"The Book of Lamech was so fragile that seven years went by before it could be unrolled. It was assumed to be the lost Apocryphal Book of Lamech, but it proved to be a document in Aramaic relating to the Book of Genesis. It is now called the Scroll of the Apocryphal Genesis. It describes the journeys of Abraham."
"When scholars got a look at a small fragment of the seventh and last of the Dead Sea Scrolls found in Jordan in 1947, they discovered the name of Lamech, the father of Noah. They concluded that the seventh scroll was an apocryphal Book of Lamech. There the matter stood, for the seventh scroll seemed too brittle to be unrolled.

In 1954 Israel bought the seventh scroll (and three others) from Jerusalem's Syrian Metropolitan Mar Athanasius Samuel, and experts at Hebrew University tackled the problem of unrolling it. Slowly softened by humid air, the leather scroll finally opened. Its center yielded four complete and legible pages and several fragments. Last week the secret of the seventh scroll was revealed. It proved to be a warning against jumping to conclusions about the Dead Sea Scrolls.
Far from being part of the Book of Lamech, the pages were an Aramaic version of Chapters 12 to 15 of Genesis, interwoven with stories and legends about the Patriarchs. As scholars examined the scroll further, it became clear that all of it deals with the Book of Genesis in the same order as the accepted text. The fragment mentioning Lamech that had misled the scholars was evidently part of Chapter 5 of Genesis."
