The Book of the Cave of Treasures 15

1And when Adam was dead his son Seth embalmed him, according as Adam had commanded him, with myrrh, and cassia, and stakte; now Adam’s dead body was the first [body buried] in the earth. And grief for him was exceedingly sore, and Seth [and his sons] mourned for his death one hundred and forty days; and they took Adam’s body up to the top of the mountain, and buried it in the Cave of Treasures. And after the families and peoples of the children of Seth had buried Adam, they separated themselves from the children of Cain, the murderer. And Seth took Anésh, his firstborn, and Kainan, and Mahlalail, and their wives and children, and led them up into the glorious mountain where Adam was buried; and Cain and all his descendants remained below on the plain where Cain slew Abel.
