Many, many years were passed in building the tower. It reached so great a height that it took a year to mount to the top. A brick was, therefore, more precious in the sight of the builders than a human being. If a man fell down, and met his death, none took notice of it, but if a brick dropped, they wept, because it would take a year to replace it. So intent were they upon accomplishing their purpose that they would not permit a woman to interrupt herself in her work of brick-making when the hour of travail came upon her. Moulding bricks she gave birth to her child, and, tying it round her body in a sheet, she went on moulding bricks.
