What happened at the sites of prehistoric burial mounds after they were erected? In the southern highlands of Brazil and Argentina the pre-Hispanic mounds of the twelfth-thirteenth centuries AD are surrounded by large circular enclosures with avenues leading to their centre. The authors discovered that the banks of the surrounding enclosure were built up over several generations of time, accompanied by a succession of ovens. Ethnohistoric observations of more recent peoples in the same region suggested an explanation: the cremation of a chief was followed by periodic feasts at his mound, where meat was steamed and maize beer prepared at the edge of the gathering.

This paper addresses the cause of the Viking episode in the approved Viking manner – head-on, reviewing and dismissing technical, environmental, demographic, economic, political and ideological prime movers. The author develops the theory that a bulge of young males in Scandinavia set out to get treasure to underpin their chances of marriage and a separate domicile.

The Iron Age in north-eastern Thailand is marked by the appearance of multivallate ‘moated sites’ some of them up to 50ha in extent. Current evidence for their date and function shows them to be contemporary with other developments – expansion into new agricultural land, increases of ranking in burial and the arrival of regional pottery industries. In interpreting the reasons for these changes, the author draws on analogies from the Bronze/Iron transition in Britain, where forts are also seen as instruments of socio-economic change.

The archaeological sites of Iraq, precious for their bearing on human history, became especially vulnerable to looters during two wars. Much of the looting evidence has been anecdotal up to now, but here satellite imagery has been employed to show which sites were looted and when. Sites of all sizes from late Uruk to early Islamic were targeted for their high value artefacts, particularly just before and after the 2003 invasion. The author comments that the ‘total area looted … was many times greater than all the archaeological investigations ever conducted in southern Iraq and must have yielded tablets, coins, cylinder seals, statues, terracottas, bronzes and other objects in the hundreds of thousands’.

Deposits of human and animal bodies in a monumental Akkadian building at Tell Brak (ancient Nagar) superficially suggest random killing and disposal. But here the authors produce evidence that these represent the deliberate sacrifice of valued creatures. Among the human remains were those argued to represent a specialist acrobat, while the donkey remains reflect the association of the building with the breeding of the much-debated onager-donkey hybrid that preceded the horse.

At Antiquity's invitation the author offers this account of recent research and current objectives at the famous ancient Mesoamerican city of Teotihuacan. After a century of investigation, archaeologists are beginning to see something of the composition and preoccupations of one of America's first urban societies, and how it began, flourished and ended.

Using a new approach that combines high-quality coring with AMS dating, the authors are mapping the start of the Neolithic in Aegean Thrace – a missing link in the arrival of agriculture in Europe. The method also revealed the edge of the marine transgression dating to some 2900 years ago, implying that sites located near the coast in early Neolithic times have in all likelihood been lost to the sea.

When a monument is excavated it removes a piece of cultural property from the landscape. So modern thinking in field archaeology rightly includes the maintenance of monumentality in its initial design. Better still if that value is enhanced. Reconstructing their excavated tumulus in Albania, the authors found they could leave the monument in place and give it added value from the new knowledge of its relevance to local people, not to mention the revival of a dying craft: the making of mud-brick.

Techniques for identifying organic residues in pottery have been refined over the years by Professor Evershed and his colleagues. Here they address the problem of radiocarbon dating these residues by accelerator mass spectrometry (AMS) which in turn dates the use of the pot. Fatty acids from carcass and dairy products cooked in the pot were isolated from early Neolithic carinated bowls found at the Sweet Track, Somerset Levels, England, and then dated by AMS. The results were very consistent and gave an excellent match to the dendrochronological date of the trackway. The method has wide potential for the precise dating of pottery use on sites.

‘Any study of Great Zimbabwe has to rely a great deal on re-examining and re-assessing the work of early investigators, the men who removed all the most important finds from the ruins and stripped them of so much of their deposits’ (Garlake 1973: 14). The authors have here done us a great service in reviewing the surviving archaeological evidence from this world famous site. They challenge the structuralist interpretation – in which different parts of the site were allocated to kings, priests, wives or to circumcision rituals – and use the architectural, stratigraphic and artefactual evidence accumulated over the years to present a new sequence. The early enclosures on the hill, the Great Enclosure and the valley enclosures now appear as the work of successive rulers, each founding a new residence and power centre in accord with Shona practice.

A research team at Akrotiri, Thera, here examine the Bronze Age frescoes and show that the artists were making use of templates of well known geometric curves. Some of the spirals, hyperbolae and ellipses which all feature in the repertoire do not occur in nature and must have their origin in some still unknown human science or aesthetic.

Maya Blue is a colour that is more than a pigment; it had roles in status, ritual and performance, being daubed onto pots and people before sacrifice. Here researchers use experimental and historical evidence to discover how it was made, including direct scientific analysis of Maya Blue on a pot thrown into the sacred well at Chichén Itzá. The results indicate that the formation of the colour was actually part of the ritual.

The discovery of the extraordinary Hirschlanden figure was reported in this journal in 1964. Since then the statue has featured in numerous discussions of Iron Age art and society, to the extent that it has become one of the iconic images of the European Iron Age. It has become almost taken for granted that the Hirschlanden figure is an ‘intensely masculine’ warrior statue representing the heroised dead. However, certain aspects of the figure suggest a rather deeper, more ambiguous symbolism. The authors use their up-to-date critique to raise questions about the eclectic character of Iron Age spirituality.

On Tongatapu the central place of the rising kingdom of Tonga developed in the fourteenth and fifteenth centuries AD. Marked out as a monumental area with a rock-cut water-carrying ditch, it soon developed as the site of a sequence of megalithic tombs, in parallel with the documented expansion of the maritime chiefdom. The results of investigations into these structures were achieved with minimum intervention and disturbance on the ground, since the place remains sacred and in use.

Beatrice de Cardi has been a figure in British archaeological life for much longer than most of us can remember. Less well-known outside Asia are her achievements as an explorer of the archaeology of the countries of the lower Persian Gulf. Here she offers a brief mémoire for us, penned at the age of 93. It is a story of pottery, peoples and vast tracts of ancient lands, then little known.

Forty years after they were originally acquired for intelligence purposes, declassified US photographs from the KH-7 GAMBIT photo reconnaissance satellite programme, together with contemporary declassified intelligence reports, are being used to shed light on Cold War sites in the former Soviet Union. The method should have a great future for understanding the changes to the landscape in Europe over the last 60 years. The material impact of the Cold War was no less fundamental than other wars hotter in nature.

Thanks to a number of well-stratified sequences, the authors can offer a new history of clay image-making in West Africa. From the first known human occupation in the second millennium BC, the shaped clay figurines remain remarkably conservative, suggesting their use as offerings, toys or in games or some role rooted in domestic everyday life. Only in the late first millennium BC and in one area (Walasa) does a more formal art emerge in north-eastern Nigeria, a development contemporary with the famous Nok culture further south.

Archaeological investigation in India begins conventionally with the interest of Europeans. But India's own historical texts reveal examples of indigenous, curiosity-driven fieldwork as early as the sixteenth century. Describing the systematic search for lost sacred images and sites in places associated with Krishna's earthly pastimes, the author makes a spirited case for regarding this activity as real archaeology, comparing it with today's heritage projects.

CORONA satellite imagery, preserving an account of the earth's surface from 40 years ago, is a most important archaeological survey tool and we have often sung its praises. Here the authors use new procedures to extend the competence and revelations of CORONA even further. Stereo pairs derived from images taken from fore and aft of the satellite give three dimensional images of landscapes and even individual sites. Techniques of modelling and rectification restore the sites to their original shape without recourse to survey on the ground – in many cases no longer possible since the sites have been buried, inundated or erased. The ingenuity shown here indicates that results from CORONA are only going to get better.

The authors raise spatial analysis to a new level of sophistication – and insight – in proposing a mathematical model of ‘imperfect optimisation’ to describe maritime networks. This model encodes, metaphorically, the notion of gravitational attraction between objects in space. The space studied here is the southern Aegean in the Middle Bronze Age, and the objects are the 34 main sites we know about. The ‘gravitation’ in this case is a balance of social forces, expressed by networks with settlements of particular sizes and links of particular strengths. The model can be tweaked by giving different relative importance to the cultivation of local resources or to trade, and to show what happens when a member of the network suddenly disappears.
