Lecture by Dr. David Hradil from the Institute of Inorganic Chemistry, Academy of Sciences of the Czech Republic, Rez at the Institute for Natural Sciences and Technology in the Arts.
The main objective of this lecture is to show the importance of using the knowledge of geosciences in the interpretation of origin of historical paintings. Mineral pigments will be discussed as indicators usable for the dating and tracing the provenance of anonymous paintings as well as for the attribution of the authorship. In this point, an advanced materials microanalysis (based mainly on powder X-ray micro-diffraction) will be combined with further descriptions of technological and artistic fingerprints. A special attention will be given to pigments related to ore mining in Middle Ages (iron reds, azurite, fluorite etc.), further to clay pigments, and finally to pigments important from the point of view of technology transfers (e.g. lead-based yellows). In the case studies, successful assignments to particular periods, regions or workshops based on materials data will be demonstrated.
David Hradil is a mineralogist specialised to the
microanalysis of pigments, provenance studies and the processes of
chemical interactions in painting layers. He published numerous papers
focused on mineralogical analysis of historical paintings and
methodological developments in the field. Since 2004 he has headed
laboratory ALMA - joint workplace of the Academy of Fine Arts in Prague
and the Institute of Inorganic Chemistry of the Czech Academy of
Science, which intentionally promotes and applies an interdisciplinary
approach to the cultural heritage research combining science, art and
humanities within one closely collaborating team.
