Ancient Civilizations
The exhibition Scrolls From the Dead Sea: The Ancient Library of Qumran and Modern Scholarship brings before the American people a selection from the scrolls which have been the subject of intense public interest. Over the years questions have been raised about the scrolls' authenticity, about the people who hid them away during the period in which they lived, about the secrets the scrolls might reveal, and about the intentions of the scrolls' custodians in restricting access.
