The Transfer of Murals with an Uneven Surface upon the Example of the Conservation of Paintings from the Ceiling of a Mithraeum in Huarte

Summary/Abstract: A mithraeum, decorated with paintings and originating from the fourth century A. D., was discovered in 1997 underneath the floor of the Syrian church from the sixth century A. D. The painted rock ceiling of the temple caved in during archaeological excavations, and the only way of saving the murals was to transfer them onto a new basis. The conducted conservation made it possible to exhibit the disintegrated painting while retaining the specificity of its original surface. A new type of facing was used for rendering indelible the original plaster – a negative was made of the traditional carriers in the form of cotton gauze and linen cotton, reinforced with ribbing made of Kapa-plast plates. The conservators also used a modified type of substitute foundation construction – an inner lining laminate with a Kappa-plast plate bracing truss covered with linen cloth. The truss chambers were filled with polyurethane foam, which was then laminated with an outer facing. The whole construction was additionally reinforced by installing a framework made of aluminium profiles with a system of thin wires stretched inside the foaming polyurethane. The applied material made possible a maximum reduction of the burden of the transfer. The purpose of the presented study was to devise a method of transferring the remaining part of the paintings in the mithraeum. In time, the progressing degradation of the rock foundation will make it necessary to shift also those paintings which today remain in situ.
