cannot be a coincidence that western European cave painting declined at just the same time. Fewer and fewer artists crawled under the ground with their animal-fat lamps and sticks of ocher. Sometime around 13,500 years ago the very last artist walked away. He or she probably did not realize it, but on that day the ancient tradition died. Darkness fell in the caves, and for millennia only bats and dripping water disturbed their tomblike silence.
