Here is a major research project that is peopling the Indian Ocean with prehistoric seafarers exchanging native crops and stock between Africa and India. Not the least exciting part of the work is the authors' contention that the prime movers of this maritime adventure were not the great empires but a multitude of small-scale entrepreneurs.

Through intensive archaeological investigation of temples in Hawai'i, the authors reveal a sequence of religious strategies for creating and maintaining authority that has application to prehistoric sequences everywhere. Expressed in the orientation and layout of the temples and their place in the landscape, these strategies develop in four stages over the course of a few hundred years, from the fifteenth to nineteenth century AD, from local shrines associated with agriculture to the development of a centralising priesthood serving the larger political economy.

Tadmekka, a town at the southern edge of the Sahara desert, has produced good evidence for making gold coins in the ninth–tenth century AD, the first concrete proof of coinage in pre-colonial West Africa. These were produced by melting gold dust or nuggets in ceramic moulds, similar to those used for the first pellet-like coinage of the European Iron Age. The authors suggest these coins were not political statements, but were probably blank and intended to facilitate the busy early Islamic caravan trade to destinations north, south or east. On arrival at the Mediterranean coast, these blank pieces would have been melted down or converted into inscribed coins by the local authorities.

The Staffordshire (Ogley Hay) hoard was found on the 5–10 July 2009 by Mr Terry Herbert while metal-detecting on arable land at a site in south Staffordshire in the English Midlands (Figure 1).Mr Herbert contacted Duncan Slarke, the Portable Antiquities Scheme's Finds Liaison Officer for Staffordshire and the West Midlands, who visited the finder at his home and prepared an initial list of 244 bags of finds. These were then taken to Birmingham Museum and HM Coroner was informed. Duncan Slarke also contacted the relevant archaeological authorities including English Heritage, the Staffordshire Historic Environment Record, the Potteries Museum, Stoke-on-Trent, Birmingham Museum & Art Gallery and the Portable Antiquities & Treasure Department at the British Museum. A meeting was held in Birmingham on 21 July at which it was agreed that the controlled recovery of the remaining objects of the hoard and an archaeological investigation of the findspot was a priority. It was also agreed that one of the Portable Antiquities Scheme's National Advisors, Dr Kevin Leahy, should compile a hand-list of finds in preparation for the Coroner's Inquest.

Commercial excavators often find that their way back to the past runs through relatively recent structures. What should we do with them? Intellectually sensitive modern excavators, like our authors, are beginning to convince us that these recent constructions not only matter in themselves, but may have interesting links to what lies beneath. Here they introduce us to the foundations of an early telescope, a monument that takes its context both from the much-investigated lands of West Cambridge, and the more abstract landscape of early science. Forcing archaeology to ask fresh questions and make ambitious connections is only proper in a place heavy with the aroma of investigative scholarship.

An important group of spindle whorls found at Tha Kae in Thailand carries traces suggesting the use of iron spindles, and includes an unusual type of whorl shaped like a door knob. The author explores the implied contacts reaching into south China, but is also able to add a probable link with India in the early first millennium AD, well in advance of the better known Dvaravati period (sixth–thirteenth centuries AD).

Five wooden sculptures from the pre-contact Caribbean, long held in museum collections, are here dated and given a context for the first time. The examples studied were made from dense Guaiacum wood, carved, polished and inlaid with shell fastened with resin. Dating the heartwood, sapwood and resins takes key examples of ‘Classic’ Taíno art back to the tenth century AD, and suggests that some objects were treasured and refurbished over centuries. The authors discuss the symbolic properties of the wood and the long-lived biographies of some iconic sculptures.

The hoard presents us with a startling number of unfamiliar images from the Anglo-Saxon past, not least in the new icon of treasure that it presents. As the descriptions of treasure and gift-giving in Beowulf so vividly remind us, the gaining of treasure, and its corollary, gift-giving, were major preoccupations for Anglo-Saxons and their northern European contemporaries, whether Clovis, showering the crowds in Tours with gold solidi when he was created consul in 508, Oswiu attempting to buy off Penda before the Battle of Winwæd with what Bede (HE III.24; Colgrave & Mynors 1969: 288–91) described as an incalculable and incredible store of royal treasures or the huge Danegelds extorted by Vikings in the tenth and early eleventh century. But until July 2009, the picture presented by the archaeological evidence for Anglo-Saxon treasure could hardly have been more different: the material remains of treasure with which we are familiar come overwhelmingly from high-status burials, or as individual gold finds without context, most of them the result of relatively recent metal-detecting activity. Only one seventh-century Anglo-Saxon gold hoard exists, from Crondall in Hampshire, dated to c. 640; but that is essentially a coin hoard, the only non-numismatic items two small clasps which must have fastened the purse or satchel containing the coins.

This is certainly a strange business: on the one hand, the thrill of discovery, the glory of gold, the flattery of the media and the purring of officialdom; on the other, the agonised frustrations of academics whose job it is to make sense of everything brought to light on this island. An editor is supposed to remain neutral, but in this case there is no contest. Antiquity champions research — so while we are happy to welcome the arrival of a mass of shiny things, we are bound to lament the loss of an opportunity to understand what they mean. Then there is the paradox of the English system: the treasure hunters are applauded and rewarded, but the archaeologists are seemingly obliged to lurk in the shadows, anxious not to spoil the party. Does it have to be like this?

A multi-disciplinary study of settlement in north-east Greenland found that life in this High Arctic zone was actually favoured by the climate brought in by the Little Ice Age (fifteenth–nineteenth century). Extensive ice cover meant high mobility, and the rare polynyas — small patches of permanently open coastal water — provided destinations, like oases, where huge numbers of migrating marine mammals and birds congregated. One such place was Walrus Island on Sirius Water, a veritable processing plant for walrus, where every spring Thule people stocked up meat supplies that would get the rest of the region through the winter. It was a further drop in the temperature in the mid nineteenth century that led to the region being abandoned.

In case readers are wondering whether this paper is written tongue in cheek — or with tongue sticking out — it is worth recalling that modern archaeology includes recent periods in its remit, and uses recent materiality to help understand more ancient times as well as a critique on modernity itself. Here the authors find graffiti left by a notorious group of popular musicians and probe it for social meaning as earnestly as students of cave art. Their archaeological study finds an underlying driver that is part political, part personal and therefore also part (anti-)heritage.

In the spring of 1970, tired of the chilly Philadelphia winters where I was studying archaeology at the University of Pennsylvania, I arranged to spend a semester at the University of Hawai'i. There I enrolled in Professor Wilhelm G. Solheim II's course inthe prehistory of Southeast Asia. Bill Solheim — a colorful character if ever there was one, with his handle-bar mustache and endless anecdotes — was just then stirring up the sleepy field of Southeast Asian archaeology and prehistory. Together with his graduate students Chet Gorman and Don Bayard, Bill was making all kinds of startling claims about thecourse of cultural evolution in what most scholars had taken to be a secondary backwater: evidence for strikingly early plant domestication from Spirit Cave, precocious advances in bronze metallurgy at Non Nok Tah, and similar claims. At the time, Peter Bellwood, then based at the University of Auckland, was still focused on research among the islands of eastern Polynesia. But Peter saw the exciting developments coming out of Southeast Asia and soon decamped to The Australian National University in Canberra. Out of this new base he began his long and fruitful career of fieldwork in island Southeast Asia, and as the preeminent synthesiser of the region's prehistory.

The author shows how pollen and oribatid mites recovered from the small lake of Marcacocha provide a detailed proxy record of agro-pastoralism over the last 4200 years in the central Andes. The introduction of highland maize and weeding practices 2700 years ago corresponds with major settlement development, as well as evidence for large herds of llamas not only facilitating trade but supplying abundant fertilizer and fuel in the form of excrement. Prolonged droughts and pre-Colombian epidemics probably influenced many of the social changes observed.

In this neat investigation of a harbour site, the authors show how much can be learnt by site survey — and by surface plotting and remote mapping in particular. Here the excavations are used to pilot the geophysics, rather than the other way round, and ground-penetrating radar is employed to show not just where features are, but their sequence and their current vulnerability. This exemplary project demonstrates how, in modern approaches to fieldwork, sites are to be studied rather than excavated, comprehended rather than stripped.

The authors investigate the origins of the earliest script of the Cherokees, using inscriptions in the Red Bird River Shelter. Their analysis suggests that the engravings in the cave show the experimental creation of a syllabary (alphabet of signs). This in turn offers support for the historical notion that this writing system was not an ancestral practice preserved through missionaries, but an invention of the early nineteenth century; one that should be credited to the Native American pioneer scholar, Sequoyah.

Few events of European prehistory are more important than the transition from ancient to modern humans around 40 000 years ago, a period that unfortunately lies near the limit of radiocarbon dating. This paper shows that as many as 70 per cent of the oldest radiocarbon dates in the literature may be too young, due to contamination by modern carbon. Future dates can be made more secure — and previous dates revised — using more refined methods of pre-treatment described here.

Children are often under-represented in excavated populations due to the poor survival of their bones. Using a group of medieval burials from Serbia, our researchers examine the differential survival of children and of different parts of the body within the same terrain, and rightly urge us to take these factors into consideration before attempting demographic, ritual or social interpretations.

By an interesting coincidence the village of Gilund in Rajasthan, north-west India was host to an important Chalcolithic settlement of the early third millennium BC and to some of the last indigenous potters still working in the twenty-first century AD. The author shows how her study of the prehistoric potters was enhanced by what she learnt from their modern successors, pointing out that she was only just in time. These potters will be the last to practice and in this respect ethnoarchaeology is itself under threat.

Identifying animals to species from relict proteins is a powerful new archaeological tool. Here the authors apply the method to answer questions relating to the Salish of west coast North America. Did they weave their blankets out of dog hair? The proteomic analysis shows that they did, interweaving it with goat, and that the woolly dog was increasingly superseded by sheep in the later nineteenth century.

Two conflicting theories put the introduction of bronze into Southeast Asia 1000 years apart, one (before China) at 2000 BC, the other at 1000 BC. Both were drawn from radiocarbon dates, the first of pottery, the second of bone. The authors cut the Gordian Knot by showing the earlier dates to be unreliable — but their study has implications way beyond Thailand. The direct dating of pottery, it seems, is full of pitfalls…
