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.

CORONA satellite photography taken in the 1960s continues to reveal buried ancient landscapes and sequences of landscapes – some of them no longer visible. In this new survey of the Mughan Steppe in north-western Iran, the authors map a ‘signature landscape’ belonging to Sasanian irrigators, and discover that the traces of the nomadic peoples that succeeded them also show up on CORONA – in the form of scoops for animal shelters. The remains of these highly significant pastoralists have been virtually obliterated since the CORONA surveys by a new wave of irrigation farming. Such archaeological evaluation of a landscape has grave implications for the heritage of grassland nomads and the appreciation of their impact on history.

The Ottoman fighting bow emerged in Europe from a long eastern tradition of using high velocity projectiles to hunt and fight on horseback. The author compares its performance (favourably) with the longbow and explains how the tactics employed with this singular artefact accounted for Ottoman success in battle.

Lands in south-central Chile, long thought to have been marginal until the Spanish conquest, are here shown to have been developing complex societies between at least AD 1000 and 1500. Part of the motor was provided by coastland cultivation on raised platforms, here identified and surveyed for the first time. The authors date the field systems and suggest that they were introduced by farmers from the north seeking wetlands in the face of increasing aridity in the central Andes and southern Amazon.

From examining the remains of charred cowpeas from rock shelters in Central Ghana, the authors throw light on the subsistence strategies of the Kintampo people of the second millennium BCE. Perhaps driven southwards from the Sahel by aridification, the Kintampo operated as both foragers and farmers, cultivating selected plants of the West African tropics, notably cowpea, pearl millet and oil palm.

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.

Satellite surveys in Syria have made use of imagery recorded some 30 years apart. By comparing the earlier pictures (Corona) with the later (Ikonos), sites captured on the former can be accurately located by the latter. The comparison also reveals the stark implications for archaeology as large parts of west Asian landscape change from a state of ‘benign neglect’ to active redevelopment. Based on their experience in the Homs survey, the authors have important advice to offer in the design and costing of surveys using satellite imagery.

The authors show that the Jomon clay figurines made by hunter-gatherers use imagery that emphasises a narrow waist and full hips, showing that a female construct was part of the symbolism of these possibly shamanistic objects. In creating these figurines, prehistoric people were no doubt turning a recognition of health and fertility into more cultural icons. Admirers of the female form will be interested to learn that preference for the fuller, curvaceous ‘hourglass’ shape ‘has probably been the norm over much of human evolution’.

Ever since Wheeler's triumphant discovery of Roman pottery at Arikamedu in the 1940s, it has been appreciated that the east coast of India was in reach of the Roman Empire. Tracking down the finds of Roman pottery on the Indian sub-continent reported since then, the author discovered that many of the supposed Roman amphorae were actually ‘torpedo jars’ from Mesopotamia. Here the areas of influence of these two great imports, probably of wine, are mapped for the first time.

The Gravettian is considered one of the first pan-European cultures of the Upper Palaeolithic, spreading from Portugal to Russia between 28-20000 years BP and characterised by backed blades and points. The Noaillian is a local variant in southern Europe (Northern Spain, Southern France and Italy). In France Noaillian is supposedly evolving into the Rayssian which is replaced later by recent Gravettian. By reconsidering the formation processes of some key stratigraphic sequences, the author demonstrates that the Rayssian is an idiosyncratic culture that does not have abrupt-backed bladelets, and that runs chronologically in parallel with the others. A case study, based on new work at the site of La Picardie (Indre-et-Loire), suggests that we should expect to define different contemporary regional groups during this long period.

The ancient Sri Lankan city of Anuradhapura is currently the subject of one of the world's largest and most intensive archaeological research projects. Having traced its growth from an Iron Age village to a medieval city, the research team now moves to the task of modelling the surrounding landscape. Three seasons of fieldwork have located numerous sites of which the most prominent in the urban period are monasteries. Here is a clue about how the early urban hinterland was managed which has implications well beyond Sri Lanka.

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.

This paper explores the influence of merchants operating out of Germany in medieval Turku by comparing the evidence of documentary reports and the quantity and distribution of imported pottery. The documents make it clear that German merchants were present in the town and generally keep themselves aloof from the local citizens. But the pottery tells a different and more subtle story of interaction and involvement in which all parties are potential drivers. The author calls into question the ethnic and exploitative models for a Hansa culture, preferring a post-colonial interpretation that allows us to see the formation of cultures that are hybrid and local in context.

How useful is archaeology to historians? Do they use it in their work? If so how? Catherine Hills considers a number of mighty histories of early medieval Europe that have recently appeared and examines how far the extremely productive archaeology of the last two decades has affected them – or failed to.

Investigations in a catacomb revealed an early mass grave, in which the bodies were bound tightly with plaster and textile in a type of mummification. Over 100 individuals, mostly young adults, including women, were stacked in rows apparently following a communal fatal incident, perhaps an epidemic. The presence of traces of gold, silver and probably amber with many of the bodies, and their burial in an imperial property suggests a group of some status being interred in the early years of the catacomb, at the end of the second century AD or beginning of the third.

As well as being modes of supplying metal, cross-shaped copper ingots in Zimbabwe are shown to be emblems of currency and status. The author dates them to the first half of the second millennium AD and connects the appearance of ingots to increased social stratification.

Here is a new application of infra-red photography with a digital camera to record rock art. The need to make full and accurate records of the images, without touching (and thus degrading) the rock, requires a method of remote mapping. Trials with digital IR reported here are very promising and especially useful for painted rock art.
