Technological analysis and experimental reproduction of the techniques of perforation of quartz beads from the Ceramic period in the Antilles

Using Cactus Thorns to Drill Quartz: A Proof of Concept

Recommended by and ORCID_LOGO based on reviews by Viola Stefano, ? and 1 anonymous reviewer

Quartz adornments (beads, pendants, etc.) are frequent artifacts found in the Caribbean, particularly from Early Ceramic Age contexts (~500 BC-AD 700). As a form of specialization, these are sometimes seen as indicative of greater social complexity and craftsmanship during this time. Indeed, ethnographic analogy has purported that such stone adornments require enormous inputs of time and labor, as well as some technological sophistication with tools hard-enough to create the holes (e.g., metal or diamonds). However, given these limitations, one would expect unfinished beads to be a common artifact in the archaeological record. Yet, whereas unworked/raw materials are often found, beads with partial/unfinished perforations are not.
 
Could the perforations of stone beads be made using more accessible materials? Some ethnographic sources from Central America suggest certain plant materials could work. Thus, Raymond et al. (2022) endeavored to test the manufacturing process of stone beads by experimenting with several underrated (yet readily available) materials from the Caribbean: various species of wood, bone, thorns, and chert. As it turns out, thorns from an endemic cactus (Melocactus intortus) worked best and were actually harder than many of the other materials attempted. Even the chert drills were too large and fragile to be effective (neither are they found archaeologically). Using debitage powder from the rock itself, some water, and a basic bow drill mounted with a cactus thorn, the team successfully created perforations on unworked samples of quartz that were similar to those found archaeologically. This was corroborated by analyzing the results at different levels of magnification, including X-ray microtomography and SEM, and then comparing that to similar studies on ancient beads.
 
The results of this study offer useful parameters for the feasibility of bead craftsmanship in the ancient Caribbean. For one, all of the materials used are fairly common in the region, including quartz (although the source of amethyst in the Caribbean is believed to be Guyana (Cody 1990)). Additionally, the practice does not require much skill, as the authors (neophyte craftspeople) were able to replicate the holes. Presumably, a child could do this (an intriguing prospect). The study therefore offers practical data for the once mysterious production of precolumbian personal adornments. Indeed, the article indirectly offers arguments for the presence of bead crafting specialists in other areas of the world as well, where production of ornaments entails similar time investments and complexity. For example, similar quartz materials, like carnelian or agate, shaped into long barrels or cylindrical beads forming beautiful parures, are common to pre-metallic contexts of agro-pastoral societies of Europe and North Africa in the VI and V millennium BC.
 
That said, the huge time commitment (over 200 hours per bead), although far less than the years (or lifetimes) some researchers had previously estimated, socially translates into a distraction from subsistence activities, which may indicate the presence of individuals devoted (at least part-time) to producing non-utilitarian adornments (see also Kenoyer et al. 1991 on this topic). 
 
Focusing on the specific aspect of finding the most appropriate substitute to metal piercing devices and the related aspects of the overall chaîne opératoire, the document invites further research, for example on the bead locking system during the piercing phase, in the management of the force exerted during the process, and in the number of failures (and on their potential uses).

The Dynamic Collections – a 3D Web Platform of Archaeological Artefacts designed for Data Reuse and Deep Interaction

A comparative teaching and learning tool for 3D data: Dynamic Collections

Recommended by ORCID_LOGO based on reviews by Alex Brandsen and Louise Tharandt

The paper (Callieri, M. et al. 2023) describes the “Dynamic Collections” project, an online platform initially created to showcase digital archaeological collections of Lund University. During a phase of testing by department members, new functionalities and artefacts were added resulting in an interactive platform adapted to university-level teaching and learning. The paper introduces into the topic and related works after which it starts to explain the project itself. The idea is to resemble the possibilities of interaction of non-digital collections in an online platform. Besides the objects themselves, the online platform offers annotations, measurement and other interactive tools based on the already known 3DHOP framework. With the possibility to create custom online collections a collaborative working/teaching environment can be created.

The already wide-spread use of the 3DHOP framework enabled the authors to develop some functionalities that could be used in the “Dynamic Collections” project. Also, current and future plans of the project are discussed and will include multiple 3D models for one object or permanent identifiers, which are both important additions to the system. The paper then continues to explain some of its further planned improvements, like comparisons and support for teaching, which will make the tool an important asset for future university-level education.

The paper in general is well-written and informative and introduces into the interactive tool, that is already available and working. It is very positive, that the authors rely on up-to-date methodologies in creating 3D online repositories and are in fact improving them by testing the tool in a teaching environment. They mention several times the alignment with upcoming EU efforts related to the European Collaborative Cloud for Cultural Heritage (ECCCH), which is anticipatory and far-sighted and adds to the longevity of the project. Comments of the reviewers were reasonably implemented and led to a clearer and more concise paper. I am very confident that this tool will find good use in heritage research and presentation as well as in university-level teaching and learning.

Although the authors never answer the introductory question explicitly (What characteristics should a virtual environment have in order to trigger dynamic interaction?), the paper gives the implicit answer by showing what the "Dynamic Collections" project has achieved and is able to achieve in the future.

For our world without sound. The opportunistic debitage in the Italian context: a methodological evaluation of the lithic assemblages of Pirro Nord, Cà Belvedere di Montepoggiolo, Ciota Ciara cave and Riparo Tagliente.

Investigating the opportunistic debitage – an experimental approach

Recommended by based on reviews by David Hérisson and 1 anonymous reviewer

The paper “For our world without sound. The opportunistic debitage in the Italian context: a methodological evaluation of the lithic assemblages of Pirro Nord, Cà Belvedere di Montepoggiolo, Ciota Ciara cave and Riparo Tagliente” [1] submitted by M. Carpentieri and M. Arzarello is a welcome addition to a growing number of studies focusing on flaking methods showing little to no core preparation, e.g., [2–4]. These flaking methods are often overlooked or seen as ‘simple’, which, in a Middle Palaeolithic context, sometimes leads to a dichotomy of Levallois vs. non-Levallois debitage (e.g., see discussion in [2]).

The authors address this topic by first providing a definition for ‘opportunistic debitage’, derived from the definition of the ‘Alternating Surfaces Debitage System’ (SSDA, [5]). At the core of the definition is the adaptation to the characteristics (e.g., natural convexities and quality) of the raw material. This is one main challenge in studying this type of debitage in a consistent way, as the opportunistic debitage leads to a wide range of core and flake morphologies, which have sometimes been interpreted as resulting from different technical behaviours, but which the authors argue are part of a same ‘methodological substratum’ [1].

This article aims to further characterise the ‘opportunistic debitage’. The study relies on four archaeological assemblages from Italy, ranging from the Lower to the Upper Pleistocene, in which the opportunistic debitage has been recognised. Based on the characteristics associated with the occurrence of the opportunistic debitage in these assemblages, an experimental replication of the opportunistic debitage using the same raw materials found at these sites was conducted, with the aim to gain new insights into the method. Results show that experimental flakes and cores are comparable to the ones identified as resulting from the opportunistic debitage in the archaeological assemblage, and further highlight the high versatility of the opportunistic method.

One outcome of the experimental replication is that a higher flake productivity is noted in the opportunistic centripetal debitage, along with the occurrence of 'predetermined-like' products (such as déjeté points). This brings the authors to formulate the hypothesis that the opportunistic debitage may have had a role in the process that will eventually lead to the development of Levallois and Discoid technologies. How this articulates with for example current discussions on the origins of Levallois technologies (e.g., [6–8]) is an interesting research avenue. This study also touches upon the question of how the implementation of one knapping method may be influenced by the broader technological knowledge of the knapper(s) (e.g., in a context where Levallois methods were common vs a context where they were not). It makes the case for a renewed attention in lithic studies for flaking methods usually considered as less behaviourally significant.

Light in the Cave: Opal coating detection by UV-light illumination and fluorescence in a rock art context. Methodological development and application in Points Cave (Gard, France)

New method for the in situ detection and characterisation of amorphous silica in rock art contexts

Recommended by based on reviews by Alain Queffelec, Laure Dayet and 1 anonymous reviewer

Silica coating developed in cave art walls had an impact in the preservation of the paintings themselves. Despite it still exists a controversy about whether or not the effects contribute to the preservation of the artworks; it is evident that identifying these silica coatings would have an impact to assess the taphonomy of the walls and the paintings preserved on them. Unfortunately, current techniques -especially non-invasive ones- can hardly address amorphous silica characterisation. Thus, its presence is often detected on laboratory observations such as SEM or XRD analyses. In the paper “Light in the Cave: Opal coating detection by UV-light illumination and fluorescence in a rock art context - Methodological development and application in Points Cave (Gard, France)”, Quiers and collaborators propose a new method for the in situ detection and characterisation of amorphous silica in a rock art context based on UV laser-induced fluorescence (LIF) and UV illumination [1].

The results from both methods presented by the authors are convincing for the detection of U-silica mineralisation (U-opal in the specific case of study presented). This would allow access to a fast and cheap method to identify this kind of formations in situ in decorated caves. Beyond the relationship between opal coating and the preservation of the rock art, the detection of silica mineralisation can have further implications. First, it can help to define spot for sampling for pigment compositions, as well as reconstruct the chronology of the natural history of the caves and its relation with the human frequentation and activities. In conclusion, I am glad to recommend this original research, which offers a new approach to the identification of geological processes that affect -and can be linked with- the Palaeolithic cave art.

The Games of our People. Analysing Populist Nationalist Rhetorics of the Past in Historical Games

A framework for the analysis of populist nationalist rhetorics in historical games

Recommended by ORCID_LOGO based on reviews by Angus Mol, Aris Politopoulos and 1 anonymous reviewer

This paper by Visonà and Cassone (2024) looks on historic video games and populist national rhetoric of the past with the goal of understanding the political implications of historical games today. Based on the works of Chapman et al. (2017) and Reinhard (2018), the paper focuses on political rhetoric and the possibility to provide forms of friction or alternative historical experiences. The paper wants to present an analytical framework to investigate these possibilities in video games and is structured into four parts.

Part 1 (history and digital games) gives a short introduction into the topic of archaeogaming and the development in researching different aspects of video games. It also briefly introduces into the mechanics of knowledge transfer (see also Giere 2019). Part 2 (populist nationalism and the construction of the past) explains the dynamics of populist nationalism of the past and how these same mechanisms are on the rise again today. This makes this paper extremely relevant to today's political situation. Populist movements try to construct a past to form identity, a past that never really existed. These movements then use these identities to justify their political goals.Part 3 (analytical framework) describes the authors framework for analysis. It is structured into a matrix of three dimensions (Identitarian mythopoesis, Unavoidable conflict, Western teleology) by three procedures (Perspective, Connection, Selection), each with distinct questions to ask and answer for the researched video game. Part 4 (implementation) finally discusses how the framework works and presents some practical examples with the help of the games Assassin’s Creed III and Civilization V. The conclusions summarize the paper once more very briefly.

The proposed framework is a very welcome tool in reflecting on video games in terms of the political dimensions represented. The matrix provided can give a hint on what questions to ask and how to analyze the answers. Nevertheless, a little more explanation on how to work with these questions might be helpful, especially for students wanting to utilize this matrix. The two provided examples help a lot, but it might not be clear to everyone how to use the framework. If one does however, this framework can help tremendously in video game analysis with a political focus. This is especially important today with raising populist narratives all over the world. This paper presents a very good starting point on an analytical framework for the analysis of historical video games.

Towards a Mobile 3D Documentation Solution. Video Based Photogrammetry and iPhone 12 Pro as Fieldwork Documentation Tools

The Potential of Mobile 3D Documentation using Video Based Photogrammetry and iPhone 12 Pro

Recommended by based on reviews by Dominik Hagmann, Sebastian Hageneuer and 1 anonymous reviewer

I am pleased to recommend the paper titled "Towards a Mobile 3D Documentation Solution. Video Based Photogrammetry and iPhone 12 Pro as Fieldwork Documentation Tools" for consideration and publication as a preprint (Paukkonen, 2023). The paper addresses a timely and relevant topic within the field of archaeology and offers valuable insights into the evolving landscape of 3D documentation methods.

The advances in technology over the past decade have brought about significant changes in archaeological documentation practices. This paper makes a valuable contribution by discussing the emergence of affordable equipment suitable for 3D fieldwork documentation. Given the constraints that many archaeologists face with limited resources and tight timeframes, the comparison between photogrammetry based on a video captured by a DJI Osmo Pocket gimbal camera and iPhone 12 Pro LiDAR scans is of great significance.

The research presented in the paper showcases a practical application of these new technologies in the context of a Finnish Early Modern period archaeological project. By comparing the acquisition processes and evaluating the accuracy, precision, ease of use, and time constraints associated with each method, the authors provide a comprehensive assessment of their potential for archaeological fieldwork. This practical approach is a commendable aspect of the paper, as it not only explores the technical aspects but also considers the practical implications for archaeologists on the ground.

Furthermore, the paper appropriately addresses the limitations of these technologies, specifically highlighting their potential inadequacy for projects requiring a higher level of precision, such as Neolithic period excavations. This nuanced perspective adds depth to the discussion and provides a realistic portrayal of the strengths and limitations of the new documentation methods.

In conclusion, the paper offers valuable insights into the future of 3D field documentation for archaeologists. The authors' thorough evaluation and practical approach make this study a valuable resource for researchers, practitioners, and professionals in the field. I believe that this paper would be an excellent addition to PCIArchaeology and would contribute significantly to the ongoing dialogue within the archaeological community.

Faunal remains from the Upper Paleolithic site of Nahal Rahaf 2 in the southern Judean Desert, Israel

New zooarchaeological data from the Upper Palaeolithic site of Nahal Rahaf 2, Israel

Recommended by ORCID_LOGO based on reviews by Ana Belén Galán and Joana Gabucio

The Levantine Corridor is considered a crossing point to Eurasia and one of the main areas for detecting population flows (and their associated cultural and economic changes) during the Pleistocene. This area could have been closed during the most arid periods, giving rise to processes of population isolation between Africa and Eurasia and intermittent contact between Eurasian human communities [1,2]. 

Zooarchaeological studies of the early Upper Palaeolithic assemblages constitute an important source of knowledge about human subsistence, making them central to the debate on modern behaviour. The Early Upper Palaeolithic sequence in the Levant includes two cultural entities – the Early Ahmarian and the Levantine Aurignacian. This latter is dated to 39-33 ka and is considered a local adaptation of the European Aurignacian techno-complex. In this work, the authors present a zooarchaeological study of the Nahal Rahaf 2 (ca. 35 ka) archaeological site in the southern Judean Desert in Israel [3].

Zooarchaeological data from the early Upper Paleolithic desert regions of the southern Levant are not common due to preservation problems of non-lithic finds. In the case of Nahal Rahaf 2, recent excavation seasons brought to light a stratigraphical sequence composed of very well-preserved archaeological surfaces attributed to the 'Arkov-Divshon' cultural entity, which is associated with the Levantine Aurignacian. 

This study shows age-specific caprine (Capra cf. Capra ibex) hunting on prime adults and a generalized procurement of gazelles (Gazella cf. Gazella gazella), which seem to have been selectively transported to the site and processed for within-bone nutrients. An interesting point to note is that the proportion of goats increases along the stratigraphic sequence, which suggests to the authors a specialization in the economy over time that is inversely related to the occupational intensity of use of the site. 

It is also noteworthy that the materials represent a large sample compared to previous studies from the Upper Paleolithic of the Judean Desert and Negev.

In summary, this manuscript contributes significantly to the study of both the palaeoenvironment and human subsistence strategies in the Upper Palaeolithic and provides another important reference point for evaluating human hunting adaptations in the arid regions of the southern Levant.

A note on predator-prey dynamics in radiocarbon datasets

A new approach to Predator-prey dynamics

Recommended by ORCID_LOGO based on reviews by Jesús Rodríguez, Miriam Belmaker and 1 anonymous reviewer

Various biological systems have been subjected to mathematical modelling to enhance our understanding of the intricate interactions among different species. Among these models, the predator-prey model holds a significant position. Its relevance stems not only from its application in biology, where it largely governs the coexistence of diverse species in open ecosystems, but also from its utility in other domains. 

Predator-prey dynamics have long been a focal point in population ecology, yet access to real-world data is confined to relatively brief periods, typically less than a century. Studying predator-prey dynamics over extended periods presents challenges due to the limited availability of population data spanning more than a century. The most extensive dataset is the hare-lynx records from the Hudson Bay Company, documenting a century of fur trade [1]. However, other records are considerably shorter, usually spanning decades [2,3]. This constraint hampers our capacity to investigate predator-prey interactions over centennial or millennial scales. 

Marom and Wolkowski [4] propose here that leveraging regional radiocarbon databases offers a solution to this challenge, enabling the reconstruction of predator-prey population dynamics over extensive timeframes. To substantiate this proposition, they draw upon examples from Pleistocene Beringia and the Holocene Judean Desert. This approach is highly relevant and might provide insight into ecological processes occurring at a time scale beyond the limits of current ecological datasets. 

The methodological approach employed in this article proposes that the summed probability distribution (SPD) of predator radiocarbon dates, which reflects changes in population size, will demonstrate either more or less variation than anticipated from random sampling in a homogeneous distribution spanning the same timeframe. A deviation from randomness would imply a covariation between predator and prey populations. This basic hypothesis makes no assumptions about the frequency, mechanism, or cause of predator-prey interactions, as it is assumed that such aspects cannot be adequately tested with the available data. If validated, this hypothesis would offer initial support for the idea that long-term regional radiocarbon data contain signals of predator-prey interactions. This approach could justify the construction of larger datasets to facilitate a more comprehensive exploration of these signal structures.

Recommended by based on reviews by Antony Borel, Atefeh Shekofteh, Andrea Squitieri, Birgül Ögüt, Atefe Shekofte and 1 anonymous reviewer

​​This paper [1] covers an interesting topic in that it presents through ethnography an insight into a traditional method of food production which is gradually declining in use. In addition to preserving traditional knowledge, the ethnographic study of grinding stones has the potential for showing how similar tools may have been used by people in the past, particularly from the same geographic region.

Social Network Analysis, Community Detection Algorithms, and Neighbourhood Identification in Pompeii

A Valuable Contribution to Archaeological Network Research: A Case Study of Pompeii

Recommended by ORCID_LOGO based on reviews by Matthew Peeples, Isaac Ullah and Philip Verhagen

The paper entitled 'Social Network Analysis, Community Detection Algorithms, and Neighbourhood Identification in Pompeii' [1] presents a significant contribution to the field of archaeological network research, particularly in the challenging task of identifying urban neighborhoods within the context of Pompeii. This study focuses on the relational dynamics within urban neighborhoods and examines their indistinct boundaries through advanced analytical methods. The methodology employed provides a comprehensive analysis of community detection, including the Louvain and Leiden algorithms, and introduces a novel Convex Hull of Admissible Modularity Partitions (CHAMP) algorithm. The incorporation of a network approach into this domain is both innovative and timely.

The potential impact of this research is substantial, offering new perspectives and analytical tools. This opens new avenues for understanding social structures in ancient urban settings, which can be applied to other archaeological contexts beyond Pompeii. Moreover, the manuscript is not only methodologically solid but also well-written and structured, making complex concepts accessible to a broad audience.

In conclusion, this study represents a valuable contribution to the field of archaeology, particularly for archaeological network research. Their results not only enhance our knowledge of Pompeii but also provide a robust framework for future studies in similar historical contexts. Therefore, this publication advances our understanding of social dynamics in historical urban environments. The rigorous analysis, combined with the innovative application of network algorithms, makes this study a noteworthy addition to the existing body of network science literature. It is recommended for a wide range of scholars interested in the intersection of archaeology, history, and network science.
