Organisationseinheit der BAM
One of the most important collections of manuscripts and wall paintings from sites of the northern Silk Road, discovered at the beginning of the 20thC, are deposited in Berlin. The fragments represent a broad spectrum of scripts, languages, and painting styles depending on the region of origin and purpose of dissemination. The manufacturing material reflects the various influences in the oasis sites. Based on analyses of some pigments, examples are posed.
The objective of this study is to find out how far geochemical characteristics of the blue mineral pigment can be confirmed in respect to its provenance. In dependence of the quantity of samples analysed from a special geological region and the methods applied, a range of variation is taken into consideration. To provide clues, a multi-technique analytical approach with µXRF and ESEM is applied to samples from the most famous deposits.
Special elements determined as fingerprint are related to the textural features corresponding directly to the geological conditions of forming. The results and the statistical output allow a differentiation that enables an optimized local classification of the blue stone. To be aware of the limits of analysis is an absolute requirement for each geo-tracing implemented on blue coloured cultural objects of unknown provenance. For testing the possible sources of lapis lazuli, the blue pigment used as paint on murals and as ink on manuscripts from the Silk Road is analysed in an exemplary way.
The writing materials of the Silk Road book cultures in Turfan – Analysis of inks and pigments
(2014)
Manuscript fragments discovered in the oasis of Turfan and in other sites of present-day China in the beginning of the 20th century by A. Grünwedel and A. von Le Coq, represent one of the most fascinating cultural testimonies of people who both lived there and travelled along the trade routes between East and West. To determine the different materials used for writing and painting the Chinese, Sanskrit, Manichaean, Syrian, Sogdian, Tocharian and Uighur fragments of the Berlin collection, analysis of inks and pigments were conducted using non-destructive methods. The research was funded by the German Research Foundation DFG for a period of three years. The identification of specific techniques of preparation allows manuscript groups and sub-groups to be specified, aiding their cultural assignment. This is important for further cultural studies, for the development of conservation strategies and the identification of forgeries.
