ABSTRACT The Cathedral of Saint Lawrence in Lugano, Switzerland is an important religious and historical site that contains both immovable and moveable works of art. Although the structure itself has changed, it retains many important wall paintings. In 1910, the cathedral underwent comprehensive restoration under the direction of Augusto Guidini and the painter Ernesto Rusca, including executing new paintings on undecorated surfaces, adding decorative features such as frames to some existing paintings, and retouching and filling losses to create a harmonious and coherent scheme in which all phases remained legible. By 2000, conservation issues were evident for all painted surfaces, including efflorescence, flaking paint and losses. From 2009 to 2017 another restoration project was carried out. The conservation of the wall paintings proved to be a complex process and two main aspects were important in informing decisions regarding methodology and treatments: the effects of moisture and climate, and the role of the unifying decorative scheme from the Guidini/Rusca intervention. The success of the recent project rested on prioritising the conservation needs of the paintings, considering the changes necessary to satisfy the religious and public function of the building, and wrestling with the historical, ethical, and material issues connected with the earlier intervention.

变化与连续性：瑞士圣劳伦斯大教堂壁画修复中的物质与伦理问题

摘要 瑞士卢加诺的圣劳伦斯大教堂是重要的宗教和历史遗址，包含不可移动和可移动的艺术作品。虽然结构本身发生了变化，但它保留了许多重要的壁画。1910年，大教堂在奥古斯托·圭迪尼和画家埃内斯托·鲁斯卡的指导下进行了全面修复，包括在未装饰的表面上进行新的绘画，在一些现有的画作上增加框架等装饰特征，修饰和填补损失，创造一个和谐连贯的所有阶段都保持清晰的方案。到 2000 年，所有涂漆表面都存在明显的保护问题，包括风化、油漆剥落和损失。从 2009 年到 2017 年，进行了另一个修复项目。事实证明，壁画的保护是一个复杂的过程，两个主要方面对有关方法和处理的决策很重要：水分和气候的影响，以及 Guidini/Rusca 干预中统一装饰方案的作用。最近项目的成功取决于优先考虑绘画的保护需求，考虑到满足建筑物的宗教和公共功能所需的变化，以及与早期干预相关的历史、伦理和材料问题的斗争。
