Did the Vikings invent the sun compass?
The Uunartoq disc is an artifact discovered in the ruins of a Norse Greenland homestead. It is widely believed to be an early Norse sun compass.
Did Vikings use sun dials?
It is accepted by the scientific community that Viking navigators used primitive sun-compasses  to guide their ships during the season of bright Nordic nights. Sun-compasses are close relatives to sundials.
Why was the Viking sun compass important?
This could have allowed Vikings to navigate around the clock, to use the artefact dial as a Sun compass during long parts of the day and to use skylight polarization patterns in the twilight period.
How did the Vikings navigate without the sun?
Viking sagas may have been more truthful than we realised. Crystal “sunstones” could have helped Viking sailors to navigate even when cloud or fog hid the sun. Vikings navigated using sundials calibrated to show the direction of the North Pole.
What is Viking Sunstone?
The Norse sagas mention a mysterious “sunstone” used for navigation. Now a team of scientists claims that the sunstones could have been calcite crystals and that Vikings could have used them to get highly accurate compass readings even when the sun was hidden.
Is the Sunstone from Vikings real?
Ancient lore has suggested that the Vikings used special crystals to find their way under less-than-sunny skies. Though none of these so-called “sunstones” have ever been found at Viking archaeological sites, a crystal uncovered in a British shipwreck could help prove they did indeed exist.

Do Sun boards work?
The sun stone was thought to be a fraud, but later findings make it clear that it actually worked. North Star: Viking navigators relied on the North Star, also known as Polestar or Polaris, to chart the direction of their routes at night.
How did the Viking sun compass work?
The Vikings probably used a sun compass. A sun sompass always shows the correct direction. This comprises a vertical pointer on a horizontal surface, on which the shadow of the pointer, the so-called gnomon, is drawn through the day.
How does the sunstone work?
Here’s how it works: If you put a dot on top of the crystal and look through it from below, two dots will appear. “Then you rotate the crystal until the two points have exactly the same intensity or darkness. At that angle, the upward-facing surface indicates the direction of the Sun,” Ropars explained by phone.

How to channel your inner Viking with a sun compass?
When they did, they made a compass using just a block of wood, a nail, a pencil, and the sun! You too can channel your inner viking, by making a Sun Compass! The compass will only last for a few days, since the earth is constantly moving around the sun, and changing its position, causing the shadow to now be in a new orientation.
Did the Vikings have a compass?
Figure 12: Sketch of the Viking sun shadow board (Credit: M. Nielbock, own work). The magnetic compass was unknown in Europe during the Viking age. And it would have been quite useless for them anyway, because the magnetic field of the Earth is far from homogeneous.
How does a sun compass work?
The sun compass is a true compass, which works for a particular time of the year at a particular latitude. It consists of a vertical stick, which throws a shadow on an underlay. The compass can be calculated mathematically, but it can also be made by noting the passage of the sun throughout the day.
How do you draw a Viking compass?
Draw a straight line from that point to the base of the nail. That will be your North-South line (as a Viking, living in the Northern hemisphere, North is pointing away from the nail. If you are making your sun compass in the Southern hemisphere, North is pointing towards the nail, and you must be the most utterly-lost Viking in history).
