Long Ships of the Vikings
In September 1997 Danish archaeologists discovered a Viking longship in the mud of
Roskilde harbor, 40 kilometers (25 miles) west of Copenhagen. The discovery was the kind
of serendipitous event that earned Viking Leif Eriksson the appellation "Leif the
Lucky." Lying unsuspected next to the world-renowned Viking Ship Museum at Roskilde,
the longship came to light during dredging operations to expand the harbor for the
museum's fleet of historic ship replicas According to Ole Crumlin-Pedersen, former head of
the museum, the longship must have been sunk by a storm centuries ago, then hidden by
silt. Tree-ring dating of its oak planks showed that the ship had been built about A.D.
1025 during the reign of King Canute the Great who united Denmark, Norway, southern Sweden
and England in a Viking empire.
With its immense length of 35 meters, the Roskilde longship surpasses all previous
longship finds. By doing so, the ship also refuted skeptical modern scholars who judged
these leviathans, described in Norse sagas, to be as mythical as the dragon whose name
they bore. (Longships became known generally as dragons.) The sagas had been accurate in
their accounts of "great ships," the largest class of Viking warship.
The passage of a millennium has not dimmed the pride Scandinavians feel for the Viking
longships. Their vital role in seaborne raiding, which is the meaning of the Norse term
viking, assures them a prominent place in medieval history. Fleets of these long, narrow
ships attacked coasts from Northumberland to North Africa, carried pioneers to the British
Isles and Normandy, and made the Vikings the dominant sea power in Europe from about A.D.
800 to 1100, the Viking Age.
Although finds of various Viking ships and boats have been made since 1751--most
spectacularly in the royal burial mounds at Gokstad and Oseberg in Norway--the classic
longship itself proved elusive until 1935, when Danish archaeologists excavated a
chieftain's burial mound at Ladby. Only the shadow of a ship remained, with dark-stained
soil revealing the form of the hull. Iron spirals marked the crest of the dragon's head at
the prow, and seven long rows of iron rivets on either side still followed the lines of
the vanished planks. The Ladby ship was much narrower than the celebrated Norwegian ships
and looked quite unseaworthy: 20.6 meters long, only 3.2 wide amidships and a mere meter
from the keel to the top plank. Critics dismissed as implausible the accounts in the sagas
of much larger longships with the same extreme proportions.
Actual timbers of a longship were located in 1953 in Hedeby harbor, site of a prosperous
Viking emporium on the German border. Although the ship was not raised, public interest
ran so high that the diver who discovered it made a radio broadcast underwater; his
fascinated audience included 18-year-old Ole Crumlin-Pederson. By age 22, he had embarked
on a series of finds that exploded the timid theories of the skeptics and ultimately
involved him in the retrieval and study of every longship discovered since Ladby.
Peaceful burial mounds had yielded prior finds, but Crumlin-Pedersen specialized in
disaster sites. Between 1957 and 1962 he was co-director of the team that recovered two
longships and three other Viking ships from a blockade in a channel near Skuldelev, where
desperate Danish townsfolk in the 11th century had deliberately sunk the ships to create a
barricade against invaders. The bigger of the two Skuldelev longships, measuring 29
meters, met its end after making at least one successful voyage across the North Sea: its
wood was Irish oak, cut about 1060 near the Viking stronghold of Dublin. Both ships in
fact showed many seasons of wear, evidence that longships were more seaworthy than some
scholars had thought.
In 1979 Crumlin-Pedersen fulfilled a dream of his youth by leading the excavation of the
Hedeby longship. It proved to have perished as a fire ship, a vessel intentionally set
ablaze as an offensive weapon, during an attack on the town in about 1000. Here, too, the
wood was remarkable: local oak cut from 300-year-old trees in lengths exceeding 10 meters
without a knot or blemish.
