In 793 Vikings mugged, maimed, and murdered the monks on Northumbria's Holy Island, shocking western Christendom. Joining us to discuss the first Viking attack on a monastery in the British Isles is our debut guest expert, Dr Ben Allport, co-creator of the Viking age, a valuable online resource for students and teachers of Viking history, society, and culture. Warning: wearing frivolous clothing can cause a Viking attack.
