Removing Barriers to Reproducible Research in ArchaeologyEmma Karoune and Esther Plomp https://doi.org/10.5281/zenodo.7320029
Three levels of reproducible workflow remove barriers for archaeologists and increase accessibilityRecommended by Ben Marwick based on reviews by Sam Leggett, Cyler Conrad, Cheng Liu and Lisa Lodwick
Over the last decade, a small but growing community of archaeologists, from a diversity of intellectual and demographic backgrounds, have been striving for computational reproducibility in their published research. In their survey of the accomplishments of this thriving community, Emma Karoune and Esther Plomp (2022) analyzed the wide variety of approaches researchers have taken to enhance the reproducibility of their research. A key contribution of this paper is their excellent synthesis of diverse approaches into three levels of increasing complexity. This is helpful because it provides multiple entry points for researchers new to the challenge of fortifying their research. Many researchers assume that computational reproducibility is only achievable if they have a high degree of technical skill with computers, or is only necessary if their work is very computationally intensive. Karoune and Plomp give three compelling reasons why reproducibility is important for all archaeological research, and through their three levels they demonstrate that how these levels can be accomplished with basic, non-specialized computer skills and widely used free software. They showcase exemplary work from a variety of archaeologists to show how practical and achievable reproducible research is for all archaeologists. They advocate for archaeologists to use the most widely used and supported tools and services to support their reproducible research, such as the R and Python programming languages for data analysis, and Git and GitHub for collaboration.
This paper, with its extensive appendix including thoughtful responses to frequently asked questions about reproducible research in archaeology, is likely to have a wide reach and influence, beyond previous works on this topic that have largely focused on technical details. Karoune and Plomp have provided the on-ramp for a generation of archaeologists who will find their questions about reproducible research answered here. They will also find an agreeable entry point to reproducible research in one of the three levels described by the authors. Will every archaeologist embrace this way of working? Should they? The work of Leonelli (2018) can help us anticipate the answers to these questions. Leonelli asks where are the limits to reproducibility, and how do the characteristics of different ways of knowing affect the desirability of reproducibility? Leonelli's work invites us to consider that there will be archaeologists coming from different epistemic cultures for whom the motivations presented by Karoune and Plomp will not resonate. For example, archaeologists engaged in mostly hermeneutical social science and humanities research, who do little or no quantitative analysis and statistics, are unlikely to see reproducibility as meaningful or desirable for their work. We can describe these researchers as working in interpretative or constructivist epistemic cultures. In these cultures, the particulars of how an individual researcher engages with their subject are exclusive and unique, and they would argue it cannot be fully captured or shared in an meaningful way (Elman and Kapiszewski 2017). Here, knowledge is situational, emerging from a specific, once-off combination of people and circumstances. One example in archaeology is the chaîne opératoire approach of stone artefact analysis, which Monnier and Missal (2014:61) describe as "based upon the analyst's experience and intuition, and it is not replicable, nor quantifiable". To make sense of this example we can draw on Galison's (1997) concept of 'image traditions' and 'logic traditions'. An image tradition is a way of knowing that is qualitative, based on composing narratives from drawings and photographs. A logic tradition is based on the use of instruments and statistical methods to collect standardised quantitative data. Chaîne opératoire approaches fall into the image tradition, along with many other ways of working in archaeology that do not generate numbers or use them to support claims about the past. Archaeologists working in a logic tradition will find reproducible research to be more meaningful than those working in an image tradition.
We should be mindful not to claim that one epistemic culture is superior to another because reproducibility is not meaningful or attainable for researchers in one culture. Such a claim would threaten the plurality that is essential for the reliability of scientific knowledge (Massimi 2022). Instead we should identify those communities in archaeology where reproducible research is both meaningful and attainable, but has not yet been widely embraced. That is the where the most beneficial effects can be expected. According to Leonelli's (2018) framework, we can recognise these communities by a few basic characteristics. For example: they are doing computationally intensive archaeology, such as using or writing software to collect, simulate, analyse or visualise data; they are doing experimental archaeology; or they are making knowledge claims that are supported by tables of numeric data and data visualisations. Archaeologists whose work shares one or more of these characteristics will find the guidance provided here by Karoune and Plomp to be highly instructive and relevant, and stand the most to benefit from it.
But it is not only individual archaeological scientists that have potential to benefit from how Karoune and Plomp have lowered the barriers to reproducible research. An especially important implication of this paper is that by lowering the barriers to reproducible research, Karoune and Plomp help us all to lower barriers to participation in archaeology in general. Documenting our research transparently, and sharing our materials (such as data and code and so on) openly, can profoundly change how others can participate in archaeology. By doing this, we are enabling students and researchers elsewhere, for example in low and middle income locations, to use our materials in their teaching and learning. Other researchers and students can apply our methods to their data, and combine their data with ours to achieve syntheses beyond what a single project can do. Similarly, for archaeologists working with local, descendant or marginalized communities, the tools of reproducible research are vital for enabling community members to have full access to the archaeological process, and thus reproducibility may be considered a necessity for decolonising the discipline. Karoune and Plomp present the CARE principles (Carroll et al. 2020) to guide archaeologists in ensuring community control of data so that reproducibility can be ethically accomplished with community safety and well-being as a priority. This may have a profoundly positive impact on the demographics of archaeology, as it lowers the barriers of meaningful participation by people far beyond our immediate groups of collaborators.
Making archaeology more accessible is of critical importance in stemming the negative social impacts of pseudoarchaeologists, who often claim that archaeologists actively suppress the truth of the archaeological record through secrecy, elitism, and exclusiveness. The harm in this is twofold. First, that pseudoarchaeology typically erases Indigenous heritage by claiming that their past achievements were due to an ancient, extinct advanced civilization, not Indigenous people. These claims are often adopted by white supremacists to support racist and antisemitic conspiracy theories (Turner and Turner 2021), which sometimes leads to prejudice, physical violence, radicalization and extremism. A second type of harm that can come from claims of secrecy and elitism is it drains public trust in experts, leading to science denial. Not only trust in archaeologists, but trust in many kinds of experts, including those working on urgent contemporary issues such as public health and climate change. Karoune and Plomp's work is important here because it provides a practical and affordable pathway for archaeologists to fight claims of secrecy and elitism by sharing their work in ways that make it possible for non-academics to inspect the analyses and logic in detail. Claims of secrecy and elitism can be easily countered by openness, transparently and reproducibility by archaeologists. This is not only useful for tackling pseudoarchaeologists, but also in enacting an ethic of care, framing members of the public as people that not only care about archaeology as part of humanity's shared heritage, but also care for the construction of reliable interpretations of the archaeological record to provide secure and authentic foundations for their social identities and relationships (Wylie et al 2018; de la Bellacasa 2011). By striving for reproducible research in the way described by Karoune and Plomp, we are practicing a kind of reciprocal care among ourselves as archaeologists, and between archaeologists and members of the public as two communities who care about the human past.

Archaeophenomics of ancient domestic plants and animals using geometric morphometrics : a reviewAllowen Evin, Laurent Bouby, Vincent Bonhomme, Angèle Jeanty, Marine Jeanjean, Jean-Frédéric Terral https://doi.org/10.31219/osf.io/skeu5
Archaeophenomics: an up-and-coming field in bioarchaeologyRecommended by Anneke H. van Heteren based on reviews by Stefan Schlager and 1 anonymous reviewer

Phenomics is the analysis of high-dimensional phenotypic data . Phenomics research strategies are capable of linking genetic variation to phenotypic variation , but a genetic component is not absolutely necessary. The paper “Archaeophenomics of ancient domestic plants and animals using geometric morphometrics: a review” by Evin and colleagues  examines the use of geometric morphometrics in bioarchaeology and coins the term archaeophenomics. Archaeophenomics can be described as the large-scale phenotyping of ancient remains, and both addresses taxonomic identification, as well as infers spatio-temporal agrobiodiversity dynamics. It is a relatively new field in bioarchaeology with the first paper using this approach stemming from 2004. This study by Evin et al.  presents an excellent review and unquestionably demonstrates the potential of archaeophenomics.
The authors provide an exhaustive review specifically of bioarchaeological studies in international journals using geometric morphometrics to study archaeological remains of domestic species. Although geometric morphometrics lends itself well for archaeophenomics, readers should keep in mind that this is not the only method and other approaches might equally fall under archaeophenomics as long as high-dimensional phenotypic archaeological data are involved.
Distinguishing archaeophenomics from phenomics is important because of a critical difference. Archaeological remains are often altered by taphonomical processes. As such data may not be as complete as when working with modern specimens. Although this poses difficulties, morphometric analyses can usually still be performed as long as the structures presenting the relevant geometrical features are present. Even fragmented remains can be studied with a restricted version of the original landmarking/measurement protocol.
Evin et al.  define archaeophenomics as “phenomics of the past”. This is only partly correct. It can be deduced from their review that they really mean phenomics of our (human) past. This leaves a gap for phenomics of the non-human past, for which I suggest the term palaeophenomics.

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.Marco Carpentieri, Marta Arzarello https://doi.org/10.31219/osf.io/2ptjb
Investigating the opportunistic debitage – an experimental approachRecommended by Alice Leplongeon 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”  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 ).
The authors address this topic by first providing a definition for ‘opportunistic debitage’, derived from the definition of the ‘Alternating Surfaces Debitage System’ (SSDA, ). 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’ .
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.

Experimentation as a driving force for innovation in the Pre-Still Bay from Southern AfricaRecommended by Anne Delagnes based on reviews by Francesco d'Errico, Enza Elena Spinapolice and Kathryn Ranhorn
The article submitted by Guillaume Porraz et al.  shed light on the evolutionary changes recorded during the Pre-Still Bay Lynn stratigraphic unit (SU) from Diepkloof (Southern Africa). It promotes a multi-proxy and integrative approach based on a set of innovative behaviors, such as the engraving of geometric forms, silcrete heat- treatment, the use of adhesive, bladelet and bifacial tools production. This approach is not so common in Middle Stone Age (MSA) studies and makes a lot of sense for discussing the mechanisms that have fostered later innovations during the Still Bay and Howiesons Poort periods. The various innovations that emerge synchronously in this layer contrast with earlier innovations which appear as isolated phenomena in the MSA archaeological record. The strong inventiveness documented in Lynn SU is reported to a phase of experimentation for testing new ideas, new behaviors that would have played a crucial role for the emergence of the Still Bay in a context of socio-economic transformation.
The data presented in this article broadens the scope of two previous articles [2-3] based on a more representative record, collected on an area of 3,5 m² opposed to 2 m² previously, and on the first presentation and description of an engraved bone with a rhomboid pattern. Macro- and microscopic analyses together with the analysis of the distribution of the engraved lines argue convincingly for an intentional engraving. This article constitutes a key contribution to the question of HOW emerged modern cultures in Southern Africa, while calling for further research related to sites’ function, environment and local resources to address the ever-debated question of WHY the MSA groups from Southern Africa developed such unprecedented inventiveness. It makes no doubt that this article deserves recommendation by PCI Archaeology.

Caching up with the study of the procurement of symbolic raw materials in the Upper PalaeolithicRecommended by Beatrice Demarchi based on reviews by Begoña Soler Mayor , Catherine Dupont and Lawrence Straus
The manuscript "The management of symbolic raw materials in the Late Upper Paleolithic of South-Western France: a shell ornaments perspective" by Solange Rigaud and colleagues (Rigaud et al. 2022) is a perfect demonstration that appropriate scientific methodologies can be used effectively in order to enhance the historical value of findings from “old” collections, despite the lack of secure stratigraphic and contextual data. The shell assemblage (n = 377) investigated here (from Rochereil, Dordogne) had been excavated during the first half of the 20th century (Jude 1960) and reported in 1993 (Taborin 1993), but only this recent analysis revealed that it was composed of largely unmodified mollusc shells, most of allochthonous origin. Rigaud et al. interpret this finding as the raw materials used to produce personal ornaments. This is especially significant, because the focus of research has been on the manufacture, use and exchange of personal ornaments in prehistory, much less so on the procurement of the raw materials. As such, the manuscript adds substantially to the growing literature on Magdalenian social networks.
The authors carried out detailed taxonomic analysis based on morphological and morphometric characteristics and identified at least nine different species, including Dentalium sp., Ocenebra erinaceus, Tritia reticulata and T. gibbosula, as well as some bivalve specimens (Mytilus, Glycymeris, Spondylus, Pecten). Most of the species are commonly found in personal ornament assemblages from the Magdalenian, reflecting intentional selection (also shown by the size sorting of some of the taxa), and cultural continuity. However, microscopic examinations revealed securely-identified anthropogenic modifications on a very limited number of specimens: one Glycymeris valve (used as an ochre container), one Cardiidae valve (presence of a groove), one perforated Tritia gibbosula and two perforated Tritia reticulata bearing striations. The authors interpret this combination of anthropogenic vs natural “signals” as signifying that the assemblage represents raw material selected and stored for further processing.
Assessing the provenance and age of the shells is therefore paramount: the shells found at Rochereil belong to species that can be found on both the Atlantic and Mediterranean coasts. Assuming that molluscan taxa distribution in the past is comparable to that for the present day, this implies the exploitation of two catchment areas and long-distance transportation to the site: taking sea-level changes into account, during the Magdalenian the Mediterranean used to lie at a distance of 350 km from Rochereil, and the Atlantic was not significantly closer (~200 km). Importantly, exploitation of fossil shells cannot be discounted on the basis of the data presented here; direct dating of some of the specimens (e.g. by radiocarbon, or amino acid racemisation geochronology) would be beneficial to clarify this issue and in general to improve chronological control on the accumulation of shells. Nonetheless, the authors argue that the closest fossil deposits also lie more than 200 km away from the site, thus the material is allochthonous in origin.
In synthesis, the Rochereil assemblage represents an important step towards a better understanding of the procurement chain and of the production of ornaments during the European Upper Palaeolithic.

Probabilistic Modelling using Monte Carlo Simulation for Incorporating Uncertainty in Least Cost Path Results: a Roman Road Case StudyJoseph Lewis https://doi.org/10.31235/osf.io/mxas2
A probabilistic method for Least Cost Path calculation.Recommended by Otis Crandell based on reviews by Georges Abou Diwan and 1 anonymous reviewer
The paper entitled “Probabilistic Modelling using Monte Carlo Simulation for Incorporating Uncertainty in Least Cost Path Results: a Roman Road Case Study”  submitted by J. Lewis presents an innovative approach to applying Least Cost Path (LCP) analysis to incorporate uncertainty of the Digital Elevation Model used as the topographic surface on which the path is calculated.
The proposition of using Monte Carlo simulations to produce numerous LCP, each with a slightly different DEM included in the error range of the model, allows one to strengthen the method by proposing a probabilistic LCP rather than a single and arbitrary one which does not take into account the uncertainty of the topographic reconstruction. This new method is integrated in the R package leastcostpath .
The author tests the method using a Roman road built along a ridge in Cumbria, England. The integration of the uncertainty of the DEM, thanks to Monte Carlo simulations, shows that two paths could have the same probability to be the real LCP. One of them is indeed the path that the Roman road took. In particular, it is one of two possibilities of LCP in the south to north direction.
This new probabilistic method therefore strengthens the reconstruction of past pathways, while also allowing new hypotheses to be tested, and, in this case study, to suggest that the northern part of the Roman road’s location was selected to help the northward movements.

Technological analysis and experimental reproduction of the techniques of perforation of quartz beads from the Ceramic period in the AntillesMadeleine Raymond, Pierrick Fouéré, Ronan Ledevin, Yannick Lefrais and Alain Queffelec https://osf.io/preprints/socarxiv/a5tgp
Using Cactus Thorns to Drill Quartz: A Proof of ConceptRecommended by Donatella Usai and Jonathan Hanna based on reviews by Kozuch Laura, 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.

Platforms of Palaeolithic knappers reveal complex linguistic abilitiesCédric Gaucherel and Camille Noûs https://doi.org/10.31233/osf.io/wn5za
The means of complexity in a lithic reduction sequenceRecommended by Marta Arzarello based on reviews by Antony Borel and 1 anonymous reviewer
The paper entitled “Platforms of Palaeolithic knappers reveal complex linguistic abilities”  submitted by C. Gaucherel and C. Noûs represents an interesting reflection about the possibilities to detect the human cognitive abilities in relation to the lithic production.
The definition and the study of human cognitive abilities during the Lower Palaeolithic it has always been a complex field of investigation. The relation between the technical skills (lithic production) and the emergence of the linguistic abilities is not easy to investigate due to the difficulty of finding objective data to refer to. The proposition, made by C. Gaucherel and C. Noûs, of a formal grammar of knapping as a method to study the syntactical organisation of the reduction sequences, constitute a new and theoretical useful approach.
In order to effectively and precisely define the gestures linked to a specific reduction sequence, for example that of the handaxes shaping, a very large number of variables should be taken into consideration (morphology and quality of the raw material, experience of the knapper, context, percussion technique, forecast of use of the handaxe, etc.). But since a simplification, that brings more elements than the classic one [2,3] is needed, the “action grammar approach” can be a good instrument to detect the common element in a shaping reduction sequence. Furthermore, one of the advantages of the proposed methodology lies in the fact that the definition of the different STs (Stone Technology) can be done according to the technological specific characteristics to be studied and to the type of instrument produced.
The deconstruction of knapping sequences could help to detect the degree of complexity of the different steps of the reduction sequences also thanks to the identification of the sub-actions types. The increasing/decreasing of complexity is a very complicate concept in lithic technology. Since at the base of the lithic production there are two basic concepts (angle between the striking platform and the debitage surface - convexity of the debitage/façonnage surface) which are simply declined in an increasingly complex way, it is not easy to define uniquely in what exactly consists the increase in complexity. The approach proposed in the paper “Platforms of Palaeolithic knappers reveal complex linguistic abilities” can help to have new evidences, according to the identification of the required cognitive abilities.
The proposed example of formal grammar still needs to be confirmed on archaeological collections, but it is probable that a practical application will allow to further develop the methodology and possibly to highlight additional possibilities of the approach.

Surface texture analysis in Toothfrax and MountainsMap® SSFA module: Different software packages, different results?Ivan CALANDRA, Konstantin BOB, Gildas MERCERON, François BLATEYRON, Andreas HILDEBRANDT, Ellen SCHULZ-KORNAS, Antoine SOURON, Daniela E. WINKLER https://doi.org/10.5281/zenodo.4671438
An important comparison of software for Scale Sensitive Fractal Analysis : are ancient and new results compatible?Recommended by Alain Queffelec and Florent Rivals based on reviews by Antony Borel and 2 anonymous reviewers
The community of archaeologists, bioanthropologist and paleontologists relying on tools use-wear and dental microwear has grown in the recent years, mainly driven by the spread of confocal microscopes in the laboratories. If the diversity of microscopes is quite high, the main software used for 3D surface texture data analysis are mostly different versions of the same Mountains Map core. In addition to this software, since the beginning of 3D surface texture analysis in dental microwear, surface sensitive fractal analysis (SSFA) initially developed for industrial research (Brown & Savary, 1991) have been performed in our disciplines with the Sfrax/Toothfrax software for two decades (Ungar et al., 2003). This software being discontinued, these calculations have been integrated to the new versions of Mountains Map, with multi-core computing, full integration in the software and an update of the calculation itself.
New research based on these standard parameters of surface texture analysis will be, from now on, mainly calculated with this new add-on of Mountains Map, and will be directly compared with the important literature based on the previous software. The question addressed by Calandra et al. (2022), gathering several prominent researchers in this domain including the Mountains Map developer F. Blateyron, is key for the future research: can we directly compare SSFA results from both software?
Thanks to a Bayesian approach to this question, and comparing results calculated with both software on three different datasets (two on dental microwear, one on lithic raw materials), the authors show that the two software gives statistically different results for all surface texture parameters tested in the paper. Nevertheless, applying the new calculation to the datasets, they also show that the results published in original studies with these datasets would have been similar. Authors also claim that in the future, researchers will need to re-calculate the fractal parameters of previously published 3D surfaces and cannot simply integrate ancient and new data together.
We also want to emphasize the openness of the work published here. All datasets have been published online and will be probably very useful for future methodological works. Authors also published their code for statistical comparison of datasets, and proposed a fully reproducible article that allowed the reviewers to check the content of the paper, which can also make this article of high interest for student training.
This article is therefore a very important methodological work for the community, as noted by all three reviewers. It will certainly support the current transition between the two software packages and it is necessary that all surface texture specialists take these results and the recommendation of authors into account: calculate again data from ancient measurements, and share the 3D surface measurements on open access repositories to secure their access in the future.

Raphana of the Decapolis and its successor Arpha - The search for an eminent Greco-Roman CityJens Kleb https://doi.org/10.6084/m9.figshare.20550021
Cross-comparison of classical sources, explorer and scientific reports and maps in the search of an ancient city: The example of Raphana of the DecapolisRecommended by Luc Doyon based on reviews by Rocco Palermo and Francesca Mazzilli
Establishing the precise location of ancient cities constitutes a challenging task that requires the implementation of multi-disciplinary approaches. In his manuscript entitled “Raphana of the Decapolis and its successor Arpha: The search of an eminent Greco-Roman city”, Kleb (2022) proposes a convincing argument building on in-depth research of classical literary sources, literature review of explorer accounts and scientific publications from the 19th and 20th century as well as analysis of old and new maps, aerial photographs, and satellite images. This research report clearly emphasizes the importance of undertaking systematic interdisciplinary work on the topic to mitigate the uncertainties associated with the identification of Raphana, the Decapolis city first mentioned by Pliny the Elder.
The Decapolis refers to a group of ten cities of Hellenistic traditions located on the eastern borders of the Roman Empire. This group of cities plays an important role in research that aims to contextualize the Judaean and Galilean history and to investigate urban centers in which different local and Greco-Roman influences met (Lichtenberger, 2021). While the location of most of the Decapolis cities is known and is (or was) subjected to systematic archaeological investigations (e.g., Eisenberg and Kowalewska, 2022; Makhadmeh et al., 2020; Shiyab et al., 2019), the location of others remain speculative. This is the case of Raphana for which the precise location remains difficult to establish owing in part to numerous name changes, limited information on the city structure, architecture, and size, etc.
The research presented by Kleb (2022) has some merits, which is emphasized here, although the report is presented in an unusual format compared to traditional scientific articles, i.e., introduction, research background, methodology, results, and discussion. First, the extensive review of classical works allows the reader to gain a historical perspective on the change of names from Raepta/Raphana to Arpha/Arefa. The author argues these different names likely refer to a single location. Second, the author combs through an impressive literature from the 19th and 20th century and emphasize how some assumptions by explorers who visited the region were introduced in the scientific literature and remained unchallenged. Finally, the author gathers a remarkable quantity of old and new maps of the Golan, el-Ledja and Hauran regions and compare them with multiple lines of evidence to hypothesize that the location of Raphana may lie near Ar-Rafi’ah, also known as Bir Qassab, in the Ard el Fanah plain, a conclusion that now requires to be tested through fieldwork investigations.
