Erland Nordenskiöld listed the Itonama among the peoples whose bullroarers he carried out of Bolivia, and then wrote nothing whatever about what the sound was for — a silence Otto Zerries, sorting South America's roarers four decades later, could not fill either. What survives instead is the rig itself: a narrow thirty-centimetre blade off the Rio Machupo, austere to the point of plainness, and a cord that runs on far beyond the wood, still attached. Most museum bullroarers lost that cord long ago.
