0. Hamelin once said that Descartes was a direct successor of the ancients, almost as if, with the exception of a few naturalists, there had been no philosophical thought between the ancients and Descartes. The refutation of this view seems to be the driving force in the philosophical development of Etienne Gilson. From his earliest research on Descartes, up to the present, Gilson has, in one way or another, attempted to point out both the validity of medieval philosophy and its historical influence on the moderns. Gilson's recent publication, History of Christian Philosophy in the Middle Ages,' must be seen within this broad framework. He attempts to show that there is a validly constituted system of thought called Christian Philosophy. This book is a comprehensive analysis of philosophical thought from the second century to the fifteenth century, from the Greek Apologists through Nicolas of Cusa. During this period we find that philosophical thought exiists only within a theological context. The Christians had the divinely inspired books of Holy Scripture; but in these canonical writings there are terms of Greek philosophical origin. C'hristian Philosophy is understood therefore as " the use made of philosophical notions by the Christian Writers " (iii). It was not that the nature of Revelation was such that it should be made philosophical. It was, rather, the particular dynamism of man as he attempted to support Revelation rationally. It is in this sense that Gilson understands the existence of a philosophy that takes its inspiration from the truths of Revelation. The theme of the volume is simply stated: " Every time educated Christians came in contact with Greek philosophical sources, there was a blossoming of theological and philosophical speculations " (540). The book starts with a discussion of the Greek Apologists. They, the first Fathers of the Church, directed their writings to a defense and explanation of their beliefs against the pagans. Since the first language of the Church was Greek, these men wrote in Greek, the language of philosophy; thereby began a dialogue between Christianity and philosophy. It is with the next period, entitled Early Christian Speculation, that we find a conscious use of Greek philosophical thought. Neoplatonism was used to explain the Christian Faith. Clement of Alexandria had even believed that God had guided the Greek philosophers. After this introductory section, we move on to the major part of the book. If one would permits such a classification-it is made with realization that it iIs only one perspective-there are three categories of philosopher: major, to which more than eighteen pages are devoted; intermediate, between eight and fifteen pages; and minor, less than six pages. In the category of major we have four philosophers: Avicenna (29 pp.), St. Albert (22), Roger Bacon (18), and St. Thomas (22). In the category of intermediate there are eleven: St. Augustine (11), Boethius (9), Scotus Erigena (9), St. Anselm (11), Abelard (9), Averroes (9), William of Auvergne (9),

Paleography is the study of ancient and historical handwriting, its key objectives include the dating of manuscripts and understanding the evolution of writing. Estimating when a document was written and tracing the development of scripts and writing styles can be aided by identifying the individual scribes who contributed to a medieval manuscript. Although digital technologies have made significant progress in this field, the general problem remains unsolved and continues to pose open challenges. ... We previously proposed an approach focused on identifying specific letters or abbreviations that characterize each writer. In that study, we considered the letter "a", as it was widely present on all pages of text and highly distinctive, according to the suggestions of expert paleographers. We used template matching techniques to detect the occurrences of the character "a" on each page and the convolutional neural network (CNN) to attribute each instance to the correct scribe. Moving from the interesting results achieved from this previous system and being aware of the limitations of the template matching technique, which requires an appropriate threshold to work, we decided to experiment in the same framework with the use of the YOLO object detection model to identify the scribe who contributed to the writing of different medieval books. We considered the fifth version of YOLO to implement the YOLO object detection model, which completely substituted the template matching and CNN used in the previous work. The experimental results demonstrate that YOLO effectively extracts a greater number of letters considered, leading to a more accurate second-stage classification. Furthermore, the YOLO confidence score provides a foundation for developing a system that applies a rejection threshold, enabling reliable writer identification even in unseen manuscripts.
Medieval slavery has received little attention relative to slavery in ancient Greece and Rome and in the early modern Atlantic world. This imbalance in the scholarship has led many to assume that slavery was of minor importance in the Middle Ages. In fact, the practice of slavery continued unabated across the globe throughout the medieval millennium. This volume – the final volume in The Cambridge World History of Slavery – covers the period between the fall of Rome and the rise of the transatlantic plantation complexes by assembling twenty-three original essays, written by scholars acknowledged as leaders in their respective fields. The volume demonstrates the continual and central presence of slavery in societies worldwide between 500 CE and 1420 CE. The essays analyze key concepts in the history of slavery, including gender, trade, empire, state formation and diplomacy, labor, childhood, social status and mobility, cultural attitudes, spectrums of dependency and coercion, and life histories of enslaved people.
Large Language Models (LLMs) are increasingly applied to medicine, yet their adoption is limited by concerns over reliability and safety. Existing evaluations either test factual medical knowledge in isolation or assess patient-level reasoning without verifying correctness, leaving a critical gap. We introduce MediEval, a benchmark that links MIMIC-IV electronic health records (EHRs) to a unified knowledge base built from UMLS and other biomedical vocabularies. MediEval generates diverse factual and counterfactual medical statements within real patient contexts, enabling systematic evaluation across a 4-quadrant framework that jointly considers knowledge grounding and contextual consistency. Using this framework, we identify critical failure modes, including hallucinated support and truth inversion, that current proprietary, open-source, and domain-specific LLMs frequently exhibit. To address these risks, we propose Counterfactual Risk-Aware Fine-tuning (CoRFu), a DPO-based method with an asymmetric penalty targeting unsafe confusions. CoRFu improves by +16.4 macro-F1 points over the base model and eliminates truth inversion errors, demonstrating both higher accuracy and substantially greater safety.
The article deals with the selected examples of the scene of Abraham’s hospitality in Eastern Christian and Serbian Medieval art. The paper analyzes the meaning of the scene and looks at the examples in the old refectory of the Monastery of St. Catherine on Sinai (fig. 1), in the chapel of King Dragutin Nemanjić in Đurđevi Stupovi near Ras (fig. 2), in the Church of the Mother of God in Dragaljevci near Sofia (fig. 3) and in the Church of St. Dimitrius in Boboševo (fig. 4) near Ćustendil.
As it illustrates one of the key moments of the Holy history, the scene of Abraham’s hospitality has been frequently depicted in art since the earliest times. Due to its significance, its has been attracting the attention of scholars since ancient times and has been widely studied in international and Serbian historiography in terms of iconography and meaning. Therefore, the article discusses selected examples of the scene of Abraham’s hospitality in Eastern Christian and Serbian Medieval art which are characterized by certain iconographic and conceptual peculiarities. Abraham’s hospitality is an important, ancient, very often depicted and multifaceted theme, and the teaching about it represents the fundamental dogma of Orthodoxy – in this scene the image of the Holy Trinity is symbolically recognized. The article examines the position of this scene in the painted programme of the mentioned monuments and the dependence of the symbolism of this scene on the position it occupies in the painted programme of the church. Depending on the context in which this event is depicted in art, it carries a different meaning, i.e. different nuances of meaning. Selected examples of the scene of Abraham’s hospitality are placed in a specific conceptual context through examining their appropriate programmatic and conceptual analogies and by taking into account the place of their depiction in the given monuments. In this sense, the article places special emphasis on the fresco of Abraham’s Hospitality in the Chapel of King Dragutin Nemanjić in the Đurđevi Stupovi Monastery.
This study examines the impact of historical text normalization on the classification of medieval charters, specifically focusing on document dating and locating. Using a data set of Middle High German charters from a digital archive, we evaluate various classifiers, including traditional and transformer-based models, with and without normalization. Our results indicate that the given normalization minimally improves locating tasks but reduces accuracy for dating, implying that original texts contain crucial features that normalization may obscure. We find that support vector machines and gradient boosting outperform other models, questioning the efficiency of transformers for this use case. Results suggest a selective approach to historical text normalization, emphasizing the significance of preserving some textual characteristics that are critical for classification tasks in document analysis.

The Latin language has received attention from the computational linguistics research community, which has built, over the years, several valuable resources, ranging from detailed annotated corpora to sophisticated tools for linguistic analysis. With the recent advent of large language models, researchers have also started developing models capable of generating vector representations of Latin texts. The performances of such models remain behind the ones for modern languages, given the disparity in available data. In this paper, we present the LiMe dataset, a corpus of 325 documents extracted from a series of medieval manuscripts called Libri sententiarum potestatis Mediolani, and thoroughly annotated by experts, in order to be employed for masked language model, as well as supervised natural language processing tasks.

The island of Sardinia has been of particular interest to geneticists for decades. The current model for Sardinia’s genetic history describes the island as harboring a founder population that was established largely from the Neolithic peoples of southern Europe and remained isolated from later Bronze Age expansions on the mainland. To evaluate this model, we generate genome-wide ancient DNA data for 70 individuals from 21 Sardinian archaeological sites spanning the Middle Neolithic through the Medieval period. The earliest individuals show a strong affinity to western Mediterranean Neolithic populations, followed by an extended period of genetic continuity on the island through the Nuragic period (second millennium BCE). Beginning with individuals from Phoenician/Punic sites (first millennium BCE), we observe spatially-varying signals of admixture with sources principally from the eastern and northern Mediterranean. Overall, our analysis sheds light on the genetic history of Sardinia, revealing how relationships to mainland populations shifted over time. Ancient DNA analysis of early European farmers has found a high level of genetic affinity with present-day Sardinians. Here, the authors generate genome-wide capture data for 70 individuals from Sardinia spanning the Middle Neolithic to Medieval period to reveal relationships with mainland European populations shifting over time.
Abstract Climate reconstructions for the Common Era are compromised by the paucity of annually-resolved and absolutely-dated proxy records prior to medieval times. Where reconstructions are based on combinations of different climate archive types (of varying spatiotemporal resolution, dating uncertainty, record length and predictive skill), it is challenging to estimate past amplitude ranges, disentangle the relative roles of natural and anthropogenic forcing, or probe deeper interrelationships between climate variability and human history. Here, we compile and analyse updated versions of all the existing summer temperature sensitive tree-ring width chronologies from the Northern Hemisphere that span the entire Common Era. We apply a novel ensemble approach to reconstruct extra-tropical summer temperatures from 1 to 2010 CE, and calculate uncertainties at continental to hemispheric scales. Peak warming in the 280s, 990s and 1020s, when volcanic forcing was low, was comparable to modern conditions until 2010 CE. The lowest June–August temperature anomaly in 536 not only marks the beginning of the coldest decade, but also defines the onset of the Late Antique Little Ice Age (LALIA). While prolonged warmth during Roman and medieval times roughly coincides with the tendency towards societal prosperity across much of the North Atlantic/European sector and East Asia, major episodes of volcanically-forced summer cooling often presaged widespread famines, plague outbreaks and political upheavals. Our study reveals a larger amplitude of spatially synchronized summer temperature variation during the first millennium of the Common Era than previously recognised.
The sculpted decoration on the chancel slabs of the church of Santa Maria Assunta in Aquileia depicts a harmonious universe that channels matter in the process of transformation, like the spiritualization of the caro through the sacraments. The various elements that make up this universe are linked together to emphasize the coherence of Creation. In this constructed space, the boundaries between plant, mineral, animal and ornamental dissolve and merge, as does the distinction between known and imaginary animals. On one of the chancel slabs, two creatures are depicted with characteristics of terrestrial, celestial and aquatic animal species. They drink from the Fountain-Tree of Life, making a link between here below and hereafter and bringing hope of salvation. Facing each other, they oppose each other to obstruct the passage of the faithful, reinforcing the separating function of the chancel, marking the frontier between the nave and the choir, between the laity and the clerics. Presented on a vertical support facing the faithful, these composite beings help to bring man closer to God, inviting him to be one with Christ through communion, to give himself, body and soul, to the Church. Based on order, diversity and moderation, this rhythmic pictorial universe invites us to go beyond the limits of the visible, the sensible, the material, to move away from the opposition of similarity/dissimilarity and to advance towards the invisible, the intelligible and the immaterial.

Medieval paper, a handmade product, is made with a mould which leaves an indelible imprint on the sheet of paper. This imprint includes chain lines, laid lines and watermarks which are often visible on the sheet. Extracting these features allows the identification of paper stock and gives information about chronology, localisation and movement of books and people. Most computational work for feature extraction of paper analysis has so far focused on radiography or transmitted light images. While these imaging methods provide clear visualisation for the features of interest, they are expensive and time consuming in their acquisition and not feasible for smaller institutions. However, reflected light images of medieval paper manuscripts are abundant and possibly cheaper in their acquisition. In this paper, we propose algorithms to detect and extract the laid and chain lines from reflected light images. We tackle the main drawback of reflected light images, that is, the low contrast attenuation of lines and intensity jumps due to noise and degradation, by employing the spectral total variation decomposition and develop methods for subsequent line extraction. Our results clearly demonstrate the feasibility of using reflected light images in paper analysis. This work enables the feature extraction for paper manuscripts that have otherwise not been analysed due to a lack of appropriate images. We also open the door for paper stock identification at scale.
This article evaluates 165 studies from various disciplines, published between 2000 and 2019, which in different ways link past climate variability and change to human history in medieval and early modern Europe (here, c. 700–1815 CE). Within this review, we focus on the identification and interpretation of causal links between changes in climate and in human societies. A revised climate–society impact order model of historical climate–society interactions is presented and applied to structure the findings of the past 20 years' scholarship. Despite considerable progress in research about past climate–society relations, partly expedited by new palaeoclimate data, we identify limitations to knowledge, including geographical biases, a disproportional attention to extremely cold periods, and a focus on crises. Furthermore, recent scholarship shows that the limitations with particular disciplinary approaches can be successfully overcome through interdisciplinary collaborations. We conclude the article by proposing recommendations for future directions of research in the climatic change–human history nexus.
The distribution of the black rat (Rattus rattus) has been heavily influenced by its association with humans. The dispersal history of this non-native commensal rodent across Europe, however, remains poorly understood, and different introductions may have occurred during the Roman and medieval periods. Here, in order to reconstruct the population history of European black rats, we first generate a de novo genome assembly of the black rat. We then sequence 67 ancient and three modern black rat mitogenomes, and 36 ancient and three modern nuclear genomes from archaeological sites spanning the 1st-17th centuries CE in Europe and North Africa. Analyses of our newly reported sequences, together with published mitochondrial DNA sequences, confirm that black rats were introduced into the Mediterranean and Europe from Southwest Asia. Genomic analyses of the ancient rats reveal a population turnover in temperate Europe between the 6th and 10th centuries CE, coincident with an archaeologically attested decline in the black rat population. The near disappearance and re-emergence of black rats in Europe may have been the result of the breakdown of the Roman Empire, the First Plague Pandemic, and/or post-Roman climatic cooling. ‘Archaeogenetic analysis of black rat remains reveals that this species was introduced into temperate Europe twice, in the Roman and medieval periods. This population turnover was likely associated with multiple historical and environmental factors.’
The appearance of the local centres of glazed ware production in the Palaiologean Period allowed the development of local schools of parade table ware. In the Crimean Peninsula, the local production centres were active in the fourteenth and fifteenth centuries. In the Genoese castle of Cembalo, there were glazed ware workshops from the second half of the fourteenth to the third quarter of the fifteenth century. Along with the manufacture of various forms of original pottery, the artisans of these workshops copied the ornamental compositions which were popular in the Mediterranean area. This article addresses the vessels attributed to the so-called “imitations” or “counterfeits”, which reproduced the samples of the Byzantine glazed pottery of the group of Elaborate Incised Ware, so widespread in the region. Among these vessels, there possibly were the pieces produced in the same workshop or by the same artisan: small handleless cups with small flaring ring-base, bowls, and tureens or dishes with the so-called “aslant” ring-base typical of the Byzantine pottery from the thirteenth and fourteenth centuries. The finds in question testify to the popularity of the Byzantine Elaborate Incised Ware in the Northern Black Sea Area, and the Genoese castle of Cembalo in particular, in the fourteenth and early fifteenth centuries.

Hansen’s disease (leprosy), widespread in medieval Europe, is today mainly prevalent in tropical and subtropical regions with around 200,000 new cases reported annually. Despite its long history and appearance in historical records, its origins and past dissemination patterns are still widely unknown. Applying ancient DNA approaches to its major causative agent, Mycobacterium leprae, can significantly improve our understanding of the disease’s complex history. Previous studies have identified a high genetic continuity of the pathogen over the last 1500 years and the existence of at least four M. leprae lineages in some parts of Europe since the Early Medieval period. Here, we reconstructed 19 ancient M. leprae genomes to further investigate M. leprae’s genetic variation in Europe, with a dedicated focus on bacterial genomes from previously unstudied regions (Belarus, Iberia, Russia, Scotland), from multiple sites in a single region (Cambridgeshire, England), and from two Iberian leprosaria. Overall, our data confirm the existence of similar phylogeographic patterns across Europe, including high diversity in leprosaria. Further, we identified a new genotype in Belarus. By doubling the number of complete ancient M. leprae genomes, our results improve our knowledge of the past phylogeography of M. leprae and reveal a particularly high M. leprae diversity in European medieval leprosaria. Our findings allow us to detect similar patterns of strain diversity across Europe with branch 3 as the most common branch and the leprosaria as centers for high diversity. The higher resolution of our phylogeny tree also refined our understanding of the interspecies transfer between red squirrels and humans pointing to a late antique/early medieval transmission. Furthermore, with our new estimates on the past population diversity of M. leprae, we gained first insights into the disease’s global history in relation to major historic events such as the Roman expansion or the beginning of the regular transatlantic long distance trade. In summary, our findings highlight how studying ancient M. leprae genomes worldwide improves our understanding of leprosy’s global history and can contribute to current models of M. leprae’s worldwide dissemination, including interspecies transmissions.
Studying ancient DNA allows us to retrace the evolutionary history of human pathogens, such as Mycobacterium leprae, the main causative agent of leprosy. Leprosy is one of the oldest recorded and most stigmatizing diseases in human history. The disease was prevalent in Europe until the 16th century and is still endemic in many countries with over 200,000 new cases reported annually. Previous worldwide studies on modern and European medieval M. leprae genomes revealed that they cluster into several distinct branches of which two were present in medieval Northwestern Europe. In this study, we analyzed 10 new medieval M. leprae genomes including the so far oldest M. leprae genome from one of the earliest known cases of leprosy in the United Kingdom—a skeleton from the Great Chesterford cemetery with a calibrated age of 415–545 C.E. This dataset provides a genetic time transect of M. leprae diversity in Europe over the past 1500 years. We find M. leprae strains from four distinct branches to be present in the Early Medieval Period, and strains from three different branches were detected within a single cemetery from the High Medieval Period. Altogether these findings suggest a higher genetic diversity of M. leprae strains in medieval Europe at various time points than previously assumed. The resulting more complex picture of the past phylogeography of leprosy in Europe impacts current phylogeographical models of M. leprae dissemination. It suggests alternative models for the past spread of leprosy such as a wide spread prevalence of strains from different branches in Eurasia already in Antiquity or maybe even an origin in Western Eurasia. Furthermore, these results highlight how studying ancient M. leprae strains improves understanding the history of leprosy worldwide.
