The abundance of obsidian at the Pottery Neolithic Wadi Rabah culture (7600/500–6800 cal. bp) settlement of Hagoshrim IV in northern Israel, the rich repertoire of stamp seals, and imported chlorite vessels at the site, as well as the presence of skilled obsidian knappers, indicate intensive trade. Reviewing the archaeological data, we propose that the obsidian discovered at Hagoshrim IV and at other Wadi Rabah sites of the southern Levant reflects one of the earliest forms of a kin-based direct trade. Kin-based direct trade partnerships revolve around the migration of family members from the source area of the goods to areas in which the goods are highly valued to form trading communities and act as agents to receive them. We further propose that Hagoshrim acted as a possible trading community, interacting with the Wadi Rabah settlements of northern Israel and that the transition in the source of the obsidian from mainly central Anatolian sources (in the Pre-Pottery Neolithic period) to mainly Eastern Anatolian sources (in the Pottery Neolithic period) is connected with changes occurring at the source areas of the obsidian, possibly the rise of the Halaf cultural complex in the northern Levant c. 7900 cal. bp. All these indicate that the Wadi Rabah culture was well integrated in the expanding interaction sphere of the Middle and Late Halafian.

In at least 400 European caves such as Lascaux, Chauvet and Altamira, Upper Palaeolithic Homo sapiens groups drew, painted and engraved non-figurative signs from at least ~42,000 bp and figurative images (notably animals) from at least 37,000 bp. Since their discovery ~150 years ago, the purpose or meaning of European Upper Palaeolithic non-figurative signs has eluded researchers. Despite this, specialists assume that they were notational in some way. Using a database of images spanning the European Upper Palaeolithic, we suggest how three of the most frequently occurring signs—the line <|>, the dot <•>, and the —functioned as units of communication. We demonstrate that when found in close association with images of animals the line <|> and dot <•> constitute numbers denoting months, and form constituent parts of a local phenological/meteorological calendar beginning in spring and recording time from this point in lunar months. We also demonstrate that the sign, one of the most frequently occurring signs in Palaeolithic non-figurative art, has the meaning . The position of the within a sequence of marks denotes month of parturition, an ordinal representation of number in contrast to the cardinal representation used in tallies. Our data indicate that the purpose of this system of associating animals with calendar information was to record and convey seasonal behavioural information about specific prey taxa in the geographical regions of concern. We suggest a specific way in which the pairing of numbers with animal subjects constituted a complete unit of meaning—a notational system combined with its subject—that provides us with a specific insight into what one set of notational marks means. It gives us our first specific reading of European Upper Palaeolithic communication, the first known writing in the history of Homo sapiens.

This paper unpacks the cognitive processes potentially involved in comprehending funerary ‘models’ from ancient Egypt. These objects comprise small scenes, usually made of wood, which have been found in burial chambers of pharaonic-era tombs. After considering the fittingness of the term ‘model’, the paper illustrates how a cognitive approach might better help us understand the purported functionality of these objects than has hitherto been the case. This approach, grounded in distributed cognition, draws on semiotics, figurative thought and communication theory and considers the priorities of both the theoretical sender and the theoretical receiver. The perspective of the sender comprises what could actually be built, given the confines of material, size, space and budget. The perspective of the receiver is tied to the factors that guarantee intelligibility, such as cultural primaries, medial awareness and aesthetic priming. It is argued that many of the cognitive processes driving comprehension may be based on transfer processes transcending culture and aesthetics, such as metonymy and metaphor, which occur both in the linguistic and the visual modality. In this way, we can ground discussions of model production and use in more fine-grained theoretical and methodological frameworks and achieve new insights into the communicative power of these objects.

The recent discovery of animal carvings in the Early Bronze Age burial cairn at Dunchraigaig (Kilmartin Glen, Scotland) prompts a re-evaluation of current knowledge of rock art in Britain. The deer and other quadrupeds represented in the monument are the first unambiguous depictions of prehistoric animals of prehistoric date in Scotland, and among the earliest identified in Britain and Ireland. This contrasts with the well-known abstract carvings of rock art in this region, characterized by cup-marks and cup-and-rings. The discovery also reinforces the special character of Kilmartin Glen as one of the most original and remarkable Neolithic–Bronze Age landscapes of monumentality and rock art in Britain. This article describes the process of authenticating the Dunchraigaig carvings as part of the Scotland's Rock Art Project (ScRAP) and discusses their implications for our understanding of prehistoric rock art in Scotland, Britain and Atlantic Europe more widely.

Archaeological investigations have documented an ideological and occupied frontier in the Lower Tagali Valley along the southern margins of the Highlands of Papua New Guinea. Open-area excavations document two types of house structure associated with Huli occupation of the Lower Tagali Valley landscape, a women's house (wandia) and a lodge and ceremonial complex associated with a bachelor cult (ibagiyaanda). Excavation revealed the complete floor plan of the women's house site and multiple structural elements of the ceremonial complex. Radiocarbon dating provides a chronology for both sites that accords with genealogical histories for the colonization of this landscape by Huli during the early nineteenth century, or approximately eight generations ago. These archaeological findings are consistent with the strategies still employed today by Huli in the initial ideological incorporation of new territory and anchoring of expansionary claims through subsequent settlement and cultivation.

At the time of the Spanish invasion, central Andean society was organized around ayllus. These extensive social units, bound together by kinship, reciprocity, land claims, honoured ancestors and other criteria, are an example of the kin-based sodalities that have long been seen in political science as impediments to state development. Class should replace kin when large and complex polities like the Inca Empire form, and groups like the ayllu should fade away. This article seeks to re-evaluate the role played by kin-based sodalities in early state formation and expansion through a case study of the Wari State (ce 600–1000). We argue that the decades-long development of ayllus was a reaction to incipient urbanization, surging interregional interaction and the other challenges associated with Wari's rise. Ayllu development created a more heterarchical political structure that would endure some 200 years into the polity's existence. Elite efforts to consolidate power in the ninth century ce ultimately led to the polity's decline and highlight the need to develop more dynamic models of urbanization and state formation in the Andes and elsewhere.

This paper focuses upon alterity and how we can more fully embrace intimations of otherness in our dealings with prehistoric monuments. Taking as its inspiration recent attempts to explain such structures, and the landscapes of which they were part, it makes two arguments. First, that while ethnographic analogies offer a vital point of departure for thinking through the possibilities raised by alterity and otherness, we may well have been overlooking a rich set of data—derived from careful excavation and painstaking metrical analyses—that has been sitting in front of us for a very long time. Second, despite over a decade of sustained critical debate, we seem remarkably timid when it comes to seeing where these data might take us. Through the lens of two Late Neolithic stone circles from southern Britain (one big, one small), research into measurement units and alignments is allied with recent excavation and survey data in order to explore ideas of hybridity, nomad-geometry and the arresting/manipulation of time and motion. Placing these glimpses of alterity front and centre, they are then used to establish new starting-points for the interpretation of these structures.

Mortuary rituals are conservative and transformative. As practices of hands-on and conceptual learning, memory making, and inter-generational knowledge transfer they take place within Communities of Practice, where emotionality and temporalities shape learning about death, interment, and commemoration. Drawing on mortuary, ethnographic, and archaeothanatological evidence, this paper explores how inhabitants of the provincial Tiwanaku site Omo M10 (eighth–twelfth centuries ce) in southern Peru experienced and learned death and burial. The reconstruction of three stages of funerary ritual—body preparation, interment, and remembering—represents distinct episodes of bundling. During each stage, increasingly more diverse participants, materials, spaces, and activities differentially shape episodic memory formation and knowledge transfer. I propose that coming to understand the constituent participants, practices, and knowledge of mortuary ritual as emergent and heterogeneous Communities of Practice has important implications for the interpretation of synchronic and diachronic mortuary variability.
