1,200-year-old phone

There’s a 1,200-year-old Phone in the Smithsonian Collections.

The gourd-and-twine device, created 1,200 to 1,400 years ago, remains tantalizingly functional—and too fragile to test out. “This is unique,” NMAI curator Ramiro Matos, an anthropologist and archaeologist who specializes in the study of the central Andes, tells me. “Only one was ever discovered. It comes from the consciousness of an indigenous society with no written language.”

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. “The Chimu were a skillful, inventive people,” Matos tells me as we don sterile gloves and peer into the hollowed interiors of the gourds. The Chimu, Matos explains, were the first true engineering society in the New World, known as much for their artisanry and metalwork as for the hydraulic canal-irrigation system they introduced, transforming desert into agricultural lands.
