The Vikings were a fascinating people and there is so much more to learn about them, but this is a good summary or overview for those just starting out on reading about the Norse culture.
The poem/sagas called The Edda's were written in Iceland during the Middle Ages and show a stern people with serious beliefs. However, the Norse people took intense pleasure from such things as friendship, food, love, wittiness and fighting bravely in battle.
I hope this serves as a good summary or overview. Stay tuned for more mythology creations in books to come.
