高光谱成像技术在中国古代书画分析中的应用研究综述

中国古代书画，因其年代久远，递藏情况复杂，多数屡经裁切割补、修复重装，故而有很多历史信息或被叠摞或被遮蔽，导致今人不能以肉眼直接观察而获得，而纸绢接补，墨迹、颜料、印鉴的残损也为书画研究者带来诸多悬而未决的问题。近年来，高光谱技术作为一种非侵入式的光谱成像技术，已逐步应用于各类彩绘文物中，该技术可为中国古代书画研究和保护提供更丰富的信息。本工作以文献调研为基础，简要介绍了高光谱成像的原理及技术特点，对高光谱技术在中国古代书画研究的实践进行总结，梳理了国内外研究者利用高光谱技术在书画、档案及相关彩绘文物的增强显示、物质识别、虚拟修复方面的应用案例，以期为相关研究者提供参考借鉴。     

Water and power in South Arabia: the excavation of “Monumental Building 1” (MB1) at Sumhuram (Sultanate of Oman)

The ancient port city of Sumhuram (Dhofar Governorate, Sultanate of Oman) has been the focus of over 20 years of research by the Italian Mission to Oman (IMTO), University of Pisa, in collaboration with the Office of the Adviser to His Majesty the Sultan for Cultural Affairs (Muscat-Salalah, Sultanate of Oman). Excavation has revealed most of the town layout, leading to the identification of several buildings, alleyways, squares and workshops, among which two massive buildings stand out, significantly named by the excavators as “Monumental Building” 1 and 2 (MB1 and MB2). This paper presents the results of the excavation inside MB1, characterised by the presence of the only well discovered within the city walls, which was previously interpreted alternatively as a palace or as a temple. The architectural development of the building, its distinctive features, the archaeological material discovered inside it, and its chronology will be discussed. These results highlight the absence of fitting parallels from other ancient South Arabian towns. Overall, it is clear that access to, management of, and control over the water supply of the town represented a key asset which justified the huge investment in workforce and building materials that is reflected in the monumental architecture of this edifice.     

河南焦作聂村商代晚期墓地人骨研究

通过对河南焦作聂村商代晚期遗址出土的人骨进行观察、测量和数据统计分析,结果表明,聂村商代晚期墓地所出人骨的死亡年龄主要集中在中年期,颅骨种族特征与古中原类型的殷墟中小墓(2)组最近似,成年男性居民平均身高为165.41厘米。在聂村商代晚期人骨上还发现筛状眶与多孔性骨肥厚、骨性关节炎等骨骼病理,两性在龋病患齿率上存在显著差异,女性明显高于男性。     

唐玉门关地望新探——基于历史文献与考古遗存互证

在实地调查的基础上,根据传世典籍和出土文献的记载,结合年代测定、考古发现和遥感影像资料,通过空间分析,作者认为唐玉门关和墨离军驻地应在河西走廊西段的常乐故城,即今瓜州县“六工古城”遗址。这里是丝绸之路的交通枢纽,是西域出入口的重要关卡,亦即北魏时期新开伊吾道的起首。唐代玉门关地处疏勒河和榆林河下游洪积冲积扇缘的古绿洲,地貌和水资源等地理环境因素是制约关城选址的基础条件,而政治、军事等人文地理因素则是决定玉门关时空变迁的关键。     

基于磁化率测量平遥古城古砖的烧制温度

古砖的烧制温度决定了其物理力学性质。本研究提出基于磁化率来确定古砖烧制温度的方法。通过对古砖重新加温,测量不同温度下古砖的磁化率,得到磁化率差值的平方-温度曲线图。图中第一个较大的偏差对应的横坐标即为古砖的烧制温度。利用上述方法测得实际烧制温度为700℃、800℃和900℃的黏土砖的烧制温度分别为690℃、810℃和870℃。二者误差较小,认为利用该方法确定砖的烧制温度可行。本研究利用该方法确定了平遥古城10块古砖的烧制温度,发现其烧制温度在650～690℃和850～870℃两个区间范围内。据此推测平遥古城古砖是以秸秆和木柴为燃料烧制而成。本研究实验结果可为古建筑修复和保护提供理论参考。     

The quest for a traditional style: architecture and heritage processes in a Pyrenean valley

In this article, I focus on the construction and restoration of houses in the Catalan Pyrenees, on their materiality, and specifically on the relationship between architectural and heritage processes that shapes them. I provide an analysis of how architectural forms, norms and regulations, as well as building aesthetics and materials, were transformed in the past decades following a parallel process of changes in the region. The aim is to explore the relationship between the built environment and the cultural and economic shift of the area in recent times. Drawing on extensive ethnographic research conducted in a valley of the Catalan Pyrenees, I show how the material culture, architecture and built environment evolved in close relationship to the spread of heritage discourses leading to a mutually constituting association that helped shape the elements of the new social realities.     

Conceptual Debts: Modern Architecture and Neo-Thomism in Postwar America

This article analyzes the formative role of medieval theology and aesthetics in the development of postwar American architecture by focusing on the architectural theory and practice of Mies van der Rohe and Jean Labatut, both of whom became actively interested in Neo-Thomism from the late 1940s. More specifically, a closer look at their reliance on the work of Jacques Maritain, the preeminent promotor of Neo-Thomism, sheds light on the transmission and circulation of old and new concepts within twentieth-century architectural theory. By revealing how Maritain’s ideas helped to codify the latter and thus exposed the premodern ideas at the heart of modern architecture, I argue that modernist aesthetics should be re-evaluated with regards to its definition of “the new” and its emphasis on the breakdown or mutation of premodern frames of reference.
