At this time the aforesaid brothers, their allies forsaking them, built a very high rampart within an island surrounded by a swift stream, also extending their earthworks along the level.

Trusting to this refuge, they harried the neighborhood with continual raids.

For they built a bridge on which they used to get to the mainland when they left the island.

This bridge was fastened to the gate of the stronghold; and they worked it by the guidance of ropes, in such a way that it turned as if on some revolving hinge, and at one time let them pass across the river; while at another, drawn back from above by unseen cords, it helped to defend the entrance.
These warriors were of valiant temper, young and stalwart, of splendid bodily presence, renowned for victories over giants, full of trophies of conquered nations, and wealthy with spoil.

I record the names of some of them--for the rest have perished in antiquity--Gerbiorn, Gunbiorn, Arinbiorn, Stenbiorn, Esbiorn, Thorbiorn, and Biorn.
