I got interested in the Vikings, and then you realize that there isn't much to be read about them because they did not write their history. It was written by hostile witnesses, by Christian monks and so on. From what I could see and understand, I was really excited about it. I loved their culture and loved their gods.

The Vikings certainly didn't write anything about themselves; it was not a literate, but rather a pagan, culture. So what we get was written later by Christian monks. But there were occasional reportings and recordings of people who had traded usually with the Vikings.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
