Ritual practices and their associated material paraphernalia played a key role in extending the reach and ideological impact of early states. The discovery of a leather bag containing snuffing tablets and traces of psychoactive substances at Cueva del Chileno in the southern Andes testifies to the adoption of Tiwanaku practices by emergent local elites. Tiwanaku control spread over the whole of the south-central Andes during the Middle Horizon (AD 500–1100) but by the end of the period it had begun to fragment into a series of smaller polities. The bag had been buried by an emergent local elite who chose at this time to relinquish the former Tiwanaku ritual practices that its contents represent.

Spectacular objects may carry powerful messages about cultural affinities and legitimation. Such is the case set out here for the Kargaly diadem, supposedly a headpiece, of gold and semi-precious stones buried in a pit on the southern edge of the steppe in the northern foothills of the Tianshan mountains some 2000 years ago. This was a period when the Han Empire of China was seeking to increase its hold over the western borderlands and it is in that context, and the fluctuating rivalries of local polities, that the Kargaly diadem is to be understood. Chinese iconography figures prominently on the diadem which may have been a diplomatic gift from the Han imperial court, but technological details suggest that it was produced within the western borderlands beyond China itself. The combination of Chinese and other elements testify to the fluidity of cultural interaction around the borders of the expanding Han Empire and the imitation and incorporation of symbols of power by contending local elites.

The island of Cyprus was a major producer of copper and stood at the heart of east Mediterranean trade networks during the Late Bronze Age. It may also have been the source of the Red Lustrous Wheelmade Ware that has been found in mortuary contexts in Egypt and the Levant, and in Hittite temple assemblages in Anatolia. Neutron Activation Analysis (NAA) has enabled the source area of this special ceramic to be located in a geologically highly localised and geochemically distinctive area of western Cyprus. This discovery offers a new perspective on the spatial organisation of Cypriot economies in the production and exchange of elite goods around the eastern Mediterranean at this time.

When and how did urban life in Roman Britain end? The excavations conducted by Philip Barker at Wroxeter from 1966–1990 produced evidence suggesting a post-Roman phase of urban activity that continued into the sixth or seventh century AD, up to 200 years beyond the traditionally accepted chronology. Careful re-examination of the evidence, however, throws doubt on these claims. More recent work on Late Roman Britain coupled with new discoveries in Wales and the west challenges the evidence for the post-Roman survival of Wroxeter as an urban centre and suggests that it may have been largely abandoned, along with other Roman towns, in the late fourth or early fifth century AD.

Biała Góra 3 is a small settlement founded in the late twelfth or early thirteenth century AD in the disputed Christian borderlands of Northern Europe. The incorporation of Pomerania into the Polish state in the tenth century was followed by a process of colonisation across the lower Vistula valley, which then stalled before resuming in the thirteenth century under the Teutonic Order. Biała Góra 3 is unusual in falling between the two expansionist phases and provides detailed insight into the ethnicity and economy of this borderland community. Pottery and metalwork show strong links with both Pomeranian and German colonists, and caches of bricks and roof tiles indicate durable buildings of the kind associated with the monastic and military orders. Evidence for the presence of merchants suggests Biała Góra 3 was one of many outposts in the commercial network that shadowed the Crusades.

The discovery of a grave of the late second millennium BC containing an extinct South American fox, Dusicyon avus, at Loma de los Muertos raises intriguing questions about the relationship between wild canids and humans. This sub-adult individual appears to have been buried in a human mortuary context in a comparable manner to adjacent human burials. It may have been kept as a pet and been considered part of the human social group. The ability of pets, especially canids, to leave the animal world and enter into a special relationship with people may be related to the cosmology of South American hunter-gatherers.

The growth of medieval cities in Northern Europe placed new demands on food supply, and led to the import of fish from increasingly distant fishing grounds. Quantitative analysis of cod remains from London provides revealing insight into the changing patterns of supply that can be related to known historical events and circumstances. In particular it identifies a marked increase in imported cod from the thirteenth century AD. That trend continued into the fifteenth and sixteenth centuries, after a short downturn, perhaps attributable to the impact of the Black Death, in the mid fourteenth century. The detailed pattern of fluctuating abundance illustrates the potential of archaeological information that is now available from the high-quality urban excavations conducted in London and similar centres during recent decades.

Sophisticated techniques of archaeological survey, including airborne imaging spectroscopy, electromagnetic induction and ground-penetrating radar, are opening up new horizons in the non-invasive exploration of archaeological sites. One location where they have yielded spectacular results is Carnuntum in Austria, on the south bank of the Danube, capital of the key Roman province of Pannonia. Excavations in the late nineteenth and twentieth centuries revealed many of the major elements of this extensive complex, including the legionary fortress and the civilian town or municipium. Excavation, however, is no longer the only way of recovering and recording the details of these buried structures. In 2011, a combination of non-invasive survey methods in the area to the south of the civilian town, where little was visible on the surface, led to the dramatic discovery of remains interpreted as a gladiatorial school, complete with individual cells for the gladiators and a circular training arena. The combination of techniques has led to the recording and visualisation of the buried remains in astonishing detail, and the impact of the discovery is made all the greater by the stunning reconstruction images that the project has generated.

The Illerup Aadal weapon sacrifice mirrors the material world of a Germanic army from c. AD 210. Apart from the personal equipment and the weaponry of more than 400 warriors, it comprises four horses. The present paper gives the first conclusive analysis of the skeletal remains of these animals, involving osteological investigation and strontium isotope analysis. The results shed new light on the character of the sacrificial ceremonies which unfolded in the aftermath of Iron Age battles; on the nature of cavalry and its significance in Iron Age warfare; and on the much debated question as to where the army of Illerup Aadal had originally come from.

Academic interest in the elaborate bead assemblages recovered from graves of the Western Zhou elite has grown in recent years. Beads and beaded ornaments have been seen as both markers of external contact and evidence of change in the Zhou ritual system. Recent study of these bead assemblages, however, indicates that they may also have reflected shifting political circumstances. The use of different bead materials and forms suggests a trend to centralised production and control of manufacture, particularly from the later tenth century BC. The authors correlate a move towards readily manufactured materials with evidence for widespread elite intermarriage, and consider a possible tension between production and the socio-political strategies of the Zhou court.

Raised field agriculture in the Basin of Mexico was a highly sustainable farming method that did not depend upon centralised political control. Study of the chinampa system around the Early and Middle Postclassic city of Xaltocan through a combination of remote sensing, GIS, targeted excavation and AMS dating has revealed an extensive area of raised fields that was abandoned when Xaltocan was conquered by an alliance of powerful neighbours during the fourteenth century AD. The rise and abandonment of the chinampa system were thus directly linked to the political economy of the city-state. The failure to revive the raised field systems in the following Aztec period can also be attributed to the impact of political, economic and ecological factors.

A bark shield now in the British Museum can be identified from documentary and pictorial evidence as one collected by Captain Cook during his first voyage to Australia in 1770. Such shields often had special value to their Australian Aboriginal owners and hence might have been exchanged over considerable distances. This particular shield is known to have been collected in Kamay Botany Bay but analysis of the bark of which it is made revealed it to be of red mangrove, a tropical species found today more than 500km distant on the New South Wales north coast. It hence bears valuable testimony to the long-distance exchange networks operating in eastern Australia in the period before the disruption caused by European colonisation.

The increasing availability of multi-dimensional remote-sensing data covering large geographical areas is generating a new wave of landscape-scale research that promises to be as revolutionary as the application of aerial photographic survey during the twentieth century. Data are becoming available to historic environment professionals at higher resolution, greater frequency of acquisition and lower cost than ever before. To take advantage of this explosion of data, however, a paradigm change is needed in the methods used routinely to evaluate aerial imagery and interpret archaeological evidence. Central to this is a fuller engagement with computer-aided methods of feature detection as a viable way to analyse airborne and satellite data. Embracing the new generation of vast datasets requires reassessment of established workflows and greater understanding of the different types of information that may be generated using computer-aided methods.

Recording devices formed of knotted cords, known as khipus, are a well-known feature of imperial administration among the Inka of Andean South America. The origins and antecedents of this recording system are, however, much less clearly documented. Important insights into that ancestry are offered by a group of eight khipus dating from the later part of the Middle Horizon period (AD 600–1000), probably used by the pre-Inka Wari culture of the central Andes. This article reports the AMS dating of four of these early khipus. A feature of the Middle Horizon khipus is the clustering of knots in groups of five, suggesting that they were produced by a people with a base five number system. Later, Inka khipus were organised instead around a decimal place-value system. Hence the Inka appear to have encountered the base five khipus among Wari descendant communities late in the Middle Horizon or early in the Late Intermediate period (AD 1000–1450), subsequently adapting them to a decimal system.

The temple of Angkor Wat in Cambodia is one of the most famous monuments in the world and is noted for its spectacular bas-relief friezes depicting ceremonial and religious scenes. Recent work reported here has identified an entirely new series of images consisting of paintings of boats, animals, deities and buildings. Difficult to see with the naked eye, these can be enhanced by digital photography and decorrelation stretch analysis, a technique recently used with great success in rock art studies. The paintings found at Angkor Wat seem to belong to a specific phase of the temple's history in the sixteenth century AD when it was converted from a Vishnavaite Hindu use to Theravada Buddhist.

The extensive cemetery at Hepu in southern China represents one of the best-preserved tomb complexes of the Han period. It contains many elaborate tombs with exotic luxury materials that testify to the status of Hepu as the home port of the maritime Silk Road. This trading network carried Chinese products (notably silks) by sea to kingdoms and communities of South and Southeast Asia, and was the southern counterpart to the more famous overland Silk Road through Central Asia. The materials found in the Hepu tombs demonstrate the range and geography of contacts, including semi-precious beads from India and ceramics from the Parthian empire. This far-flung trade network had major impacts both on southern China and on the other regions that it connected.

Monumental construction is commonly associated with the rise of complex societies and frequently supported the ceremonies and ideologies that were instrumental in the creation of the new social order. Recent fieldwork at Heketa in eastern Tongatapu recorded stone-built platforms for houses and seats, and a three-tiered tomb and trilithon. Tongan tradition and archaeology combine to show that these were the setting for new ceremonies instituted by the emergent Tu’i Tonga lineage in the fourteenth century AD as they laid the foundations of the early Tongan chiefdom. Key to their success were activities that emphasised the sacred origins of the living Tu’i Tonga, including the drinking of kava and the presentation of first fruits to the chiefs.

Almost a century and a half ago, Charles Darwin in The Descent of Man (1871: 141) highlighted the evolution of bipedalism as one of the key features of the human lineage, freeing the hands for carrying and for using and making tools. But how did it arise? The famous footprints from Laetoli in Tanzania show that hominin ancestors were walking upright by at least 3.65 million years ago. Recent work, however, suggests a much earlier origin for bipedalism, in a Miocene primate ancestor that was still predominantly tree-dwelling. Here Susannah Thorpe, Juliet McClymont and Robin Crompton set out the evidence for that hypothesis and reject the notion that the common ancestor of great apes and humans was a knuckle-walking terrestrial species, as are gorillas and chimpanzees today. The article is followed by a series of comments, rounded off by a reply from the authors.

How far are settlement patterns affected by imperial systems of administration and control? The prototype city state consisted perhaps only of the population centre and its surrounding hinterland, but large territorial states, and still more empires, required complex systems of government and defence. Historical sources tell of the Chinese imperial system of ‘commanderies’ or provinces, and ‘county seats’ or subordinate centres, but this may conceal a range of local variations and development histories that only detailed archaeological survey can reveal. In this study, devoted to the Northern Zone of the Han Empire close to its border with the troublesome Xiongnu, a four-fold hierarchy of walled settlements is presented which varies in its character, origins and development even within this single zone. Many of its special features can be attributed to the pressures and insecurities of the border setting, and are the direct result of Han imperial planning.

Bayesian analysis has come to be widely used in archaeological chronologies and has been a regular feature of recent articles in Antiquity. Its application to linguistic prehistory, however, has proved controversial, in particular on the issue of Indo-European origins. Dating and mapping language distributions back into prehistory has an inevitable fascination, but has remained fraught with difficulty. This review of recent studies highlights the potential of increasingly sophisticated Bayesian phylogenetic models, while also identifying areas of concern, and ways in which the models might be refined to address them. Notwithstanding these remaining limitations, in the Indo-European case the results from Bayesian phylogenetics continue to reinforce the argument for an Anatolian rather than a Steppe origin.
