Severed head rituals were more widespread in Iron Age Iberia than we thought
Researchers now think at least two more groups joined the macabre custom. Breakthroughs, discoveries, and DIY tips sent six days a week. Archaeologists have spent years puzzling over evidence of severed head rituals among Iron Age communities in the northeast Iberian Peninsula. Multiple groups of the Indigetes and Laietani peoples from present-day Spain and Portugal practiced these violent public displays at least as far back as the first millennium BCE. And sometimes, they did so with elaborate preparation techniques such as driving iron nails through the skulls .
