The XXIII Symposium will provide a scientific forum for the presentation of new technical studies in art history, concentrating on art from the Middle Ages and Early Modern period (1400-1600). The conference will focus on the technical examination of art in a variety of media and supports: panel paintings, painting on parchment and canvas, drawings, cartoons, sketches, model- and sketchbooks, prints and manuscript illuminations. The main theme will be cross-media perspectives in the context of artistic materials, working methods, and the dissemination of concepts. Similarities in design might indicate cultural, social, geographical, or chronological connections in paintings, drawings, prints etc. as well as links across other artistic media. Recent developments in viewing platforms, artificial intelligence and machine learning can offer alternative possibilities in this research field, stimulate contacts and the exchange of experience, and form a bridge between art and science.
