Characterisation and Conservation of Paintings on Walls and Sculpture from Nabataean Petra

1812年在约旦重新发现今天的联合国教科文组织世界遗产佩特拉后，现场考古研究发挥了非常重要的作用。大量的发现伴随着保护措施的需要。在本项目中，将在考古研究、化学研究和保护研究密切合作的框架内，示范开发检测、表征和保护墙面灰泥和雕塑上的古代绘画的方法。对于纳巴泰壁画的遗迹，计划进行广泛的调查和记录，其中包括使用便携式仪器对现场镀金壁画进行详细的考古研究。接下来将进行进一步的研究，以确定实验室中的改变机制。同样，计划对最近发现的大理石雕塑及其彩绘装饰进行更好的文件记录、化学特征和理解。其中一个重点也将放在镀金绘画上。为了采取必要的保护措施，将在现场进行大规模的环境监测，并将开发基于有机-无机聚合物的新保护材料。来自约旦文物局(DOA)和佩特拉考古公园(PAP)的专家将参与该项目。此外，还将为他们提供分析技术培训课程。

After the re-discovery of the today UNESCO World Heritage Site Petra in Jordan in 1812 archaeological research onsite plays a very important role. The large number of discoveries is accompanied by the need of conservation measures. In this project methods shall be exemplarily developed for the detection, characterisation, and conservation of ancient painting on wall plaster and sculpture in the frame of intense cooperation between archaeological research, chemical research and conservation research. For the remains of Nabataean wall paintings an extensive survey and documentation is planned, which includes a detailed archaeometric study of gilded wall paintings in situ with portable instruments. A further study to determine alteration mechanisms in laboratories will follow. Likewise a better documentation, chemical characterisation, and understanding of recently discovered marble sculptures and their painted decoration is planned. One focus will be on gilded paintings, as well. For required conservational measures a large environmental monitoring will be carried out on site and new conservation materials on the basis of organic-inorganic polymers will be developed. Specialists from the Department of Antiquity of Jordan (DoA) and Petra Archaeological Park (PAP) will take part in the project. In addition, they will be offered training courses on the analytical techniques.
