The story of the discovery of the first Dead Sea Scrolls has become a part of Western lore. Who has not heard about the Bedouin shepherd who threw a rock into a cave, heard a crash, went in to explore, and found the scrolls? The story in that form may be accurate, but it turns out to be something of a simplification. As a matter of fact, much remains unknown about the exact circumstances under which those scrolls were discovered. The story of the discovery at first deals with just one cave; the other ten were located at later times.
