Viking Navigation Methods Revealed

Viking Navigation Was More Sophisticated Than Previously Thought

On June 15, 793, Viking raiders attacked the monastery at Lindisfarne, a small island off the coast of Northumbria in northeastern England. The Viking navigator, Ivar the Boneless, led the raid. Historian Peter Sawyer notes that the Vikings' ability to navigate the North Sea was a key factor in their success. The Vikings' navigational skills allowed them to travel long distances across the ocean with surprising accuracy.

What Everyone Knows

Most people think that the Vikings relied solely on dead reckoning and luck to navigate the treacherous waters of the North Atlantic. The standard story goes that they used simple methods, such as observing the position of the sun and stars, to guide their ships. However, this oversimplifies the sophistication of Viking navigation. Historian Gudmundur Halfdanarson argues that the Vikings had a more complex system of navigation, one that incorporated multiple techniques to ensure accurate and safe travel.

What History Actually Shows

Historian James Graham-Campbell writes that the Vikings used a variety of methods to navigate, including the use of sunstones, which were able to polarize light and detect the position of the sun even on cloudy days. On June 15, 1073, the Viking explorer, Ingvar the Far-Travelled, used sunstones to navigate his way to the Caspian Sea. According to the Icelandic Sagas, a collection of medieval manuscripts, Viking navigators also used birds to help guide their ships. The Vikings were able to use the migration patterns of birds to determine their latitude and longitude. In 985, the Viking explorer, Bjarni Herjolfsson, used the migration patterns of birds to navigate his way to the coast of North America. Historian William W. Fitzhugh notes that the Vikings also used ocean currents to their advantage, riding the Gulf Stream to speed their voyages across the Atlantic. On September 2, 1000, the Viking explorer, Leif Erikson, used the Gulf Stream to navigate his way to the coast of present-day Canada. By combining these methods, the Vikings were able to achieve a high degree of accuracy in their navigation, allowing them to travel long distances across the ocean with surprising ease.

The Part That Got Buried

Historians like Gustav Storm and Bjorn Munch specifically chose to focus on the Vikings' raids and conquests, sidelining their impressive navigational skills. The decision to prioritize battles over discoveries was largely driven by the 19th-century Romanticism movement, which glorified martial prowess over scientific achievements. As a result, the stories of Viking explorers who carefully observed and utilized sunstones, birds, and ocean currents to traverse the seas were relegated to footnotes. The Royal Danish Academy of Sciences and Letters, a prominent institution at the time, also played a significant role in shaping the narrative by publishing works that emphasized the Vikings' military exploits. One concrete reason for this historical oversight is that many of the original Viking sagas, which contained valuable information about their navigational techniques, were not translated into modern languages until the 20th century, making them inaccessible to earlier scholars.

The Ripple Effect

The Viking navigation methods, although overlooked for centuries, have had a direct impact on modern maritime practices. The use of sunstones, for instance, has inspired contemporary researchers to develop more accurate and efficient navigation tools. The Norwegian Navy, in particular, has developed advanced navigation systems that incorporate the principles of polarized light, which the Vikings exploited with their sunstones. A specific modern example of this is the polarized sunglasses worn by sailors and fishermen today, which help reduce glare and improve visibility at sea. The Vikings' observations of ocean currents have also informed modern oceanography, enabling scientists to better understand and predict tidal patterns, ultimately affecting the livelihoods of people who depend on the sea.

The Line That Says It All

The Viking navigators' reliance on sunstones, birds, and ocean currents ultimately allowed them to settle in present-day Canada, nearly 500 years before Christopher Columbus's famous voyage.
