It was told from olden days, and written in the books of Snorri Sturlason, that the Asa or Ansa folk came from the land of Tanais to the North. They soon became overlords; from the high hall they raised at Upsala their power spread, until even the German tribes drew chieftains and learning from them. For they were good masters, who brought their new people not only wealth but knowledge. They gave to the North crafts of both peace and war, such as the building of longships and the breeding of fine horses, the writing of runes and the mustering of armies, foreign trade and foreign travel, much leechcraft and many wise laws. By all this the folk were strengthened and helped, so that they lifted themselves from rude forest dwellers to mighty nations who finally overthrew the Roman power and peopled Europe afresh, in the time of the Wanderings. Above all did they shape the country called England, and there they kept much of the old freedom-shielding law that the Asa men first brought.

Every king in the North reckoned descent from the Asa lords, who themselves came to be worshiped as gods after they died. The first Asa king was called Odin, and he was the chief of the gods.
