一种油画颜料层裂纹的修复技术分析

油画颜料层裂纹是一种常见的病害类型,严重的裂纹会影响作品的视觉效果。裂纹修复所采取的措施应以缓解病害,延续寿命为目标,避免不当修复对其文物价值的改变。本研究通过红外光谱和便携式X荧光能谱分析,初步确定了裂纹产生的原因与材料技法和机械作用力有关,长期的温湿度波动则是最终形成老化裂纹的重要因素。对两类常见的裂纹加固方法比较后得出结论,色蜡改变了原画的光泽度和肌理层,动物胶调碳酸钙更适宜作为裂纹的填补材料。观察修复后的油画保存状况,发现经过修复的颜料层仍存在继续劣化的风险,必须维持保存环境的相对稳定,方可延长修复周期。     

War widows and revenge in Restoration England

This article examines petitions submitted by royalist widows to the House of Lords during the first few months of the Restoration. The husbands of these women had been tried and executed for treason during the 1640s and 1650s for their perceived loyalty to the royalist cause, prompting their spouses to demand retribution against their judges and jurors. As the Convention Parliament deliberated over the Act of Indemnity during the summer of 1660, these aggrieved widows were presented with an opportunity to ensure that the men they held responsible for their husband’s deaths were brought to account. By assessing the petitioning strategies adopted by these women and the government’s responses to their demands, the article throws light on a group of war widows who have received little scholarly attention. It is argued that whilst these women were largely unsuccessful, their efforts represent a significant aspect of female activism during the seventeenth century.     

Financial policies in the Papal States, 1790s–1848: a comparative study of Napoleonic Europe

This article discusses the financial policies of the Papal States from the late eighteenth to the mid-nineteenth century in relation to the rest of Europe, and especially Italy. Its crucial starting point is the Napoleonic economic reforms, which had important and often lasting effects throughout its former empire. French reliance on debt reduction and heavy though equitable taxation improved the financial conditions of most European lands even as they convulsed from the protracted wars. The economic austerity prior to 1814 forced post-Napoleonic Europe to make decisions on the degree of continuity on these two financial fronts. Political instability beginning in the 1820s for some, and the early 1830s and late 1840s for the rest, upset the rather tenuous financial position that most lands found themselves in. For the Papal States, the Napoleonic period improved its financial position to the detriment of ecclesiastical institutions. The period also revealed the inherent flaws in its financial system, necessitating a decentralized approach to the restoration, relying on individual (or institutional) initiatives and large foreign loans, in lieu of overarching policies. By the 1850s, a further lack of financial control induced the renewal of Peter’s Pence.     

浙江省平湖庄桥坟遗址出土石犁的保护修复

浙江平湖庄桥坟遗址出土的石犁是史前考古的新发现,属于痕迹文物。出土时木构件痕迹饱水,为暗褐色、开裂严重、整体呈腐蚀状,非常脆弱。针对器物的保存状况,因地制宜地制定一系列保护方法:木构件痕迹的脱水保护、底托的加固制作、木构件粘贴复原等,使文物得以长期保存。     

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。     

Balancing and Limiting Episcopal Power: Bishop Thomas Barlow’s Use of Common Law in Disputes with Arminian Anglican Clerics

Thomas Barlow was a Reformed theologian simultaneously fighting on three fronts against Catholic, Dissenting Protestant and Arminian Anglican opponents. The first two of these groups threatened the Church of England from the outside, while the last group was transforming Anglican doctrine through its domination of the most important posts in the episcopal hierarchy. Barlow could not argue directly against the power of bishops without assisting the external opponents, yet he had to find a way to prevent other bishops from interfering in his continued support for Reformed theology. In order to reduce their power within the Church of England, Barlow had to look outside the institution for ways to limit his superior’s power. This essay examines two arguments in which Barlow ventured into polemics about the secular law of England in an effort to maintain limits on his Anglican opponents’ exercise of power.     

清代早期四合如意云寸蟒纹织金妆花缎的结构分析与保护修复

受北京艺术博物馆的委托,对两件香色地四合如意云寸蟒纹织金妆花缎进行保护修复。两件妆花织物质地柔软、组织结构紧凑、纹样细腻、设色庄重。但经长期自然和人为因素的影响,织物多处破损、开裂、脱丝、破洞、污渍等,圆金和片金纹纬上的金片大量脱落,整体污染较为严重,质地脆弱,无法研究和展出。本文通过研究妆花所承载的历史文化信息、综合织物的质地、组织结构、纹样形态、设色特征等诸多因素,将其定为清早期织物。应用三维视频显微镜和电子丝绸尺软件对织物组织结构、破损程度进行了分析。在此基础上,制定了保护修复工作目标和方案。修复后的两件织物基本恢复了原貌,效果较好,可以作为研究中国丝织品的实物根据。
