CANBERRA, AUSTRALIA—The Iron Age artifact discovered in Ireland was originally thought to have been a spear-butt. However, Billy Ó Foghlú, a PhD student at the Australian National University, thought that it might have been part of a musical instrument, so he created a replica based on the object’s exact measurements using a 3D printer. When Ó Foghlú used the object as a horn mouthpiece, he found that it produced a rich, velvety tone. “These horns were not just hunting horns or noisemakers,” said Ó Foghlú in a press release. “They were very carefully constructed and repaired, they were played for hours. Music clearly had a very significant role in the culture.” Horns dating to the Bronze and Iron Ages have been discovered throughout Europe, particularly in Scandinavia, though according to Ó Foghlú no other mouthpieces are known to have been found in Ireland.
