A Fragment about Enoch's Tablets
(excerpted from the Slavonic Version of the Palaea Historica)
Concerning Enoch. Enoch was born and became a good and devout man, who fulfilled God’s will and was not influenced by the counsels of the giants. For there were giants (on earth) at that time. And Enoch was translated (to heaven) by God’s command, and no one saw [how] his removal [happened].
Concerning Noah. In the days when the giants were around and did not want to glorify God, a man was born whose name was Noah, who was devout and feared God, and like Enoch he was not influenced by the giants’ counsels....
... When the giants heard that the righteous Noah was building an ark for the Flood, they laughed at him. But Enoch, who was still around, was also telling the giants that the earth would either be destroyed by fire or by water. And the righteous Enoch was doing nothing else but sitting and writing on marble (tablets) and on bricks the mighty works of God which had happened from the beginning. For he used to say: “If the earth is destroyed by fire, the bricks will be preserved to be a reminder [for those who come after] of the mighty works of God which have happened from the beginning; and if the earth is destroyed by water, the marble tablets will be preserved.” And Enoch used to warn the giants about many things, but they remained stubborn and impenitent, nor did they want to glorify the Creator, but instead each [of them] walked in his own will of the flesh...
