Sun Compass

Definition

A sun compass is a navigational tool that uses the position of the sun in the sky to determine directions. This ancient device allowed navigators, particularly the Vikings, to find their way across open waters by tracking the sun's movement throughout the day, making it essential for maritime exploration and trade routes.

5 Must Know Facts For Your Next Test

1. The sun compass operates based on the principle that the sun rises in the east and sets in the west, moving through the sky in a predictable arc.
2. Vikings would often use a horizontal disk with a gnomon (a vertical stick) placed in the center to cast a shadow, helping them determine cardinal directions.
3. This tool was particularly useful during long sea voyages where landmarks were absent and conditions could change rapidly due to weather.
4. Evidence suggests that sun compasses were used extensively during Viking explorations, contributing to their ability to navigate to places like Greenland and North America.
5. Some archeological findings have indicated that Vikings may have created sun compasses that were adjustable for different latitudes, showing their advanced understanding of navigation.

Review Questions

• How did the use of the sun compass influence Viking navigation techniques during their maritime journeys?
  • The use of the sun compass significantly enhanced Viking navigation techniques by providing a reliable method for determining direction over long distances at sea. It allowed them to venture into open waters without reliance on landmarks, which was crucial when exploring new territories. By accurately tracking the sun’s position, Vikings could maintain their intended course, enabling successful voyages to distant lands such as Greenland and North America.
• Evaluate how the implementation of the sun compass impacted Viking maritime trade routes compared to other navigation methods available at the time.
  • The implementation of the sun compass allowed Vikings to navigate with greater precision than many other contemporary methods, which often relied on dead reckoning or following coastal routes. This new navigational capability expanded their maritime trade routes significantly, facilitating trade with regions further away and increasing economic exchanges. By being able to travel directly across open waters, Vikings accessed new markets and resources, leading to a flourishing trading economy.
