Sweden: 1,500-year-old onion discovered
Archaeologist Helena Victor however explained that onions were not grown in Scandinavia at the time. She thinks the onion 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.
According to archaeology.org, at one time 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.
