MORTAR ANALYSIS OF WALL PAINTING AT AMFISSA CATHEDRAL FOR CONSERVATION – RESTORATION PURPOSES

Abstract

Contemporary artist Spyros Papaloukas in 1932 undertook a major artistic venture, the painting of the inte- rior murals of the Amfissa Cathedral (Church of the Annunciation) a cross-domed church built in 1868 on the ruins of an early Christian basilica. In this 1000 sq monumental work, Papaloukas, even though he fol- lows the strictly established rules of Byzantine ecclesiastical art, he dares to attempt a new approach to the aesthetic merits of Byzantine iconography by introducing elements of the post- Impressionists, the Fauves and the Nabis. Following our earlier work of spectroscopy of mural paintings in this Cathedral, here we pre- sent the analysis of ten mortar wall samples regarding granulometry and mineralogy, by XRD, SEM, as well as, a study of resistance-breaking and the level of mechanical strength was determined by comparing the diagrams of power – displacement, where the compressive strength of mortars ranged between 0.5-0.8MPa.
