Sitting on the shore of one of the fjords that are close to Oslo, watching the sea become one with the horizon, it seemed crystal clear why the Vikings set out to explore the seas.
How could you resist not knowing what lies beyond the thin blue line on the horizon?
It is easy when you are in-land to find something to rest your eyes on and aim to reach. There is always a steeple, a hill, a mountain that pierces the horizon and that calls you towards it to explore it.
When you see nothing but sea around you, how could you resist the pull of finding out what lies beyond? What a tantalising pull. Of course the Vikings had to set out at sea. They had to find the next best thing.
