Analysis of the Wall Painting of the Dunhuang Fresco as a Basis for Its Preservation and Restoration

The article analyses the wall paintings of Dunhuang sanctuaries based on mathematical methods of defining features and system-structural analysis. This makes it possible to analyse the frescoes according to a certain common criterion and to identify common and different ones. The method of system-structural analysis made it possible to present the sanctuary as a certain integrity with components covered with decor and decorated with sculpture. The main thematic genres of frescoes by period were analysed and it was proved that, in general, the process of the genesis of plans, structural schemes and wall paintings from the early to middle and late periods had the same characteristics, that is, the features of archaism and simplicity characterized both the number and variety of plans and structural schemes, and the subjects of frescoes. The features of each genre at different periods are determined.
