An immense ancient clock, which could be seen from afar, was set in the tower. Its complicated mechanism occupied an entire story of the structure, and it was under the care of a one-eyed man who could use a magnifying glass with expert skill. This was the reason why he had become a clockmaker and had tinkered for years with small timepieces before he was given charge of the large clock. Here he felt at home and happy. Often, at odd hours, without apparent need he would enter the room where the wheels, the gears and the levers moved deliberately, and where the immense pendulum cleft the air with wide and even sweep.
