurements with an umbrella, should compare her azimuths with their own. A good umbrella is far better fitted to the accurate measurement of length than is a pocket compass to the accurate measurement of direction.
The many different sorts of monument to be considered were first and foremost religious centres, or at least focal points of religion, built by people in whose spiritual lives the stars, Sun, and Moon played an important role, perhaps even a central role. There are limits to what an insight into past observational practice can reveal about prehistoric religion, its symbolism and ritual, but one should not be unduly apologetic about its genuinely scientific nature. The activities reconstructed here were rule-directed, scientific in a very real sense, and their implications for human history, intellectual and practical, are anything but trivial. Here, for instance, we can dimly perceive the beginnings of mathematical astronomy, the oldest of the exact sciences, not to mention the roots of a geometry of proportion—which was destined to have an important place in ancient Greek philosophy and science. As a window into the beliefs of the past, this all surely deserves at least as much attention as a showcase of flint scrapers.

My debts are numerous. I was very fortunate to have Bill Swainson cast an editor’s eagle eye over my script. To the late A. G. Drachmann I owe the idea of self-denial in the matter of footnotes. I have weakened only occasionally—but then at some length—when adding asides that might have stood in the way of the main argument. Appendices and Bibliography are included at the end. (Those unaware of the distinction between dates BC and bc, for example, might consult Appendix 1. A few readers might want the basic astronomy in Appendix 2.) I should never have turned in the direction of Stonehenge in the first place without the encouragement of Francis Maddison thirty years ago, and his broad view of archaeology has certainly coloured my own. Richard North passed a critical eye over my Scandinavian asides. Above all I owe a debt to an entire profession that is not really mine, and especially to Tjalling Waterbolk for his expert comment, on the continental material in particular. The book’s dedication, however, can only be to my wife Marion for her unstinting support. And to her patience, not even Chaucer’s Clerk could have done justice.

A few typographical corrections to the first printing have been made here, together with some minor adjustments to the star maps of Figs. 4 and 210. That the corrections called for were not more numerous I owe largely to the care of my editor Toby Mundy. My indebtedness to him has accumulated steadily since he first took the book in hand.

… the Discovery whereof I doe here attempt (for want of written Record) to work-out and restore after a kind of Algebraical method, by comparing those that I have seen one with another; and reducing them to a kind of Aequation: so (being but an ill Orator my selfe) to make the Stones give Evidence for themselves.

MOST of the achievements recorded in this book were those of people who lived between three and six thousand years ago—a relatively short period by comparison with the quarter of a million years that Britain has been inhabited. During that long earlier period, following the arrival of the first hunters in these northern latitudes, there had been gradual but massive fluctuations in climate, and long glacial periods during which it would have been necessary to retreat southwards. Much of what is known about the general pattern of existence of early peoples derives from evidence as to their diet, for example from middens, and hunters are in this regard by their very lifestyle elusive. The few hunter-gatherers who were cave dwellers—and especially those from temperate regions in the same period—tell us that there were other dimensions to their lives than subsistence alone, for they have left us carved and modelled figurines in stone and clay, including those notorious ‘Venuses’ who look as though they were meant as wives for Michelin man. Even from a time as early as the Leptolithic period (say 35,000 to 10,000 BC) there have been found in France not only many specialized tools and weapons, but spectacular cave art. Among surviving artefacts are bones scratched in ways suggesting that some sort of counting was taking place, and on the basis of the grouping of incisions into sets of around thirty, claims have been made that some of the counting was of the days of the Moon.
It is from the Leptolithic period that the first clear indication of ritualized burial in Britain has been found, that of the ‘Red Lady’ (or was it a young man?) found in a cave at Paviland on the Gower Peninsula in Wales. The body had been covered in red ochre—presumably to give it a semblance of life in death—and had been dressed in ornaments of ivory and shell. Radiocarbon dating puts this at well over twenty thousand years ago, when there was still a land bridge to the continent of Europe.1 Both shells and ochre have been found with similar Middle Palaeolithic burials in France and southeastern Europe, and indeed red ochre was to be used in the same way throughout Europe for many millennia thereafter.
The last of the long periods of glaciation lasted for about sixty thousand years, and drew to a close about eleven thousand years ago, even though there are signs of intelligent activity with stone implements from an earlier date. As the climate changed, and temperatures rose to levels more or less those of the present, northern Europe
