Hornfels Quotes

“The next stage is a hornfels, a thoroughly recrystallized rock, so named after its supposed resemblance to animal horn. Hornfels has one rather unexpected quality—when suitably shaped, it can produce beautiful musical notes when struck. Indeed, it took central place in an extraordinary narrative of the English Lake District. An eccentric 18th-century inventor, Peter Crosthwaite—a fighter against Malay pirates in his youth and, later in life, the founder of a museum in the town of Keswick—built a kind of xylophone using hornfels from the local Skiddaw mountain. Half a century later, the Keswick stone-maker and musician Joseph Richardson determined to top Crosthwaite’s achievement, and almost ruined his family financially by building an even bigger instrument, which would produce a larger range of musical notes. Once built, though, it was indeed a sensation. Richardson toured England for three years with his sons, playing Handel, Mozart, and dance tunes on his rock creation—though at times restraining the power of the instrument so it would not shatter concert hall windows. Queen Victoria liked the performances so much that she requested extra concerts (although reports from the time do suggest that she was not amused at its imitation of Alpine bells). The harmonious hornfels ‘lithophones’ may still be seen in the Keswick museum—and are to this day occasionally taken on musical tour.”
