The interpretations of the Dead Sea Scrolls propagated by the overwhelming majority of Scrolls scholars start with the assumption that the Scrolls are not later than the second half of the first Christian century—more precisely, not later than June, A.D. 68—the only exceptions being those of one or two scholars who prefer a slightly later date. The exact terminus ad quem is not, however, based on any evidence contained in the Scrolls themselves, but was propounded by Père de Vaux as a conclusion derived from his excavations of the Qumran building and was taken over from him by the Scrolls scholars.
