Kewl documentary on The Science Channel-- "Hot Rocks: Geology of Civilization". Saw it this morning (4-5-07) but no doubt it'll repeat many times. The gist was basically "geology meets ancient art", in terms of how artists, from the first cave painters through ancient Egyptians , up to Van Gogh, used minerals to derive the colors in their paints. A bit of chemistry, a bit of geology, and a bit of art history--- when, where, & how did ancient painters move beyond reds & ochres, to greens, and later, to the first blues? How did the Egyptians use a chemical process to turn malachite blue, for their paintings? Etc. Good stuff. Well done, lots of beautiful footage of rock walls, paintings, etc.
