High in Erin sang the sword

From Njal's Saga, one of the greatest sagas of Iceland, usually dealing with epic feuds across the vast tracts of Nordic North Atlantic expansion including Ireland, Scotland, Shetland and lands west.

I have been where warriors wrestled,
High in Erin sang the sword,
Boss to boss met many bucklers.
Steel rung sharp on rattling helm;
I can tell of all their struggle;
Sigurd fell in flight of spears;
Brian fell, but kept his kingdom
Ere he lost one drop of blood.
