The Nebra disc is one of the most sensational European discoveries of the decade. It appears to carry symbols of the sun, moon and stars wrought in gold on a flat bronze disc just over a foot across (320mm). It is not only very strange, but, famously, appears to be winking, initially raising the suspicion that it may be a hoax. Scholars have, however, claimed it firmly for the Bronze Age, and the debate now moves to the matter of its meaning. Here the authors offer a subtle interpretation that sees it as the shamanistic device of a local warrior society.

Medieval ‘new towns’ seem to echo Roman towns in having a grid of streets associated with a fortress, and have often been credited with a standard plan applied by the hand of authority. Here the authors analyse the new towns founded by Edward I in Wales and find some highly significant variations. Rediscovering the original layouts by high precision survey and GIS mapping, they show that some towns, founded at the same time and on similar topography, had quite different layouts, while others, founded at long intervals, had plans that were almost identical. Documentation hints at the explanation: it was the architects, masons and ditch-diggers, not the king and aristocracy, who established and developed these blueprints of urban life.

The author argues for a significant social and cognitive transition between the Lower and Middle Palaeolithic in Europe. Between about 300 000 and 200 000 years ago, early Neanderthals developed stone working techniques which combined methods that were previously discrete, began to occupy high-relief terrain and to settle systematically the highly seasonal environments of central and eastern Europe – skill-sets here termed the ‘incorporation of difference’. These findings make us rethink the competence of pre-modern hominins and to review, in the author's words, ‘the boundaries we erect to police the uniqueness of humanity’.

The tooth of a tiger shark, perforated to make a pendant, was lost in New Ireland, New Guinea between 39500 and 28000 years ago. The author argues that this has to be the work of anatomically modern humans, and implies the use of symbolic language not only across the former continent of Sahul, but also Eurasia.

Prompted by a recent article by Jiang and Liu in Antiquity (80, 2006), Dorian Fuller and his co-authors return to the question of rice cultivation and consider some of the difficulties involved in identifying the transition from wild to domesticated rice. Using data from Eastern China, they propose that, at least for the Lower Yangtze region, the advent of rice domestication around 4000 BC was preceded by a phase of pre-domestication cultivation that began around 5000 BC. This rice, together with other subsistence foods like nuts, acorns and waterchestnuts, was gathered by sedentary hunter-gatherer-foragers. The implications for sedentism and the spread of agriculture as a long term process are discussed.

Armed with a number of powerful arguments, the authors invite us to face up to the evidence for violence in early Neolithic Europe. Linearbandkeramik (LBK) people first attacked the hunter-gatherers they encountered and then entered a period of increasingly violent warfare against each other, culminating in an intense struggle in the area of central and western Germany. The building of fortifications, physical mutilation and cannibalism, while no doubt enacted with ritual airs, nevertheless had their context and purpose in the slaughter of enemies.

In this important new review the author shows that neither trade nor migration can account for the distribution of Bell Beakers and the associated artefacts and burial practices in Europe. The materials were generally local and rooted in local know-how. However recent stable isotope results show small-scale population changes associated with the arrival of Beaker practice. The distribution of Bell Beakers could thus reflect the movement of marriage partners.

Cultural interactions in central Russia are famously complex, but of very wide significance. Within the social changes they imply are contained key matters for Europe and Asia: the introduction of Indo-Europeans and other languages, the horse and the chariot, and the transition towards nomadism. Of crucial importance to future research is a sturdy chronological framework and in this contribution the authors offer 40 new radiocarbon dates spanning the conventional Bronze Age in the southern Urals.

Urban communities on the medieval East African coast have been previously discussed in terms of ethnicity and migration. Here assemblages from coastal towns and from surface survey in the interior are used to paint a different picture of urban (Swahili) origins. The author shows that coast and interior shared a common culture, but that coastal sites grew into ‘stonetowns’ thanks to the social impact of imports: the material culture structured the society.

Archaeologists increasingly realise that prehistoric peoples had their own ideas about time. The concept of linear, measurable time emerged in learned Europe largely in the first millennium. Here the author tracks how, with the broadening of literacy in sixteenth-century Britain, dates start appearing on numerous items of popular culture. The dated objects in turn feed back into the way that people of all social levels began to see themselves and their place in history.

High in the mountains between Norway and Sweden, archaeological survey has brought to light a trail marked by standing stones at regular intervals and tall enough to show above the winter snows. In the absence of any cultural material, the erection of the stones was dated by the diameter of the lichen spreads upon them, and corroborated by a study of the documents and radiocarbon dates. The authors argue that this was not an indigenous trail but one constructed by a Norse chieftain probably around the ninth century AD to gain safe access to the fur-trading Sami.

How can we explain the variations and similarities of Palaeolithic art? Are we to suppose that European artists conformed to one great evolutionary sequence over 20 millennia? Or is the variation geographical, ideological or social? The author begins to address these big questions by deconstructing over 900 images of the horse, the animal most commonly depicted in European caves. He finds it possible to distinguish variations due to differences in live animals and due to differences in methods of representation – allowing the isolation of those few differences due to style. Applying this to a case study at Parpalló in Spain, he notes that the local sequence of horse images correlates with other cultural changes. Here is a method of great potential for revealing conservative and innovative trends.

The halberd – a famous weapon of prehistoric Europe – is thought by some to have had a symbolic rather than a functional purpose. To find out if, and how, it might have worked as a weapon, the author tested a replica on a number of sheep's heads, finding it highly effective in administering killer blows. Studies taking off from these experiments show that the halberd probably performed both in fighting and ritual, and in ritualised fighting, during its predominance in the Early Bronze Age.

In the latest of his periodic reviews of Celtic exhibitions in the pages of Antiquity (Megaw 1981; 1992; 1994) Vincent resumes the Grand Tour and evaluates a series of such events over the past decade.

We owe Professor Tikhonov warmest thanks for this brief history of academic archaeology at St Petersburg. As well as applauding the department's many achievements, readers of our Debate section will no doubt take note of a bleak period in its eventful history, one marked by a tendency to ‘substitute socio-political subjects for specialist courses’ and ‘the growing disparagement of highly skilled researchers and teachers’. If suitably candid authors can be found, we look forward to receiving similarly instructive intellectual biographies of archaeology departments and institutes from around the world.
