1. Regarding paint chemistry, I'm not at all certain how many artists' pigments of the Middle Ages and Renaissance contained lead. Also considering the differences in techniques required different compositions. For instance, there were watercolors, tempera (based on egg white), oils, etc. Applied to various bases (wood, various fabrics, leather, and fresh plaster). For architectural pigments, I read somewhere that milk-based paints were popular because they were cheap considering the large areas to be covered; these were used into the 19th cent. and there is at least one company still making bovine pigment for historical restoration purposes -- and it's no longer an economy priced product. 2. Licking of brushes -- makes some sense with watercolor or tempera, but sounds mighty unpleasant with oil paints! Eesh! 3. Madness, like insanity, are common vernacular and literary terms but have not been part of the legal or medical vocabulary for donkey years. Human behavior is affected by a lot of factors -- glandular and cerebral function and chemistry are complex issues. 4. Celebrated heroes of the past -- they become more heroic and less dastardly as they recede into the historic past, and after novelists and Hollywood have their say! |
