By Professor Emeritus Philip Alexander (Manchester) in the Guardian. Excerpt:
Geza Vermes, who has died aged 88, was one of the world's leading authorities on the origins of Christianity. In the early 1950s he completed the first-ever doctorate on the Dead Sea Scrolls – a risky topic to choose. In 1947, an Arab shepherd had chanced upon the first scrolls – texts written in ancient Hebrew and its sister language Aramaic – in a cave in the cliffs along the north-west shore of the Dead Sea. These were published rapidly, but reports kept circulating that more caves containing more manuscripts were being found. No scholarly consensus had yet emerged as to when the scrolls were written, or by whom. Wildly fluctuating dates were assigned to them, some even claiming that they had been copied in the middle ages.And another, brief one in the Washington Post: Geza Vermes, religious scholar. More like "scholar of religion," but maybe the difference is too subtle for the media.
From careful analysis of the published material, Vermes argued that the Jewish sect behind the scrolls originated at the time of the Maccabean crisis in the middle of the second century BCE. It was a brilliant hypothesis which gained many adherents and became academic orthodoxy. Vermes himself never saw grounds for modifying it throughout his career.
