I must be working on the novel, because I’m not progressing very fast in my reading of Caimh McDonnell’s latest book (which is great, by the way; it’s not for lack of interest). In case you’re losing sleep over my car repair problems, I learned today that the ETA for the replacement part is now June 30. This was, as you might expect, no surprise to me at all at this point.

What shall I write about? How about something I learned from John Marsden’s Harald Hardrada book (favorably reviewed a few inches down)?

It has to do with King Olaf Haraldsson, Saint Olaf (or Olav) of Norway. He appeared in my latest book, The Elder King, and also has a major role in the one I’m working on, King of Rogaland.

I do not like this man. He emerges as a recognizable character in the sagas, and although those sagas are generally intended to promote his sainthood, the writers often had the insight to “paint him warts and all.” And this was a guy with a lot of warts.

Marsden’s book includes an interesting discussion of the date of the Battle of Stiklestad, where Olaf was killed. (Incidentally, I recently learned that one of my great-grandfathers was born on the island of Ytterøy, which is located in a fjord and almost in walking distance of the battlefield [once you get out of the water]).

There’s an anomaly in the standard accounts of the battle. The very first skaldic poems celebrating it (written by Sigvat the Skald, who also appears in The Elder King), tell how a solar eclipse occurred in the very midst of the battle. The problem is, the traditional date for the battle is July 29, but the eclipse occurred August 31. I’ve always inclined to the view that people remembered the battle and the eclipse as extraordinary events, and eventually conflated them. But Marsden points out that Sigvat (who wasn’t in the battle; he was on a pilgrimage to Rome at the time) would have been well-informed about the battle at a very early date. Also, the time of day given for the eclipse in the sagas is spot on.

Marsden passes on a possible explanation, suggested by “the editor of a long-respected English translation of Olaf the Saint’s saga.” This theory involves an error in interpreting a theoretical lost document (which I always consider a tenuous stratagem for scholars), but it works out quite neatly. If the original text of this X Document said that the battle occurred “1029 years and two-hundred and nine days since Christ’s birth,” and you reckon hundreds in the customary way, figuring January 1 as the first day of the year, you get July 29.

However – the Vikings counted in what are called “long hundreds.” When they said 100, they actually meant 120. All figures in the sagas need to be adjusted for that.

If you convert “1029 years and two-hundred and nine days” to long hundreds, and start your count at December 25 (a common date for figuring New Year’s Day at the time), you get the precise date of August 31.

That’s pretty neat, it seems to me. My plan, if I live so long, is to write a book about Olaf and Stiklestad a couple books from now, as a sort of sequel to Erling’s Saga. I think I’ll use this date for it, because that eclipse is a really cool bit of atmospheric staging.
