The Monastery on a Cliff

There is a story about a monastery perched high on a cliff several hundred feet in the air. The only way to reach the monastery was to be suspended in a basket which was pulled to the top by several monks who pulled and tugged with all their strength. Obviously the ride up the steep cliff in that basket was terrifying. One tourist got exceedingly nervous about half-way up as he noticed that the rope by which he was suspended was old and frayed. With trembling voice, he asked the monk who was riding with him in the basket how often they changed the rope.
The monk thought for a moment and answered brusquely, "Whenever it breaks."

Thomas Tompion

Died 20 Nov 1713 at age 74 (baptized 25 Jul 1639).Most famous English clockmaker of his time, especially known for watchmaking improvements. He worked closely with experimental physicist Robert Hooke, and in 1675, following Hooke's design, Tompion made one of the first English watches regulated by a balance spring. In 1695, with Edward Barlow and William Houghton, he patented the cylinder escapement (a controlling device) that allowed use of a horizontal wheel, enabling Tompion to make the first of the flat and more compact watches.[Image: Bracket clock with oak case ebony veneer, and gilt bronze mounts by Tompion, c. 1690.]
