The Book of Jasher

And the sun stood still, and the moon stayed, until the people had avenged themselves upon their enemies. Is not this written in the book of Jasher? So the sun stood still in the midst of heaven, and hasted not to go down about a whole day.
"The Book of Jasher includes details about antediluvian patriarchs which are confirmed by modern revelation. The question arises of how the author of Jasher could have known specific facts from before the Great Flood, such as Cainan becoming very wise when he was forty years old. These correlations attest that it was composed from exceedingly ancient reliable sources."

Notes

There are multiple versions of the Book of Jasher.

The version published by J.H. Parry & Company, 1887 does not seem like a very good candidate for the original Book of Jasher. The contents feel largely romantic, suggesting a middle-ages origin or corruption, and the stories appear to contradict revealed history. The story of Enoch, in particular, feels completely nonsensical. Enoch, in particular, is described as something of an ascetic, who, by virtue of his days meditating in a cave, receives the wisdom to bring peace to the world as king, before wandering off into the wilderness and disappearing mysteriously with some of his followers. This is in contrast to Joseph Smith's account which makes him king of the City of Enoch, which he brings into a Zion state while the world outside is wicked, before, eventually, the city is translated from the Earth. Again, we have the story of Lamech. In this Book of Jasher, Lamech kills Cain accidentally, and then his own son, Tubal-cain, because he goes mad with grief. Per the Book of Moses, however, it is only Irad who is killed, because Irad was exposing the secret combinations. It is not impossible that this is a reworking from some old legitimate sources. The 2002 article from Meridian Magazine notes some interesting details that this Book of Jasher shares in common with Joseph Smith's revelations, but if its source was originally good, it clearly contains many fanciful interpolations as well.

It would probably be interesting to do a more thorough point-by point comparison of the Book of Jasher and our modern understanding of the same history.
