Collects studies on the dating and scientific characterization of prehistoric and ancient wall paintings, combining archaeological interpretation with physical and chemical analysis. Contributions address colour perception and measurement, pigment identification using Raman microspectrometry, and the composition and use of iron-oxide pigments, green earths, Egyptian blue and green frit. Studies of Greek painting and ancient polychromy relate analytical findings to painting techniques and historical context. The volume provides an interdisciplinary reference for investigating the materials, chronology and conservation of painted surfaces.
