Much of the previous sixty years (1949-2009) have been devoted to the cleaning of the Dead Sea scrolls, their piecing together and their translation. The present volume is a scientific study of the various archaeological relics that have been found in the three units at Qumran: The settlement, the caves with the scrolls and the cemetery. With the aid of neutron activation of Qumran's pottery we established its human relations with neighboring sites, by radio carbon dating we placed the relics in their time frame, by DNA we study the provenance of the animal hides that served the scribes as parchment. The ink is studied for examining the degradation processes that started when the scrolls were written, 2000-2300 years ago.
