The human story began in a cave; the cave which popular science associates with the caveman and in which practical discovery has really found archaic drawings of animals. The second half of human history, which was like a new creation of the world, also begins in a cave. There is even a shadow of such a fancy in the fact that animals were again present; for it was a cave used as a stable by the mountaineers of the uplands about Bethlehem; who still drive their cattle into such holes and caverns at night. It was here that a homeless couple had crept underground with the cattle when the doors of the crowded caravanserai had been shut in their faces; and it was here beneath the very feet of the passers-by, in a cellar under the very floor of the world, that Jesus Christ was born.

In the riddle of Bethlehem it was heaven that was under the earth.
