called the Northmen, were becoming known and dreaded throughout the
world. Iceland and Greenland had been colonized by their dauntless
enterprise. Greece and Africa had not proved distant enough to escape
their ravages. The descendants of the Viking Rollo ruled in France as
Dukes of Normandy; and Saxon England, misguided by Ethelred the Unready
and harassed by Danish pirates, was slipping swiftly and surely under
Northern rule. It was the time when the priests of France added to their
litany this petition: "From the fury of the Northmen, deliver us, good
Lord."

The old, old Norwegian city of Trondhjem, which lies on Trondhjem Fiord,
girt by the river Nid, was then King Olaf Trygvasson's new city of
Nidaros, and though hardly more than a trading station, a hamlet without
streets, it was humming with prosperity and jubilant life. The shore was
fringed with ships whose gilded dragon-heads and purple-and-yellow hulls
and azure-and-scarlet sails were reflected in the waves until it seemed
as if rainbows had been melted in them. Hillside and river-bank bloomed
with the gay tents of chieftains who had come from all over the North to
visit the powerful Norwegian king. Traders had scattered booths of
tempting wares over the plain, so that it looked like fair-time. The
broad roads between the estates that clustered around the royal
residence were thronged with clanking horsemen, with richly dressed
traders followed by covered carts of precious merchandise, with
beautiful fair-haired women riding on gilded chair-like saddles, with
monks and slaves, with white-bearded lawmen and pompous landowners.

Along one of those roads that crossed the city from the west, a Danish
warrior came riding, one keen May morning, with a young English captive
tied to his saddle-bow.
