The Liuwan burial complex is the largest known prehistoric clan-based cemetery in the upper Yellow River region, making its preservation vital for Chinese cultural heritage and sustainable local development. To address threats from unregulated agricultural activities and illegal looting, this study proposes a non-invasive preventive protection approach. Surface-visible tombs were identified using low-altitude UAV imagery and deep learning models (YOLOv8n, YOLOv5n, RT-DETR-l, and Hyper-YOLO). By incorporating environmental factors such as elevation, slope, aspect, distance to water, Topographic Wetness Index, and Topographic Position Index, potential tomb distributions were modeled on the Biomod2 platform and key environmental drivers were analyzed. Hyper-YOLO achieved the highest identification accuracy (94.4%). The optimal model, EMwmean (TSS = 0.492, AUC = 0.798), showed that high-potential tomb areas are mainly concentrated in the central region, with tombs preferring elevations of 1964–1978 m, south-facing slopes, and slopes of 13.14–19.19°. This study demonstrates the feasibility of using deep learning to identify surface-visible tombs and predict their potential distributions based on environmental characteristics, thereby providing priority references for heritage protection in Liuwan rather than a definitive inventory of all subsurface remains or cultural phases.

As part of a fundamental and comprehensive monitoring and conservation of the tomb of Emperor Otto the Great in the cathedral of Magdeburg, the question of the provenance of the marble cover slab of the sarcophagus was investigated. Within the restoration activities, two samples of the slab were taken for scientific provenance analyses, one sample of the white marble and another of the irregular grey bands. The following investigations were used for this purpose: analysis of the stable isotopes of O and C, and chemical analysis of a large number of trace elements, resulting in a large number of variables. For the simultaneous evaluation of these numerical results, statistical multivariate analysis was used for comparing the results with our database of approximately 7000 samples from ancient marble quarries and the data being referenced in this investigation are published and listed here. The results obtained clearly identify the quarries of Prokonnesos in the Sea of Marmara as the most probable source of the examined slab. This is in perfect agreement with petrographic analyses carried out on these samples. Full article

This paper addresses the important issue of the proper management and protection of subterranean monuments. It concerns the analysis and decoding of the microclimate that is created in heritage structures, which are structures located beneath the soil or carved into rock. The aim of this study is to understand the hygrothermal processes occurring in the mass of underground structural elements, such as evaporation, condensation, water content, and heat fluxes, based on the principles of building physics. The methodology used is the following: a systematic literature review on the topic, an overview of the factors affecting the microclimate, the assessment methodology, and the simulation tools used to decode and evaluate microclimate in subterranean heritage structures; a discussion of the current gaps; and finally, a proposal for future directions for research. A review of the literature reveals that researchers worldwide have employed similar methodologies to approach this complex issue. Recordings and analyses of the microclimate inside underground monuments lead to decision-making and the formulation of actions for optimal preservation. Due to the large number of parameters involved in microclimate analysis, computer software for numerical simulation has been used in many cases. Following the review of the relevant literature in the field of study, a critical discussion concludes by proposing directions for future research on this important topic. Basic results of this research identify current gaps, problems, and limitations. These include technical and practical issues or gaps concerning lack of data for material properties and weather conditions. Another significant limitation arises from the complexity of physical interactions, as well as from the human factor, which involves the proper use of the simulation program and the correct interpretation of the calculation results. This study demonstrates that the microclimate of subterranean heritage structures is the result of complex interactions between climate, geology, architectural design, material properties, and human use. Across different geographical and cultural contexts, subterranean monuments exhibit distinct microclimatic behaviors. The comparative analysis of case studies highlights that while subterranean environments generally benefit from thermal stability, they remain highly vulnerable to moisture dynamics, ventilation changes, and external climatic coupling. Hence, there is a necessity for context-specific approaches rather than generalized conservation solutions. Decoding subterranean microclimates requires a multidisciplinary framework that combines environmental monitoring, material indicators, architectural analysis, and numerical modeling. Full article

The identification of dyes in ancient textiles is crucial for provenance research and scientific conservation. However, the extremely significant value of these cultural relics necessitates the use of non-destructive analytical techniques. To establish a non-destructive, in-situ, accurate, and rapid method for identifying natural dyes in ancient silk fabric samples, we employed desorption electrospray ionization high-resolution mass-spectrometry imaging (DESI-MSI). By optimizing key instrumental parameters—including sample pretreatment method, DESI spray solvent composition, and DESI heated transfer line (HTL) temperature—we determined the optimal mass-spectrometry imaging conditions. The optimal conditions for achieving the highest mass-spectrometry ion peak signal intensity and the best imaging quality were as follows: employing sample pretreatment using double-sided adhesive tape; a spray solvent composed of methanol (100%, v/v) with 0.1% formic acid and 0.1 μg/mL of leucine enkephalin; and an HTL temperature of 400 °C. The characteristic compound in the G42 silk fabric sample was successfully separated. Based on the characteristic mass-to-charge ratio of the major component, the compound was preliminarily identified as berberine. This result was further verified by tandem mass-spectrometry imaging and tandem mass spectra and finally confirmed by comparison with the mass spectrum of a reference standard. Consequently, the source of the dye in the sample was determined to be amur cork tree. The experiments confirmed the applicability and accuracy of the DESI-MSI method for the non-destructive analysis of precious textiles. This work underscores the urgent need to use such non-destructive techniques to provide technical support for the identification of high-value, inaccessible, or fragile silk artifacts and guide the historical tracing and preservation of these cultural relics.

Cultural heritage sites in arid regions are often underestimated in terms of flood risk; however, the increasing frequency and intensity of extreme precipitation events under climate change have significantly amplified threats to these fragile environments. Taking the Xixia Imperial Tombs in China as a case study, this research investigates strategies for flood hazard prevention and control for cultural heritage in arid areas. By situating the study within the broader context of climate change and global heritage conservation, the paper examines the impacts of flooding on heritage sites and the historical evolution of flood control measures. It further integrates an analysis of the site’s geographical characteristics, traditional flood management structures, and contemporary conservation practices. The study systematically elucidates the compound risks of “drought–desertification–sudden flooding” faced by cultural heritage in arid landscapes. The findings suggest that heritage protection should transition from reactive, post-disaster restoration toward proactive preventive conservation. This shift requires the integration of both engineering and non-engineering measures, supported by technology-based systems such as environmental monitoring and early warning platforms, to establish a comprehensive risk management framework. The research highlights that overcoming the prevailing misconception that “arid regions are free from flood risks,” embedding heritage flood management into regional planning, and ensuring legal, financial, and interdisciplinary cooperation are essential for the long-term safeguarding of cultural heritage in arid environments. This study offers practical insights and a transferable reference for the protection of heritage sites in similar climatic and geographical contexts worldwide. Full article

This article studies the unique funerary decorative and architectural programs of the Foyemiaowan tombs in Dunhuang, dating to the third and fourth centuries CE. While Dunhuang is known for its later Buddhist grottoes, its sophisticated pre-Buddhist religious landscape remains understudied. This article focuses on the elaborate screen walls constructed of painted pictorial bricks, which represent the celestial realm designed to visualize the soul’s transcendence to heaven. Based on iconographic analysis, this study discusses the highlighted decorative design of screen wall at Foyemiaowan and explains the different artistic logics behind the lavish exterior decoration of Foyemiaowan vis-à-vis the interior-focused programs of neighboring sites like Xincheng in Jiayuguan. This study situates visual and material symbols in the distinct arrangement of the whole tomb space, which together reflect local adoption and innovation of Central Plain traditions in Early Medieval Dunhuang.

The Xi’an Beilin Museum preserves a large collection of archeological photographic negatives and films dating from the 1950s to the early 1980s. These images document significant archeological discoveries, including Tang dynasty imperial tomb murals, the excavation of the terracotta warriors, and various historical grottoes and stone carvings. As unique visual records of cultural heritage, these materials provide valuable references for studying environmental deterioration processes and for guiding conservation and restoration practices. However, long-term storage under uncontrolled environmental conditions has resulted in severe degradation of the negatives, including mold contamination, emulsion layer powdering, deformation, and partial detachment. Among these deterioration phenomena, microbial growth is particularly destructive because fungal hyphae cause light scattering and image obscuration, preventing scanning and digital archiving. In this study, mold species present on the negatives were isolated and identified using morphological observation and ITS rDNA sequence analysis. Based on the characteristics of the microbial contamination, targeted removal and restoration treatments were applied to recover the original image information. Furthermore, preventive protection strategies were implemented through the development of antifungal storage materials and protective containers. The results establish an integrated conservation approach combining microbial identification, restoration treatment, risk elimination, and preventive protection, providing a scientific basis for the long-term preservation of historical photographic archives.

One of the most famous and frequently analysed descriptions in literary and art history is undoubtedly Dostoevsky’s ekphrasis of Holbein’s painting The Dead Christ in the Tomb in his novel The Idiot (Part III. Chapter 6). The painting itself sparked a series of theological and aesthetic controversies with its unusual, non-canonical iconography depicting of the Passion of Christ. Most art historical analyses do not ignore the ekphrasis of that picture in The Idiot. In this study, we proceed from the premise that the “reading of the painting” leads to different results from the point of view of three main characters of the novel: Rogozhin, Myshkin, and Ippolit. Our goal is to prove that ekphrasis is an inseparable part of a speech act—not an objective description, but intentional speech. Therefore, it cannot be interpreted without understanding the speaker’s intention or the character’s situation. This explains the strong distortions and misreading in the ekphrasis. We can capture the meaning reconstructed in the character’s speech through the motifs of copy, epigonism, duplication and misquotation. Ippolit, the subiectum of ekphrasis, proves to be a truly “bad reader,” and his reading becomes devastating in the world of the novel insofar as it anticipates the destruction expressed in the motifs of the Apocalypse. In addition, we also reveal that there is a hidden intention behind Ippolit’s reading, which we can grasp by examining the signs in the text (metaphorical meaning). The most important motifs of ekphrasis (e.g., nature, the number six, actuality, darkness–light) weave through the entire text of the novel and are incorporated into the process of text production and meaning creation.

This study analyses the funerary practices in hypogea (rock-cut tombs) of the Middle Bronze Age in southern Portugal with the aim of deepening our understanding of Bronze Age funerary rituals in southwestern Iberia. A total of 57 hypogea from seven archaeological sites were examined. The study followed an interdisciplinary approach integrating data from biological anthropology and archaeology, articulating chronology, osteological analysis, funerary architecture, and material culture. The hypogea date to the first half of the 2nd millennium BCE, corresponding to the regional Middle Bronze Age. Of the 95 individuals analysed, 82% were adults; females represented 34% and males 21% of the total sample. The hypogea present several architectural typologies, with entrances oriented towards southeast (30%), northeast (23%), southwest (22%), and northwest (22%), possibly related to moments of the solar cycle. Burials were single (54%), double (17%), or multiple (11%), with 68% primary inhumations and 32% secondary inhumations, reflecting the re-use of funerary spaces. Grave goods, present in 57% of the cases, were more frequent and diversified among women, including ceramic vessels (79%) and metal awls (61%). Like male individuals, women were also associated with weapons, suggesting an elevated social status for both sexes. Full article

The development of digital technology offers unprecedented opportunities in the documentation, conservation, and interpretation of cultural heritage. Due to its high precision, efficiency, and visualization, this technology provides innovative ways for people to interact with heritage sites. However, its dramatic development introduces several problems, including systematic deficiencies in high-precision data acquisition, difficulties in effectively integrating multi-source heterogeneous data, and an inability to reconstruct context during the digital restoration of heritage. Thus, this research proposes a framework of digital re-contextualization, reintegrating the lost physical space, visual information, and mental experience into a coherent whole through triangulation comparison, interpretive restoration, and experiential virtual reconstruction. Taking the Dingjiazha M5 Muraled Tomb as a case study, this article details how this framework was applied to systematically consolidate the archaeological literature and material-sourced spatial data to construct a reliable and verifiable digital replica of the in situ heritage site. This framework shifts the focus from mere data documentation to knowledge production and experiential reconstruction, ensuring the scientific integrity of the restoration and allowing more members of the public to access the heritage site. It also demonstrates how lost historical spaces can be reborn in the digital realm in a way that is both responsible and rich with interpretive depth. Full article

Archaeological reports show that about 70% of Han dynasty pictorial stone sites feature historical figures, revealing a significant yet understudied aspect of tomb ritual practice (muji yishi). This study examines how these depictions may reflect ritual characteristics and their relationship to temple ritual practice (miaoji yishi). From the Qin to Han period (221 BCE–220 CE), tomb and temple rituals increasingly converged; temple rituals were sometimes performed by tombs, and the imagery incorporated cosmological models alongside representations of daily life, including clothing, diet, dwellings, and mobility. The historical figures depicted can be grouped into three categories: emperors and sages, loyal ministers and righteous heroes, and filial sons and chaste women. These figures were closely associated with ideals of transcendence and immortality, suggesting a ritual framework that connected temple and tomb practices, with emperors and sages appearing most frequently, accounting for about 80% of the depictions. Notably, these images occur predominantly in commoners’ tombs (approximately 95%), where fewer social restrictions may have allowed greater creative freedom. While research on tomb ritual practices has traditionally relied on textual sources, the present study emphasizes archaeological evidence, offering an analytical perspective on the relationship between temple and tomb rituals in Han funeral art and highlighting their potential role in shaping Han ritual logic and religious expression.

According to our investigation carried out in July 2023, the wood of the Western Han Dynasty Dingtao M2 Tomb, stored in the preservation room, exhibited signs of microbial degradation. Our metagenomic analysis first revealed Penicillium as the dominant genus on the end of the wrapped wood. Furthermore, functional annotations demonstrated that the resident microbial community possessed cellulolytic and ligninolytic capabilities. Targeted metabolomic analysis evaluated the degradation capacity of Penicillium charlesii DTP_1, a strain isolated from the wrapped wood. We hypothesize that DTP_1 provides an acidic microenvironment via the production of organic acids; the functional microbial community then decomposes lignin into small metabolites via enzymatic action, and these products are then utilized by the microbial community, including DTP_1. Finally, we verified that liquid cinnamaldehyde and volatile gaseous allicin and carvacrol exhibit better inhibitory efficacy. Nevertheless, further optimization of plant-derived agents and application methods are still required. This study proposes a putative mechanism underlying the degradation of the Dingtao M2 Tomb wood by the microbial community, thereby providing theoretical support for the conservation of wooden cultural heritage and relics.

Archaeological sites characterized by the coexistence of extensive above-ground terrain and hypogeum structures present major challenges for accurate and comprehensive geospatial documentation. Conventional survey approaches—such as static terrestrial laser scanning (TLS), total-station measurements, and aerial photogrammetry—often suffer from operational constraints, particularly in the presence of narrow underground spaces, low or absent illumination, harsh environmental conditions, and restrictions on UAV deployment. Additional complexity arises when both surface and subterranean elements must be consistently georeferenced to a common global reference system, especially where establishing a traditional topographic–geodetic control network is impractical. Within the framework of the EIMAWA Egyptian–Italian Mission conducted by the University of Milano since 2018, the Geomatics group of the University of Bologna designed and implemented a multi-scale multi-technique 3D documentation workflow, with a prominent role assumed by Simultaneous Localization and Mapping (SLAM) mobile laser scanning. The approach was supported by GNSS measurements providing centimetric accuracy. SLAM was employed to document both the surface necropolis and multiple hypogeal tombs, enabling rapid acquisition of dense three-dimensional data in environments where traditional techniques are limited. All datasets were integrated within a unified reference system, resulting in a coherent, multi-layered spatial dataset representing both landscape and underground spaces. The results demonstrate that SLAM can produce dense point clouds that document at few-centimetric level accuracy and continuously both above- and below-ground contexts. Quantitative analyses of the co-registration and mutual alignment of multiple SLAM datasets confirm a high degree of internal consistency, further enhanced through post-processing refinement. Overall, the experience indicates that this solution represents a practical and reliable technique for complex archaeological surveying. Full article

The TaiLing Mausoleum in Western Qing Tombs has great aesthetic value and a rich history. In this study, we conducted an analysis of the materials used in the architectural polychrome paintings of the TaiLing Mausoleum. Optical microscopy (OM), portable X-ray fluorescence (p-XRF), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM–EDX), micro-Raman spectroscopy (μ-RS), and X-ray diffraction (XRD) were used to analyze the paintings of Long’en Gate in TaiLing Mausoleum. The results indicate that the main minerals in the ground layer are quartz, augite, feldspars and illite. The gilding materials employed gold leaf. The red pigment is hematite, and the black pigment is carbon black. The green pigment is emerald green with barium sulfate as an extender. The blue pigments are smalt and synthetic ultramarine. In some areas, emerald green is observed overlaying smalt, suggesting that the paintings at Long’en Gate underwent overlay restoration or repainting from the late Qing Dynasty to modern times. These results can support future conservation of the polychrome paintings at the TaiLing Mausoleum. Full article

Against the backdrop of a gradual shift in the focus of cultural heritage (CH) conservation and utilization toward the integrated system formed by CH and its surrounding environment as well as regional systems, research on the coordinated protection of nature and culture to promote regional high-quality development has become a new trend. However, systematic summaries of the spatial–temporal distribution of CH in cross-regional typical geomorphic units at the river basin scale and their correlation with the natural environment remain insufficient. This study takes 387 Cultural Relics Protection Units in the Three Gorges of the Yangtze River (the Three Gorges region) as the research objects, utilizing GIS spatial analysis technology to examine the impact of the natural environment on CH across different periods and types. The theory of time-depth is introduced to reveal the layering mechanisms and underlying cultural logics. Coupled with the Minimum Cumulative Resistance (MCR) model, this study constructs a cultural corridor network and proposes spatial planning strategies. The findings are as follows: (1) The absolute core area for the distribution of CH across all periods remains the gentle slope zone near the river, characterized by elevations below 500 m, slopes within 25°, and distances from water systems within 1 km. However, the adaptive scope exhibits a diachronic evolution from core accumulation to peripheral expansion. (2) Different types of CH exhibited distinct natural adaptation strategies and vertical accumulation. Settlement Sites in the Before Qin Dynasty Period formed the foundational layer of survival rationality, while Ordinary Tombs in the Qin–Yuan Dynasty Period reinforced sedentism. Ancient Architecture in the Ming–Qing Dynasty Period underwent a transformation from “adapting to nature” to “reconstructing nature” as a product of environmental construction. Modern and Contemporary Significant Historical Sites and Representative Buildings in the After Qing Dynasty Period are characterized by a ruptured insertion on steep slopes, inscribing revolutionary memory onto space. The main stream of the Yangtze River serves as the core area of continuous deposition, while the extremely steep slopes form a distinctive stratigraphic accumulation of precipitous terrain. (3) Based on these distribution patterns, the study further proposes a spatial framework for CH called “One Corridor, Three Wings.” This framework uses the main stream of the Yangtze River as the spatial–temporal axis, linking the four core overlapping nodes of Fengjie, Wushan, Badong, and Xiling, supplemented by three secondary cultural clusters of the red heritage sites in southern Badong, the ancient town along the Daning River in Wushan, and the fortress sites in the Xiling–Yiling area. This research not only reveals the evolutionary path of CH in the Three Gorges region, but also provides a scientific basis for the systematic conservation and differentiated utilization of regional CH. Furthermore, it serves as a planning foundation and strategic reference for planning the Yangtze River National Cultural Park, as well as for the integrated preservation and utilization of river basin CH and linear CH with the aim of coordinated natural and cultural conservation.
