Ancient fortress in the Judean wilderness, famed for the last stand of the Zealots in the war against the Romans in 70 C.E. In recent years it has been the site of much archaeological activity. In 1965, Prof. Yigael Yadin of the Hebrew University reported that his expedition had discovered a large piece of scroll belonging to the long-lost Hebrew original of the Book of Jubilees, one of the most important of Apocryphal writings.
