A system of abandoned ridge/earthwork features covers a large swathe of the Shaṭṭ al-ᶜArab floodplain in southern Iraq, standing as testament to a period of agricultural expansion in the past. Until now, the chronology of these features has been surmised from limited textual evidence that relates their construction to slave labour during the early Islamic period associated with the ‘Zanj rebellion’. This article presents the first absolute dates from this ridge system, demonstrating that these features were in use for a substantially longer period than previously assumed and, as such, they represent an important piece of Iraqi landscape heritage.

Written accounts suggest there were major changes in agricultural practices in Anatolia as the region switched between Roman, Byzantine, Arab and Turkic control, yet archaeological evidence of these changes is offered only on a site-by-site basis. This article presents the first synthesis of archaeobotanical, palynological and zooarchaeological evidence for changes in plant and animal husbandry in Anatolia through the first and second millennia AD. Available data indicate a minimal role of climate change in agricultural shifts but offer evidence for substantial changes towards short-term-return agricultural strategies in response to declining personal security, changing patterns of military provisioning and distinct taxation regimes.

An increase in knowledge is usually beneficial but can also highlight misapprehensions of existing data. Such is the case for the Pictish-Norse transition in Northern Scotland in the later first millennium AD. New radiocarbon dates from the key ‘transitional’ settlement of Buckquoy, Orkney, reveal that traits previously published as indicative of incoming Norse influence pre-date the start of the Viking Age, suggesting a greater level of endogenous change than hitherto has been appreciated. Here, the authors underscore the need for a re-evaluation of other settlement sequences across the later Pictish and early Norse periods, reopening many questions about the transition.

Enclosed rectangular farmsteads from the Hallstatt period in Central Europe are often cast as the seats of high-status farmers, whose land and social standing could be inherited and consolidated. Excavations at Landshut-Hascherkeller in Bavaria reveal the developmental trajectory of one such site through the stratigraphic disentanglement of its numerous ditches. Here, the authors argue that the coalescence of two rectangular farmsteads into a larger settlement complex at Hascherkeller reflects the union of neighbouring families and the resultant massing of status. The article situates this process in a segmented social system that counterpoints the typified Hallstatt hierarchy, suggesting that two social structures coexisted in the Hallstatt culture.

Kinship can be difficult to discern in the archaeological record, but the study of ancient DNA offers a useful window into one form of kinship: biological relatedness. Here, the authors explore possible kin connections at the post-Roman site of Worth Matravers in south-west England. They find that, while clusters of genetically related individuals are apparent, the inclusion of unrelated individuals in double or triple burials demonstrates an element of social kinship in burial location. Some individuals also carried genetic signatures of continental ancestry, with one young male revealing recent West African ancestry, highlighting the diverse heritage of early medieval Britain.

Representations of the human body are ubiquitous in cultures across the world. Beyond the aesthetic, figurines transmit deeper meanings that were readily decodable by their intended audience and may still offer sociocultural insights despite the loss of this coding through time. The discovery of a rare tableau of ‘Bolinas’-type clay figurines dating to 410–380 BC at San Isidro, El Salvador, now permits the theoretical reconstruction of a less stratified Preclassic society in south-east Mesoamerica and the exploration of its spheres of interaction, which may have stretched along the coast from Guatemala to Costa Rica.

Salt works along the Yucatan coasts of Mexico and Belize provide a record of salt production for inland trade during the height of Late Classic Maya civilisation (AD 550–800). At the Paynes Creek Salt Works in Belize, production focused on the creation of salt cakes by boiling brine in pots supported over fires in dedicated salt kitchens. Underwater excavations at the Early Classic (AD 250–550) site of Jay-yi Nah now indicate there was a longer and evolving tradition of salt making in the area, one that initially employed large, incurved bowls to meet local or down-the-line trade needs before inland demand for salt soared.

The Late Iron Age (fourth–first centuries BC) district of Carpetania in the Central Iberian Peninsula is traditionally cast as a marginal territory, where cultural development is primarily attributed to acculturation, diffusionism and imitation. Here, the authors critically re-evaluate published evidence from the site of El Cerrón, Illescas, focusing on a decorated terracotta relief with a ‘Mediterraneanising’ style to argue that the local elite was not a passive actor in history. Instead, the community at El Cerrón actively engaged in the cultural dynamics that shaped not only the Iberian Peninsula but also the wider Mediterranean basin during this crucial period.

Archaeological evidence suggests that the transition to food-producing economies in the Western Valleys of northern Chile led to a decline in foraging in highland areas around AD 650, yet colonial records from the sixteenth and eighteenth centuries attest to the continued existence of foraging groups. Taking the Camarones River Basin as a test case, this study identifies small-scale settlements and hunting installations in upland areas using remote-sensing data. In considering these new data alongside ethnohistorical accounts, the author proposes that foraging endured into the late colonial era, possibly coexisting with herder and agropastoral communities and precipitating tethered settlement patterns.

As with the peopling of the Pacific Islands, the monumental ritual architecture of East Polynesia is presumed to have spread from West Polynesia. By re-examining the wealth of absolute dates available from ritual contexts across these diverse islands, the authors challenge this generalisation in Polynesian ideological materialisation, identifying three phases of development. They argue that initial west-to-east migration spread the concept of ritual spaces marked by stone uprights c. AD 1000–1300, then the formalisation of monuments diffused in the opposite direction c. AD 1300–1600, before megastructures emerged from localised hierarchisation, perhaps earliest on Rapa Nui c. AD 1350–1500.

The nature and extent of interactions between the distant regions and cultures of Mesoamerica remain open to much debate. Close economic and political ties developed between Teotihuacan and the lowland Maya during the Early Classic period (AD 250–550), yet the relationship between these cultures continues to perplex scholars. This article presents an elaborately painted altar from an elite residential group at the lowland Maya centre of Tikal, Guatemala. Dating to the fifth century AD, the altar is unique in its display of Teotihuacan architectural and artistic forms, adding to evidence not only for cultural influence during this period, but also for an active Teotihuacan presence at Tikal.

There are no known written records pertaining to the origins of the enigmatic bronze ‘Lion’ that stands atop one of the two large columns of the Piazzetta in St Mark’s Square, Venice (Italy). Representing the Venetian Winged Lion, a powerful symbol of statehood, the sculpture was installed during a time of political uncertainty in medieval Mediterranean Europe, yet its features do not reflect local artistic conventions. Here, the authors argue that stylistic parallels are found in Tang Dynasty China (AD 618–907); employing lead isotope analysis, they further show that the figure was cast with copper isotopically consistent with ore from the Lower Yangzi River basin.

From the perspective of the present, the economic development of preceding periods can seem linear and inevitable, guided into being by those who benefitted most from increasing commercialisation. Yet this majoritarian narrative belies the importance of the individual and the everyday, of adaptation and creativity. Here, the author explores the potential of a minoritarian approach to entrepreneurship, in understanding medieval economic development. In tracing pottery-exchange networks as a representation of commercial development, they argue that the entrepreneurial actions of institutions and potters generate insights into economic development that challenge linear narratives, framing it as a patchwork of sociomaterial relations.

In Viking archaeology, the study of miniature figurines cast in silver and bronze provides a platform for debates on ritual and mythology, yet much of this discourse focuses on their appearance. Here, the authors use microwear and Reflective Transformation Imaging to survey the physical evidence of complex relational dynamics between 10 anthropomorphic artefacts from Viking Age Sweden and the human bodies they connected with. Through such analyses, and the abandonment of a priori assumptions regarding their purpose and symbolism, these figures can be seen as more than just components of an imposed category, and their varied, transmutable engagements with the world can be explored more freely.

At Ollantaytambo, in the Cusco region of Peru, the Inka (c. AD 1400–1532) built an elaborate anthropogenic landscape to facilitate intensive agriculture. After the 1532 Spanish invasion of the region, this landscape was reshaped by the introduction of new plants and animals, colonial land-management practices and demographic transformations. Here, the author employs botanical data from a derelict Inka-era reservoir to evaluate the timing and character of colonial transformations to the local agroecology. These transformations, they argue, tended towards agricultural deintensification, but this process did not begin until decades after the Spanish invasion.

The tradition of beating bark to produce cloth probably emerged in South China before spreading to Island Southeast Asia with the Austronesian cultural expansion (5000–3500 BP). Type IV barkcloth beaters found on the island of Sulawesi mark a technological leap from mainland examples and the discovery of 16 such beaters at Buttu Batu pushes the local adoption of this type back to c. 2111–1933 BP. Combining archaeological examples with extensive ethnographic research, the authors document an early-twentieth-century diversification in the patterning of grooves on type IV beaters, revealing a unique innovation aimed at improving barkcloth quality in response to increasing competition.

Historical texts suggest that medieval Christianity condemned the consumption of horsemeat (hippophagy) yet also indicate that this practice persisted. Here, the authors review the contribution of horse to food refuse at 198 settlements across medieval Hungary, highlighting variability in food practices through time and space. Examination of these zooarchaeological assemblages indicates that hippophagy continued after the general conversion to Christianity in the eleventh century but substantially declined following the Mongol invasion (AD 1241–1242) and disappeared by the mid-sixteenth-century Ottoman occupation. Diachronic and geographic trends in this practice reveal ambiguity in food customs, reflecting complex (social, religious and ethnic) local identities.

Radiocarbon dates can offer important corollaries for historic events and processes, including territorial expansion and consolidation in early empires. Eighteen new radiocarbon dates from test excavations at Ak'awillay, near the Inca imperial capital of Cuzco, reveal new perspectives on interactions between the Incas and Xaquixaguana Valley groups. Rather than persisting as a regional centre, Ak'awillay declined well before early Inca expansion, remaining largely unoccupied until after an extensive empire had been established. This new chronology adds nuance to the growing understanding of local group interactions and how they contributed to Inca state development and imperial expansion.

The sacralisation of mountains played an important role in the expansion of the Inca Empire into the south-central Andes during the mid-second millennium AD. Here, the authors compare archaeological material from sacralised mountains in north-western Argentina, highlighting not just the shared attributes of high-altitude sites but also the diversity of ways in which Inca dominion over the mountains could be materialised. Focusing on Mount Inca Viejo, in the Argentine province of Salta, the authors further explore the characterisation of sacred mountains and the significance of mining and mineral acquisition as a motivator for Inca expansion.

The nature and extent of the Tiwanaku state expansion in the Andes during the second half of the first millennium AD continues to be debated. Here, the authors report on the recent discovery of an archaeological complex 215km south-east of Tiwanaku, where a large, modular building with an integrated, sunken courtyard strongly resembles a Tiwanaku terraced platform temple and demonstrates substantial state investment. Constructed, the authors argue, to directly control inter-regional traffic and trade between the highlands and the eastern valleys of Cochabamba, the complex represents a gateway node that effectively materialised the power and influence of the Tiwanaku state.
