How representative the descriptions are and what they tell us about the era are still strongly debated. For example, a question that arises is whether the authors of the scrolls were members of a monastic sect or in fact mainstream. A conference marking 60 years since the discovery of the scrolls will begin on Sunday at the Israel Museum in Jerusalem, where the stone, and the debate over whether it speaks of a resurrected messiah, as one iconoclastic scholar believes, also will be discussed.

Oddly, the stone is not really a new discovery. It was found about a decade ago and bought from a Jordanian antiquities dealer by an Israeli-Swiss collector who kept it in his Zurich home. When an Israeli scholar examined it closely a few years ago and wrote a paper on it last year, interest began to rise. There is now a spate of scholarly articles on the stone, with several due to be published in the coming months.

“I couldn’t make much out of it when I got it,” said David Jeselsohn, the owner, who is himself an expert in antiquities. “I didn’t realize how significant it was until I showed it to Ada Yardeni, who specializes in Hebrew writing, a few years ago. She was overwhelmed. ‘You have got a Dead Sea Scroll on stone,’ she told me.”

Much of the text, a vision of the apocalypse transmitted by the angel Gabriel, draws on the Old Testament, especially the prophets Daniel, Zechariah and Haggai.

Ms. Yardeni, who analyzed the stone along with Binyamin Elitzur, is an expert on Hebrew script, especially of the era of King Herod, who died in 4 B.C. The two of them published a long analysis of the stone more than a year ago in Cathedra, a Hebrew-language quarterly devoted to the history and archaeology of Israel, and said that, based on the shape of the script and the language, the text dated from the late first century B.C.

A chemical examination by Yuval Goren, a professor of archaeology at Tel Aviv University who specializes in the verification of ancient artifacts, has been submitted to a peer-review journal. He declined to give details of his analysis until publication, but he said that he knew of no reason to doubt the stone’s authenticity.

It was in Cathedra that Israel Knohl, an iconoclastic professor of Bible studies at Hebrew University in Jerusalem, first heard of the stone, which Ms. Yardeni and Mr. Elitzur dubbed “Gabriel’s Revelation,” also the title of their article. Mr. Knohl posited in a book published in 2000 the idea of a suffering messiah before Jesus, using a variety of rabbinic and early apocalyptic literature as well as the Dead Sea Scrolls. But his theory did not shake the world of Christology as he had hoped, partly because he had no textual evidence from before Jesus.
