Abstract:

This paper refers to the study of the Voyatzis mansion, in the port of Aegina, Greece. The building complex consists of two discrete structures, which were built at different times (before 1830, 1880 and 1890) and have housed either the Voyatzis family home or its business and work premises. The present research is focused on the documentation of the building, which was never published, and combines the architectural form and elements within its historical context as well as the physicochemical analysis of the painted decoration. The key hypothesis investigated is whether Konstantinos Voyatzis transferred the aesthetic approach and application techniques from Symi to Aegina, when he emigrated from his birthplace. The documentation of the ceiling decoration as well as the physicochemical study of the second floor’s internal wall painting decoration in the main rooms was carried out using in situ modern hyperspectral imaging in specific wavelengths of the visible and near-infrared region, as well as in false color infrared mode. Complementary SWIR imaging, using an InGaAs sensor at the range 900–1700 nm was also applied. The assumption was supported by the findings of the imaging techniques, which showed, apart from the secco method, the use of traditional pigments for the wall paintings, such as cobalt blue, brown, red and yellow earth pigments, chrome oxide green and black, sometimes in admixture with white. The use of guidelines and stencil in the case of the hallway was also recorded.
