| Abstract: | Designed as grisaille, the paintings of the Hercules-Hall in Bertholdsburg Castle have probably been ordered by Count Georg Ernst (1511-1583), the last count of the county Henneberg. Following a period of secondary use of the hall, the paintings were rediscovered under layers of lime-wash and paint in the early 20th century and had already been treated extensively in the 1950s. Within this thesis, the development of a concept for the conservation and restoration of the mural paintings shall be presented, starting with the determination of the need for restoration, based on an analysis of the original material and its condition, through to an exemplary, practical implementation on a reference area. Extensive studies of the so-far unexplored paintings form the basis of this concept and represent therefore the main part of this work. With the help of extensive investigations in the laboratory and radiate diagnostic investigations, the original material and its condition had been analysed. In addition to the determination of the extent and the degree of damage, a genesis of the damage could be established. An analysis of the causes for the damage pointed mainly at climatic and structural reasons. Moreover, an impairing effect predominantly with regard to the aesthetics, but also with regard to the conservation aspect, could be assigned to the measures which were carried out in the 1950s. In particular, the measures taken to treat the cavities can be regarded as aggravating, sometimes even initiating the process of deterioration. Beyond the art-technological aspects, art-historical research established engraved templates as the basis for the painted scenes of Hercules. Nearly analogue representations of figures in a series of tapestries made for Duke Albrecht V. (1550-1579) provide further opportunities for a more detailed statement regarding the genesis of the paintings at the end of 16th century. |
