Noah took the book, and when he studied it, the holy spirit came upon him, and he knew all things needful for the building of the ark and the gathering together of the animals. The book, which was made of sapphires, he took with him into the ark, having first enclosed it in a golden casket. All the time he spent in the ark it served him as a time-piece, to distinguish night from day. Before his death, he entrusted it to Shem, and he in turn to Abraham. From Abraham it descended through Jacob, Levi, Moses, and Joshua to Solomon, who learnt all his wisdom from it, and his skill in the healing art, and also his mastery over the demons.
