What about vikings? It's funny how a TV serie can push you to reflect about history. I already finish "The last kingdom" serie and I was really satisfied. It's pure entertainment. I know that we know almost nothing about the characters. But I also asked my self if some elements are related to real history: Is it the set (constructions) well documented and based on evidence? Are the blacksmith, carpenters, sailors techniques well described belong that age? I did not find yet information on Internet. The most intriguing think are the book that wrote King Albert on IX siecle. How many of those books survive today? Yesterday I start with the first episode of "Vikings"... And I already start to ask and research on navigation (and orientation) technique of that age. Maybe I'm too curious.
