Ancient writings often describe how Celts in the Iron Age would remove the heads of their enemies to keep as trophies. Impressive, sure, and a great conversation piece at parties, but how would they keep the heads from rotting? Apparently, Celts (ancient and medieval Celtic speakers) would embalm the severed heads to solve this problem, and researchers may have recently figured out how they did it. The team believes that the heads may have possibly been dipped in cedar oil or a local pinacea oil after the brain was removed for embalming. This new evidence, however, helps verify some of what has been written about the embalmed heads.
