STOCKHOLM, SWEDEN—According to a report in The Local, a burned lump recovered near a fireplace at Sandby Borg on the island of Öland is a 1,500-year-old onion. However, archaeologist Helena Victor explained that onions were not grown in Scandinavia at the time. She thinks the vegetable may have been imported from the Roman Empire as an exotic vegetable. “An onion doesn’t sound very interesting,” Victor said, but she notes that the next-oldest onion to have been found in Scandinavia dated to A.D. 650. The inhabitants of Sandby Borg were killed and the settlement burned by unknown attackers. Victor suggests imported items such as the onion, as well as Roman gold rings and coins found in the ancient ring fort, may have been a motive for the massacre.
