ISLE OF COLL, SCOTLAND—An excavation on a Royal Society for the Protection of Birds (RSPB) nature reserve has uncovered 3,000-year-old swords and spearheads made of bronze. The twelve pieces are thought to have come from at least seven weapons. “The items were recovered from what had once been a freshwater loch. It seems that they had been purposely broken and cast into the waters as part of a ceremony, most likely as offerings or gifts to the gods or goddesses of the time,” Jill Harden, RSPB Scotland Reserves archaeologist, said in a press release. Further study could reveal if there were environmental stresses that prompted the offering. The artifacts have been moved to Kilmartin Museum in Argyll for conservation.
