We’ll never know the trial and error that went into its creation. The marvel of acoustic engineering—cunningly constructed of two resin-coated gourd receivers, each three-and-one-half inches long; stretched-hide membranes stitched around the bases of the receivers; and cotton-twine cord extending 75 feet when pulled taut—arose out of the Chimu empire at its height. The dazzlingly innovative culture was centered in the Río Moche Valley in northern Peru, wedged between the Pacific Ocean and the western Andes.
I can just see it now, ancient Peruvians up a mountain, on the phone to those below working away... Man on phone saying "Oi, that bits not vitrified enough"
