It’s Friday, and I don’t have a book to review. What shall I do, what shall I do?

I note that yesterday was the anniversary of the Viking raid on Lindisfarne, off the coast of Northumbria, in 793. It would have been more appropriate to mention it yesterday, I suppose. The day before would have been even better, so you’d have time to plan your Lindisfarne celebrations. On the other hand, the Gregorian calendar reform of 1582 threw all our calculations off by 10 days anyway, so when we cite ancient dates we’re always approximating.

There’s some controversy among Viking scholars about the Lindisfarne raid. We have a strong movement going to downgrade the importance of the 793 date as the “official” beginning of the Viking Age. The Portland raid in 789 is often advanced as the true beginning — though there are disagreements whether that one should be considered a proper raid at all. Could have been just a harbor-side brawl with an officious customs officer. Some historians have begun pointing to the discovery of a ship burial containing dozens of men’s bodies on an island in Estonia and dated sometime between 700 and 750.

Personally, I’m inclined to continue accepting Lindisfarne and 793. When we consider the Viking Age as a historical period, we’re talking primarily about its impact on Western Europe. 793 was a 9/11 moment in that region, the moment when a previously disregarded threat suddenly became real and serious. The Portland raid didn’t have that effect, but Lindisfarne hit like a bomb. It was the equivalent of a raid on Oxford or Harvard today. It sent a message.

Above, a very nice video, a few years old, describing an exhibition of the famous Lindisfarne Gospels (a treasure the Vikings never got their hands on) in England.
