We have documented more than 200 relative values of gold and silver across almost 3000 years (2500 bce–400 ce) to establish value benchmarks for essentially pure metal. Our aim is to improve understanding of ancient economies by enabling regional and temporal comparisons of these relative values. First, we establish silver as an early, reliable benchmark for valuing gold of varying purity before implementation of parting. Whilst purity accounted for two to threefold variation in the value of gold, we conclude that availability was more influential. Access to Nubian gold until about 1100 bce seems an important influence on gold-silver value ratios in Egypt and the Near East, which increased significantly following loss of this source. This investigation yields a suite of relative values for essentially pure gold and silver, subdivided by regions and intervals from 2500 bce–400 ce. These will enable future comparisons of precious metal-denominated costs of labour and commodities, including with today.

Domestic architecture is increasingly revisited as a source of data about wealth inequality in the distant past via the Gini coefficient, a statistical tool often used in economics to compare income inequality. Many areas—including South America, Africa, South Asia and Oceania—remain under-sampled, making it difficult to develop a more complete picture of ancient political economies. In this paper we present a first look at this measure in the Hawaiian Islands. These data show that during the period prior to contact with Europeans inequality was extremely high, most similar to autocratic archaic states. We also found geographic patterning that may ultimately be linked to dryland (non-irrigated) farming. On islands reliant on dryland farming (Mau‘i, Hawai‘i), we find distinctively less inequality than elsewhere, or larger house sizes. We hypothesize these may have been innovations in how wealth was made visible to create and maintain cooperation in places where more labour would have been required to grow surplus. More research is necessary to test this hypothesis, investigate alternative interpretations, and to put these findings in larger regional context within Polynesia.

The ever-growing body of research on trans-Eurasian exchange during the third–first millennium bce continues to improve understanding of mechanisms that facilitated the movement of objects, materials, ideas, and even people. However, whether bronze mirrors in Central Asia and China represent the exchange of technological knowledge or movement of the objects themselves remains unresolved, as researchers require extensive knowledge of huge quantities of data generated during the Soviet Central Asia campaigns of the mid twentieth century. The often confusing, impenetrable excavation reports, combined with required knowledge of Chinese, Russian and English, have caused much confusion about dates and contexts. This article presents and compares data published in Russian and Chinese reports. By clarifying the chronology for mirrors in Central Asia and China, we challenge simplistic theories of object diffusion and spread that persist in studies of trans-Eurasian exchange. We argue that the early second-millennium bce appearance of mirrors in western and northwestern China resulted from different exchange mechanisms specific to each local socio-cultural context. This demonstrates not only the complexity of interactions at the group and individual levels, but also how these factors can be integrated with data-driven analyses to explore the role they played in large-scale Bronze Age exchange networks.

Past and present cultures perceive their natural landscape as an integral and vital component of their complex worlds, while particular landscape features and associated monuments built in selected locales become sacred and revered through stories, legends and rituals embedded in mundane and ceremonial events. The hyper-arid Har Tzuriaz area in the southern Negev, Israel, offers a case study of culture-geographic continuities over a chronologically cumulative archaeological sequence. The large set of well-preserved structures located adjacent to water sources, a massive escarpment and a major desert crossroads includes campsites, cult sites, rock-art sites, cairn fields and one desert kite (a large game trap). Cultural continuities and change can be traced from the sixth millennium bce through recent times, reflecting a dynamic system of meanings and interpretations of both the natural and the built landscape within one particular sacred area in the desert. These phenomena are exemplified in archaeological analyses of an open-air shrine, burial cairns, an isolated desert kite and a precise engraving of that kite dated 5000 years later, all in the general context of a dense concentration of surveyed sites.

This paper aims to contribute to the current debate about Posthumanism in archaeology, arguing for the potential that Posthumanism can have for the study of rock art. Through a case study in San Luis Potosí, Mexico, this work seeks to explore a posthuman approach to rock art as vibrant and relational assemblages, through affects as relational agencies and non-human personhood and ritual landscape as theoretical tools, articulated with aspects from indigenous ontologies explored from archaeological, ethnographic and documentary information. It is proposed that this approach can help interpret hunter-gatherer rock art created between 1000 and 1500 ce in the northern region of Mexico. Through this exercise it is considered that Mexican archaeology of rock art can embrace posthumanism for a more complex and comprehensive understanding of the painted memory of hunter-gatherers from this part of the world.

The influence of pareidolia has often been anecdotally observed in examples of Upper Palaeolithic cave art, where topographic features of cave walls were incorporated into images. As part of a wider investigation into the visual psychology of the earliest known art, we explored three hypotheses relating to pareidolia in cases of Late Upper Palaeolithic art in Las Monedas and La Pasiega Caves (Cantabria, Spain). Deploying current research methods from visual psychology, our results support the notion that topography of cave walls played a strong role in the placement of figurative images—indicative of pareidolia influencing art making—although played a lesser role in determining whether the resulting images were relatively simple or complex. Our results also suggested that lighting conditions played little or no role in determining the form or placement of images, contrary to what has been previously assumed. We hypothesize that three ways of artist–cave interaction (‘conversations’) were at work in our sample caves and suggest a developmental scheme for these. We propose that these ‘conversations’ with caves and their surfaces may have broader implications for how we conceive of the emergence and development of art in the Palaeolithic.

Archaeology is centrally concerned with the tension between material remains in the present and a reconstructed past. This tension is captured by the concept of a trace, namely a contemporary phenomenon that references the past through some sort of epistemic intervention. Traces are deceptively complex in terms of both their epistemology and their ontology and hence worthy of detailed exploration. In particular, archaeological traces not only concern the past per se but also possess a latent quality of as yet unrealized signification. This gives archaeological traces a future orientation that is rarely considered in discussions of archaeological epistemology.

Archaeological materials from the Mediterranean world in Southeast Asia are scarce and their social context and cultural implications are rarely considered, while objects in Mediterranean style are often misinterpreted or overlooked. Concomitant to the increasing implementation of laboratory analysis, the range of new evidence, especially coming from recently excavated sites in Thailand and Myanmar, along with the reinterpretation of earlier data now brings the potential to compare different regions, and to discuss possible variations in terms both of the diversity and density of Roman materials. This study includes Mediterranean imports produced between the last centuries bce and first centuries ce, as well as Asia-produced inspired objects that integrate Mediterranean elements to varying degrees, combining new data and re-analysed materials. The paper not only contributes to building the sequence of cultural exchanges, but also interprets in cultural terms the varying Mediterranean elements present.
