“Wake early if you want another man’s life or land. No land for the lazy wolf. No battle’s won in bed.” ~ A viking saying (Edda of Saemund the Wise, a collection of the sayings of Odin). This viking saying makes sense—a nation that does not awake early to the political realities will lose its land and culture.
The vikings were not doctrinaires. Their religious and cultural tradition was oral. But they were good political thinkers. There is a lot that can be learned from their history. Between the eighth and eleventh centuries, they played a major role in awakening the West from the slumber in which it had fallen after the end of the Western Roman Empire.
