Rabbinic Evidence for the Spread of Roman Legal Education in the Provinces

Law and History Review, forthcoming
Abstract:
A long tradition of comparative scholarship has succeeded to establish the impact of Roman legal environment on rabbinic law making during the first two centuries CE, particularly in the field of family and status. Yet, the specific channels for acquiring this knowledge have hitherto remained a matter of conjecture. This paper argues that the rabbis were exposed to the contents of the current legal handbooks. Tractate Qiddushin (on betrothal) of the Mishnah includes two peculiar units: the first (1.1–5) regarding forms of acquisition and the second (3.12) on the status of newborns. Both units appear in key points in the tractate and exhibit striking structural and conceptual similarities to extended portions of the Roman school tradition regarding the laws of status, as handed down in Gaius’ Institutes and Pseudo-Ulpian's liber singularis regularum. It is therefore suggested that these units provide the earliest literary attestation already around the turn of the third century CE for the dissemination of Roman legal education among non-Roman provincials in the East, who sought to adjust their local practices into Roman-like legal structures.
From North Asia to South America: Tracing the longest human migration through genomic sequencing

Science, 15 May 2025
Abstract:
Genome sequencing of 1537 individuals from 139 ethnic groups reveals the genetic characteristics of understudied populations in North Asia and South America. Our analysis demonstrates that West Siberian ancestry, represented by the Kets and Nenets, contributed to the genetic ancestry of most Siberian populations. West Beringians, including the Koryaks, Inuit, and Luoravetlans, exhibit genetic adaptation to Arctic climate, including medically relevant variants. In South America, early migrants split into four groups -- Amazonians, Andeans, Chaco Amerindians, and Patagonians -- ~13,900 years ago. Their longest migration led to population decline, whereas settlement in South America’s diverse environments caused instant spatial isolation, reducing genetic and immunogenic diversity. These findings highlight how population history and environmental pressures shaped the genetic architecture of human populations across North Asia and South America.
Carolingian Normandies: Shatter Zones, Small Polities, and Continuity in Maritime Neustria (c. 800–1050)

Abstract:
The “continuity” of the eleventh-century duchy of Normandy with the ninth-century Frankish world is examined through the concept of a “shatter zone,” as developed in Southeast Asian anthropology and Indigenous American history and archaeology. Northern France in the ninth and tenth centuries constituted a shatter zone, an area where political and cultural fragmentation caused by violence was significant. The process associated with the shatter zone played a crucial role in the formation of the emerging Normandy, as Norman rulers forged the micropolities -- fragments of the shatter zone -- into a distinct political entity.
Pre-Hispanic ritual use of psychoactive plants at Chavín de Huántar, Peru
John Rick et al.
Proceedings of the National Academy of Sciences, 13 May 2025
Abstract:
Ritual is broadly accepted as an important locus of social interaction in the pre-Hispanic Central Andes, and research into the development of durable sociopolitical inequality in the region often focuses on the social and political roles of public rituals. At the Middle-Late Formative Period (ca. 1200–400 BCE) monumental center of Chavín de Huántar, as well as at contemporary sites, ritual has long been hypothesized to include the use of psychoactive plants. However, neither psychoactive plant remains nor chemical traces of psychoactive compounds in likely ritual contexts have been identified at any of these sites. Recently excavated deposits sealed in an underground gallery at Chavín contained twenty-three artifacts of forms (especially bone tubes) associated with consumption of psychoactive plants elsewhere in the region. We here report, based on independent microbotanical and chemical analyses, two kinds of direct evidence for use of psychoactive plants in institutionalized ritual at Chavín. These results are direct evidence of psychoactive plants in archaeological bone tubes used as inhalers and the northernmost direct evidence of vilca and Nicotiana use in the pre-Hispanic Andes.
Direct evidence for processing Isatis tinctoria L., a non-nutritional plant, 32–34,000 years ago
Laura Longo et al.
PLoS ONE, May 2025
Abstract:
Recovering evidence for the intentional use of plants in the Palaeolithic is challenging due to their perishable nature as, unlike chipped stone or bone artefacts, plant remains are rarely preserved. This has created a paradigm for the Palaeolithic in which plants seldom feature, resulting in a partial and skewed perspective; in fact, plants were as essential to human life then as they are today. Here, we combine morphological and spectroscopic analyses (µ-Raman, µ-FTIR) to provide robust multiscale physical and biomolecular evidence for the deliberate pounding and grinding of Isatis tinctoria L. leaves 34–32,000 years ago. The leaf epidermis fragments were found entrapped in the topography of the used surface of unmodified pebbles, in association with use-wear traces. Although their bitter taste renders them essentially inedible, the leaves have well-recognised medicinal properties and contain indigotin precursors, the chromophore responsible for the blue colour of woad, a plant-based dye that is insoluble in water. We used a stringent approach to contamination control and biomolecular analysis to provide evidence for a new perspective on human behaviour, and the applied technical and ecological knowledge that is likely to have prevailed in the Upper Palaeolithic. Whether this plant was used as a colourant, as medicine, or indeed for both remains unknown, but offers a new perspective on the fascinating possibilities of non-edible plant use.
