СКАЧАТЬ than the average for such early Homo sapiens, and radiocarbon dates have shown he was alive around twenty-six thousand years ago – again, pretty well contemporary with Lagar Velho.

      The molecular biologist Brian Sykes, writing in the definitive report, describes how DNA extracted from the bones can be related to the commonest ancestry extant in Europe. This strongly suggests that the current population of Britain arrived in these islands in the Palaeolithic, and did not spread here seven thousand years ago with the arrival of Neolithic farmers from farther afield. As we will see later, it was most likely the concept of farming that reached us, rather than a wholesale migration of farmers.

      I’ll describe the details of the Red ‘Lady’s’ burial in a moment, but first I must say a few words about radiocarbon dating, which will become a regular feature of our story from now onwards.

      Radiocarbon dating was invented by Willard F. Libby, a chemist at Chicago University, in 1949.²⁹ The idea behind the technique is straightforward enough. Libby was researching into cosmic radiation – the process whereby the earth’s outer atmosphere is constantly bombarded by sub-atomic particles. This process produces radioactive carbon, known as carbon-14. Carbon-14 is unstable and is constantly breaking down, but at a known and uniform rate: a gram of carbon-14 will be half broken down after 5730 years, three-quarters broken down in twice that time (11,460 years), and so on. Libby’s breakthrough was to link this process to living things, and thence to time itself.

      Carbon-14 is present in the earth’s atmosphere – in the air we all breathe – in the form of the gas carbon dioxide. Plants take in the gas through their leaves, and plant-eating animals eat the leaves – and carnivores, in turn, eat them. So all plants and animals absorb carbon-14 while they are alive. As soon as they die, they immediately stop taking it in, and the carbon-14 that has accumulated in their bodies – in their bones, their wood or whatever – starts to break down through the normal processes of radioactive decay. So by measuring the amounts of carbon-14 in a bone, or piece of charcoal, fragment of cloth or peat, it is possible to estimate its age.

      But there are problems. First of all, cosmic radiation has not been at a uniform rate, as Libby at first believed. Sunspots and solar flares are known to cause sudden upsurges of radiation. Nuclear testing has also filled the atmosphere with unwanted and unquantifiable radiation. If these problems weren’t enough, the quantities of radiation being measured in the radiocarbon laboratories around the world are truly minute, especially in older samples, such as those from Paviland Cave. Efforts have been made to quantify the way in which radiocarbon dates deviate from true dates, using ancient wood samples that can be precisely dated to a given year AD or BC. This process is known as calibration, and is now widely accepted in archaeology (I’ve tried consistently to use calibrated radiocarbon dates in this book). All this uncertainty means that radiocarbon dates are usually expressed in the form of a range of years – say 1700 to 2000 BC, rather than a single central spot-date of 1850 BC.

      A by-product of radiocarbon dating are the figures known as the ‘stable isotope values’ of carbon and nitrogen. These provide very useful information on the general nature of an individual’s diet when the bone was being formed. It would appear that fish and seafood formed a major part of the Red ‘Lady’s’ diet. Today the sea is close by Goat’s Hole Cave, but in the Upper Palaeolithic it was about a hundred kilometres away. Of course, fish could have been caught in rivers closer by, but such a very ‘fishy’ diet surely suggests regular access to the sea – and with it a way of life that must have involved a great deal of travel. The contrast with Boxgrove, which was closer to the sea, but where there was no evidence for fish-eating, is remarkable; but then, so too is the huge time-span (roughly 480,000 years) that separates these two Palaeolithic sites – it’s easy to forget that the Palaeolithic takes up about 98 per cent of British prehistory.

      There are remarkable aspects to the Paviland burial which illustrate some of the far-reaching changes that were in the process of transforming humanity. That may sound grandiloquent, but the Upper Palaeolithic was the first period in which many of the defining characteristics of modern civilisation become apparent. Put another way, without the social and intellectual developments of the period, what was subsequently to be known as civilisation would have been impossible. It is difficult to overstate the importance of the achievements made by the people of the Upper Palaeolithic period. We may not always be aware of it, but we owe them an enormous amount.

      There is far more to Paviland than just the famous burial. The cave floor also produced numerous flint implements and the by-products of their manufacture, together with charcoal and ash, all of which were found in contexts that must predate the burial. Radiocarbon dates suggest that this earlier occupation preceded the Red ‘Lady’ by three thousand years (i.e. about twenty-nine thousand years ago), and there is evidence that the cave was intermittently occupied both before and after that date, as well as after the Red ‘Lady’ burial. This extended use would indicate that the Goat’s Hole Cave was well known to people at the time.

      The Red ‘Lady’ burial was accompanied by a mammoth ivory bracelet and a perforated periwinkle pendant, numerous seashells and some fifty broken ivory rods. Marker stones were placed at the head and foot of the grave. The staining, which most people regard as being derived from heavily stained clothes or wrapping, still colours the two ornaments and the bones, but there is a colour difference between the bones of the arms and chest and the hips and legs – which perhaps suggests that the young man was buried in a two-piece garment of some sort. The feet were only lightly stained, which would indicate that he wore shoes. The ochre, a natural product, was obtained locally. The body was headless, and it’s quite possible that it was deliberately buried in this way – other headless burials are known from this period – but the removal of the head could also have taken place later: perhaps it was carried away by the sea, which is known to have broken into the cave. The archaeological term for disturbance of this sort, which takes place after a deposit, such as a burial, has been placed in the ground, is ‘post-depositional’. It can sometimes take a great deal of skill to distinguish between an action that took place when a body was placed in the ground and a subsequent, post-depositional, effect. It’s something I always have in the back of my mind when I’m excavating.

      Paviland Cave also revealed three remarkable bone spatulae. They are small things, roughly six inches (fifteen centimetres) long, and are beautifully shaped, with unusual curves and bulges that don’t seem to make immediate practical sense. As well as the spatulae, there were a number of worked pieces of mammoth ivory, including a well-known perforated pendant that was thought to have formed part of the burial assemblage. Radiocarbon now shows that these objects were slightly later than the Red ‘Lady’ burial, and indicates that the cave was repeatedly used between about twenty-five and twenty-one thousand years ago.

      To sum up, there was a main phase of settlement in the cave around twenty-nine thousand years ago, with intermittent occupation both before and after. Then came the burial, at twenty-six thousand, and later use of the cave between twenty-five and twenty-one thousand years ago. It’s no wonder that Paviland Cave is the richest Upper Palaeolithic site in Britain – but does this pattern of use and reuse tell us anything more about the site? I believe that the Goat’s Hole Cave was a special place of some sort. If archaeologists have a fault it is to describe everything they find as special, unusual or remarkable. That’s because it is to them personally, who have spent weeks, months or years slaving away at whatever it might be. But is it to the world in general? In the case of Paviland it most certainly is, for the following reasons.

      Paviland Cave lies at the extreme northern edge of the Early Upper Palaeolithic world, and it was used remarkably late in the sequence, when the climate was getting very chilly. Those unique bone spatulae and the episode of mammoth-ivory working happened at a time when the climate was rapidly deteriorating and evidence for settlement elsewhere in Britain was virtually unknown. If we also bear in mind that nearly all well-preserved occupied cave sites have extensive living areas outside the cave itself, and СКАЧАТЬ
