“ The square was soon filled with an enthusiastic populace, every moment expecting the superstructure to go down. Bernini, on hear- ing this state of things, proceeded to the square in his carriage; arriving in front of his work, disregarding the hisses and groans of the people, he ordered ladders, connected them together, and ascending to the top of the obelisk, drew from his pocket a ball of twine, unwound until he had four strings, each of sufficient length to reach across the square, and fastened one end of each to the top of the column. ”
