Jacob's ladder
Genesis (28:11-19): 'Taking one of the stones of the place, he put it under his head and lay down in that place to sleep. And he dreamed that there was a ladder set up on the earth, and the top of it reached to heaven; and behold, the angels of God were ascending and descending on it!' (ook Jacob ontsnapte duidelijk niet aan de effecten van zuurstoftekort...)
