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.

Examination of marks on a bone from Blombos Cave reveals that they were intentionally engraved and there is evidence of bone working techniques at the site. Engraved designs have also been identified on pieces of ochre from Blombos Cave, suggesting such engraving was a symbolic act with symbolic meaning.

The metal composition of bronze alloys has been routinely examined as a means of inferring the source of the ore. But bronze is recycled, and the quantity of some components, such as arsenic, is depleted every time the alloy is melted down. Since the Early Bronze Age of the British Isles was largely supplied from a single mine on Ross Island, Co. Kerry, tracking arsenic content shows the number of re-melts and this gives the object a biography and a social context. Applying this ingenious new procedure to their large database, the authors also winkle out other sources of supply and new insights about the technology involved.

This study considers exploitation of marine molluscs at Riparo Mochi (Italy) in cultural and ecological context. Five shell assemblages from this site represent the early Upper Palaeolithic (c. 36,000 BP) through Late Epigravettian (c. 9000 BP) periods. Taphonomic analysis reveals four kinds of shell debris: ornaments, food refuse, marine sponge inclusions, and land snails. While human foraging agendas at Riparo Mochi shifted over the five Palaeolithic phases, the kinds of marine shells favoured as ornaments remained nearly constant.

What are the advantages of equipping a wooden arrow with stone, rather than just using the sharpened wooden tip? Very few it seems. In a series of well-controlled experiments the authors show that stone arrow-heads achieve barely 10 per cent extra penetration over wood. They then raise some pertinent ideas about the other advantages, social and symbolic that may have driven hunters the world over to adopt the stone tip.

The ANTIQUITY prize-winning article in the last volume addressed writing, its varying nature and role in early states. Now that the decipherment of Maya writing is well advanced, we can know more of the records of kingship. From them we may discern the concepts and beliefs that defined the authority of these holy lords, as we seek the source of the power of rulers like ‘Sun-faced Snake Jaguar’.

For a century a notion of a prehistoric Mother Goddess has infused some perceptions of ancient Europe, whatever the realities of developing archaeological knowledge. With the reverent respect now being given to Marija Gimbutas, and her special vision of a perfect matriarchy in Old Europe, a daughter-goddess is now being made, bearer of a holy spirit in our own time, to be set alongside the wise mother of old.

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 propose a new model for the origins of humans and their ecological adaptation. The evolutionary stimulus lies not in the savannah but in broken, hilly rough country where the early hominins could hunt and hide. Such ‘roughness’, generated by tectonic and volcanic movement characterises not only the African rift valley but probably the whole route of early hominin dispersal.

The origin of pottery is among the most important questions in Old World archaeology. The author undertakes a critical review of radiocarbon dates associated with the earliest pottery-making and eliminates a number of them where the material or its context are unreliable. Using those that survive this process of ‘chronometric hygiene’, he proposes that food-containers made of burnt clay originated in East Asia in the Late Glacial, c. 13 700-13 300 BP, and appeared in three separate regions, in Japan, China and far eastern Russia, at about the same time.

The Middle Palaeolithic record of the Arabian Peninsula can provide crucial evidence for understanding human dispersal. The authors summarise the archaeological evidence and suggest some of the routes taken by the earliest humans coming out of Africa, including one implying the use of boats. Early populations adapted to a hospitable environment, but had later to adapt to the advance of the desert.

The authors use a social network analysis to map the changing patterns of obsidian supply among the Maya during the period of Classic to Postclassic transition. The quantity of obsidian received from different sources was calculated for 121 sites and the network analysis showed how the relative abundance of material from different sources shifted over time. A shift from inland to coastal supply routes appears to have contributed to the collapse of inland Maya urban centres. The methods employed clearly have a high potential to reveal changing economic networks in cases of major societal transitions elsewhere in the world.

The Jwalapuram Locality 9 rockshelter in southern India dates back to 35 000 years ago and it is emerging as one of the key sites for documenting human activity and behaviour in South Asia. The excavated assemblage includes a proliferation of lithic artefacts, beads, worked bone and fragments of a human cranium. The industry is microlithic in character, establishing Jwalapuram 9 as one of the oldest and most important sites of its kind in South Asia.

The date of the first settlement of the Americas remains a contentious subject. Previous claims for very early occupation at Pedra Furada in Brazil were not universally accepted (see Meltzer et al. 1994). New work at the rockshelter of Boqueirão da Pedra Furada and at the nearby open-air site of Vale da Pedra Furada have however produced new evidence for human occupation extending back more than 20 000 years. The argument is supported by a series of 14C and OSL dates, and by technical analysis of the stone tool assemblage. The authors conclude that the currently accepted narrative of human settlement in South America will have to be re-thought. The article is followed by a series of comments, rounded off by a reply from the authors.

It's an ill wind that blows nobody any good. The combination of land cleared of its rainforest for grazing and satellite survey have revealed a sophisticated pre-Columbian monument-building society in the upper Amazon Basin on the east side of the Andes. This hitherto unknown people constructed earthworks of precise geometric plan connected by straight orthogonal roads. Introducing us to this new civilisation, the authors show that the ‘geoglyph culture’ stretches over a region more than 250km across, and exploits both the floodplains and the uplands. They also suggest that we have so far seen no more than a tenth of it.

Language is a feature to distinguish the ‘human’ from the ‘animal’ that has seemed a more enduring diagnostic character than some. But how is the breath of words to be made visible in the stony traces of the Pleistocene?

The nature and date of the human colonization of Australia remains a key issue in prehistory at the world scale, for a sufficiently early presence there indicates either Homo sapiens sapiens arriving precociously in a place remote from a supposed African origin, or a greater competence in sea-crossing than has been expected of archaic humans. Stratigraphic integrity, the new science of luminescent dating and the recognition of worked stone and of rock-engraving are immediate issues in this report from far northwestern Australia.

At Jerf el Ahmar in northern Syria the authors have excavated a settlement where the occupants were harvesting and processing barley 1000 years in advance of its domestication. Rows of querns installed in square stone and daub buildings leave no doubt that this was a community dedicated to the systematic production of food from wild cereals. Given the plausible suggestion that barley was being cultivated, the site opens a window onto a long period of pre-domestic agriculture. Rye was also harvested, its chaff used to temper mud walls.
