Ancient Mesoamericans are generally thought to have imagined the universe stacked in vertical layers, not unlike the cosmic layers of Dante's Comedy. Dismantling this model, our authors show it to be based upon a post-conquest European-Aztec hybrid. This penetrating critique tracks the history of the hybrid cosmos from its first appearance through its resilient repetition until today.

With its forts, swords, halberds and daggers the Argaric people of south-east Spain has long been seen as a warrior society. The authors dismantle this model, showing that defences around settlements and weapons and knives in tombs have quite different social roles. An analysis of skeletons showed that while these Bronze Age people might have been periodically clubbing each other on the head, they were not doing a lot of lethal stabbing.

In medieval Korea certain burials were sealed in concrete resulting in the exceptional preservation of organic materials, including, in this case, written documents. As well as studying changes in rank and ideology, archaeologists who investigate tombs are often moved to wonder about the character of the deceased, the thoughts of the mourners and their hopes and fears on the passing of a person dear to them. In this extraordinary burial from Korea, we hear these voices directly.

With the help of a modern mason, the authors have discovered a series of scarcely visible markings on well-known limestone statues from southern Spain dating back to the fifth century BC. Unrelated to letters or religious symbols, their best point of comparison seems to lie with the kind of signature used by masons to denote a craftsman or workshop. One can certainly forgive any sculptor an expression of pride in the elegant and complex carvings of the Iberian culture.

Glass – one of the most prestigious materials of the early Islamic empire – was traded not only as vessels and bangles but as raw glass blocks. One of its raw materials, plant-ash, was also traded. This means that tracking the production of this precious commodity is especially challenging. The authors show that while chemical composition can relate to vessel type, it is a combination of chemical compositions with strontium and neodymium isotope ratios that is most likely to lead to (a geological) provenance for its manufacture. The materials used by the glassmakers were local sand and plant ashes. Reported here is the first application of the method to the glass made at the primary glass making centre of al-Raqqa, Syria in an environmental context.

Guided by modern miners of the region the authors track down pre-Inca mining sites in the Southern Nasca Region of Peru. In the hinterlands away from both modern and ancient roads they find a surprising number of small sites serving the pre-Inca industry, principally in the Nasca period. Drawing analogies from modern practice they are able to distinguish the ancient sites dedicated to exploration, extraction or production.

Highly mobile people must have sheltered in structures of some kind; but these are notoriously difficult to find. The author uses nineteenth-century photographs of an occupied Apache settlement to show how such shelters may have been made, comparing them with their archaeological remains in the present day. This suggests a ‘signature’ for the temporary shelters used by mobile groups in any period.

Are the imposing, decorated copper-alloy shields of Bronze Age Europe symbolic objects or functioning weapons? The author undertakes new analysis and experiments to conclude that whether bronze, leather or wood, all shields had a range of purpose in which the ceremonial and homicidal could rarely be completely isolated.

A single coin discovered in a field at Chalgrove, Oxfordshire, UK, has proved to have an exceptional significance in the world of Roman numismatics. It features a third-century emperor, Domitianus, unknown apart from a find of 1900 from a vineyard in Cléons previously described as ‘doubtful’. The dies used to strike the two coins match, leaving little doubt that Domitianus was a real person, although of somewhat fleeting dominion over the Gallic Empire – for a brief period in AD 271.

It is probable that ‘The Farm Beneath the Sand’ will come to stand for a revolution in archaeological investigation. The authors show that a core of soil from an open field can provide a narrative of grazing animals, human occupation and their departure, just using DNA and AMS dating. In this case the conventional archaeological remains were nearby, and the sequence obtained by the old methods of digging and faunal analysis correlated well with the story from the core of ancient ‘dirt’ DNA. The potential for mapping the human, animal and plant experience of the planet is stupendous.

A decorated pair of trousers excavated from a well-preserved tomb in the Tarim Basin proved to have a highly informative life history, teased out by the authors – with archaeological, historical and art historical dexterity. Probably created under Greek influence in a Bactrian palace, the textile started life in the third/second century BC as an ornamental wall hanging, showing a centaur blowing a war-trumpet and a nearly life-size warrior of the steppe with his spear. The palace was raided by nomads, one of whom worked a piece of the tapestry into a pair of trousers. They brought no great luck to the wearer who ended his days in a massacre by the Xiongnu, probably in the first century BC. The biography of this garment gives a vivid glimpse of the dynamic life of Central Asia at the end of the first millennium.

As noted by Geoffrey Chamberlain, the two baby girls found in Tutankhamen's tomb were probably his stillborn heirs. More controversially he suggested that they were twins, although one appeared to be larger than the other. Here new research on estimating the age of a fetus is shown to support the twin hypothesis, while recent work on Twin-Twin Transfusion Syndrome explains why they could be such different sizes.

The authors show how sites in upland Hawai‘i may be dated using uranium series radiogenic measurements on coral. The sites lie in a quarry, inland and at high altitude, with little carboniferous material around, and radiocarbon dating is anyway problematic here for the first millennium. Freshly broken coral had been transported to these sites, remote from the sea – no doubt for ritual purposes. Giving a date in the fifteenth century with an error range of only five years, the method promises to be valuable for the early history of the Pacific.

The authors disentangle the fascinating tale of the investigations in Kent's Cavern, iconic site for the acceptance of early man. The drawings they have discovered in the archives of the Geological Society are the only ones known from the earliest excavations and they are published here for the first time. As this paper shows, it takes intellectual courage to be an archaeologist. Whatever the enormity of his challenge to contemporary religion, I like to think that MacEnery would have been fairly supported by Antiquity's reviewing system. But perhaps our doctrinal challenges are lesser ones.…

Stable isotopes in skeletons indicate changes in diet, and a sample of humans from Classical Thebes showed an unexpected increase in nitrogen values – usually associated with increased access to protein. But from what and how? After considering the possible sources of meat, milk and manure, the authors highlight the contribution of freshwater fish, and find support in Aristophanes – where the citizens are heard clamouring for the eels of Lake Kopais.

This deconstruction of how Apulian red-figure pottery came to be termed Tarentine has implications for archaeological methodology far beyond the Mediterranean. The author shows how the assumptions of great authorities, themselves rooted in a colonial world, led to a highly resistant model of core and periphery for pottery production that may have no basis in fact. It is a fine example of the process that has left us with so many unsuitable and immovable names for material from Samian to Gothic.

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.

You didn't need to be an archaeologist in 2008 to know that things were happening at Stonehenge. For years controversial plans to improve the Stonehenge environs (costed at £600m) had dominated media and much academic debate, but in November 2007 the British government announced that it couldn't afford them (Pitts 2008a). The plans were dropped (much cheaper changes are now being implemented to make Stonehenge look nice for the 2012 Olympics: English Heritage 2008). There are new broadcasts and press stories featuring the stones every year, but 2008 was different. As road protests diminished, real archaeologists took the stage.

What better way to understand how to make a handaxe or cleaver than getting into an Acheulean quarry and doing it yourself. The authors experimented at Isampur Quarry in India, finding that handaxes were best produced by reducing a slab to shape, while cleavers were best made by striking large flakes. There was a good correspondence with the ancient implements, and the authors deduced that Acheulean hominins were learning and transmitting standardised manufacturing methods to each other.

We are grateful to Chris Evans for convening and introducing this imaginative archaeological tribute to the work of Charles Darwin, 150 years after the publication of his On the origin of species – the inspiration for an evolutionary concept of history in so many fields. June 2009 is also the 150th anniversary of a yet more momentous event in the history of archaeology, the endorsement of the antiquity of human tool-making by observations in the Somme gravels. Clive Gamble and Robert Kruszynski reconstruct the occasion and publish the famous axe for the first time. Chris Evans returns to present us with the bitter-sweet spectacle of the Darwin family as excavators and Tim Murray rediscovers a suite of pictures made for John Lubbock which show how prehistoric life was envisaged in polite society at the time. Lastly we are grateful to Colin Renfrew for his own reflections on the anniversary.
