In 1900 a treacherous storm forced an expedition of Greeksponge divers off course from their fishing grounds in the Mediterranean. They took shelter near the coast of a remote island, Antikythera. While waiting for the storm to pass, they decided to dive for sponges. One of the divers noticed a disembodied arm half submerged in mud; on closer inspection, he found that it was made of bronze.

Its arcane staccato and euphonious intonation has become deeply ingrained in our language through the word’s use as a magical catchphrase. The hex was, in my childhood experience, rather useless when it came to opening locked cabinets and provoking instantaneous transformations; nothing was conjured and very little materialized except for my own disappointment. But millennia past, this word was held in reverence, […]
