Judea's most consequential modern discovery came out of caves above the Dead Sea, and it changed what could be known about the religion of the region in the last centuries BCE.
Between 1947 and 1956 scrolls and fragments were recovered from eleven caves near Qumran: copies of every book of the Hebrew Bible except Esther, a thousand years older than the previously oldest manuscripts, together with commentaries, hymns, a rule for community life, and a document describing a war between the sons of light and the sons of darkness. They show a Judaism far more varied than the later rabbinic sources suggest, with a solar calendar in use alongside the lunar one, an intense interest in purity, and a group that considered the Jerusalem temple establishment illegitimate.
The site beside the caves has been interpreted in several ways. Jodi Magness's account of the archaeology supports the identification of the settlement as a sectarian community with the scrolls as its library, probably connected to the Essenes described by Josephus and Philo, while other scholars have argued for a fortified estate, a pottery works or a country villa with the scrolls hidden there from elsewhere.
The scrolls' publication was slow and contested for decades, which generated a substantial literature of suspicion about what was being withheld. The full corpus is now published and available, and the sensational readings have not survived it.
