Historical phenomena often have prehistoric precedents; with this paper we investigate the potential for archaeometallurgical analyses and networked data processing to elucidate the progenitors of the Southwest Silk Road in Mainland Southeast Asia and southern China. We present original microstructural, elemental and lead isotope data for 40 archaeological copper-base metal samples, mostly from the UNESCO-listed site of Halin, and lead isotope data for 24 geological copper-mineral samples, also from Myanmar. We combined these data with existing datasets (N = 98 total) and compared them to the 1000+ sample late prehistoric archaeometallurgical database available from Cambodia, Laos, Thailand, Vietnam and Yunnan. Lead isotope data, contextualized for alloy, find location and date, were interpreted manually for intra-site, inter-site and inter-regional consistency, which hint at significant multi-scalar connectivity from the late second millennium bc. To test this interpretation statistically, the archaeological lead isotope data were then processed using regionally adapted production-derived consistency parameters. Complex networks analysis using the Leiden community detection algorithm established groups of artefacts sharing lead isotopic consistency. Introducing the geographic component allowed for the identification of communities of sites with consistent assemblages. The four major communities were consistent with the manually interpreted exchange networks and suggest southern sections of the Southwest Silk Road were active in the late second millennium bc.

A small rural stopover along overland Maya and Aztec trade and travel routes was identified in surveys and excavations at adjacent settlements and shrines at Mensabak, Chiapas, Mexico. This collection of Late Postclassic to Spanish conquest-era (c. ad 1350–1650) Maya sites are similar in function to rural Old World and Andean caravan stopovers, such as caravanserai and way stations, where travellers and traders obtained supplies, trading partners, safety, solidarity through ritual and travel information along long-distance land routes. These sites are similar to trading ports and pilgrimage centres, but they are smaller, located in the countryside, not often managed by regional states, and have scaled-down economic exchange with fewer exotic trade items. Stopovers often include landscape and rock-art shrines for collective ritual among foreign travellers and local populations. While investigators have researched the anthropological importance of overland routes, caravans and trade centres, less attention has been given to stopover sites in the countryside. This article discusses the archaeological signatures and outlines the comparative social, economic and ritual implications of small rural stopover sites that united people on the road.

This paper describes the analysis of the Late Prehispanic rock-art site of Villavil 2 (Catamarca, Argentina). Despite its modest and inconspicuous nature, this is one of the few examples of rock-art sites known in the area to date. The relationship of the site with the surrounding landscape and the distribution of rock art throughout the site are analysed using a combination of GIS and 3D modelling. This analysis makes it possible to gain an understanding of the factors behind the location and distribution of rock art on different spatial scales. The interpretation presented here suggests that this rock art reproduces, on a modest local scale, patterns of production of Inka landscapes of control and dominion that have been recognized elsewhere, in sites with a much more obvious monumental scale. The internal organization of the site mimics, on a small scale, forms of interaction with the wider landscape that have been regionally observed, usually focusing on more conspicuous elements such as architecture.

Handaxes have a uniquely prominent role in the history of Palaeolithic archaeology, and their early study provides crucial information concerning the epistemology of the field. We have little conclusive evidence, however, of their investigation or societal value prior to the mid seventeenth century. Here we investigate the shape, colour and potential flake scarring on a handaxe-like stone object seen in the Melun Diptych, painted by the French fifteenth-century artist Jean Fouquet, and compare its features with artefacts from diverse (including French) Acheulean handaxe assemblages. Commissioned by a high-status individual, Étienne Chevalier, Fouquet's work (Étienne Chevalier with Saint Stephen) depicts an important religious context, while the handaxe-like object points to the stoning to death of an important Christian saint. Our results strongly support the interpretation that the painted stone object represents a flint Acheulean handaxe, likely sourced from northern France, where Fouquet lived. Identifying a fifteenth-century painting of a handaxe does not change what we know about Acheulean individuals, but it does push back the evidence for when handaxes became a prominent part of the ‘modern’ social and cultural world.

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.

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.

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.
