On South Africa’s southern coast, above the mouth of the Matjes River, a natural rock shelter nestles under a cliff face. The cave is only about 3 meters deep, and humans have used it for more than 10,000 years.
The place has a unique soundscape: The ocean’s shushing voice winds up a narrow gap in the rocks, and the shelter’s walls throb with the exhalation of water 45 meters below. When an easterly wind blows, it transforms the cave into a pair of rasping lungs.
It is possible that some 8,000 years ago, in this acoustically resonant haven, people not only hid from passing coastal thunderstorms, they may have used this place to commune with their dead—using music. That’s a possibility hinted at in the work of archaeologist Joshua Kumbani, of the University of the Witwatersrand in Johannesburg, and his colleagues.
Kumbani, with his adviser, archaeologist Sarah Wurz, believes they have identified an instrument that humans once used to make sound buried within a layer rich with human remains and bone, shell, and eggshell ornaments dating between 9,600 and 5,400 years ago. This discovery is significant on many levels. “There could be a possibility that people used it for musical purposes or these artifacts were used during funerals when they buried their dead,” Kumbani hypothesizes.
The work offers the first scientific evidence of sound-producing artifacts in South Africa from the Stone Age, a period ending some 2,000 years ago with the introduction of metalworking. That “first” is somewhat surprising. Southern Africa has afforded archaeology a wealth of findings that speak to early human creativity. There is evidence, for example, that humans living 100,000 years ago in the region created little “paint factories” of ochre, bone, and grindstones that may have supplied artistic endeavors. Engraved objects found in the same site, dating back more than 70,000 years, hint at their creator’s symbolic thinking.
