This innovation could have provided the Vikings with an alternative method to determine the sun’s position and maintain their course, even in challenging weather conditions.

The use of sunstones by Vikings for navigation remains a subject of ongoing debate among scholars. However, the discovery of calcite crystals on a sunken Elizabethan ship further strengthens the theory that Vikings may have indeed utilized these sunstones in their navigation endeavors. While the exact techniques and practices used by the Vikings with sunstones remain uncertain, the presence of calcite crystals in a maritime context lends credence to the possibility of their use in Viking navigation.

The calcite crystals acted as natural polarizing filters, allowing the Vikings to discern the position of the sun’s polarization even when it was not directly visible. By calibrating the crystals and observing the patterns of polarization, the Vikings could potentially estimate the sun’s position and use it as a reference point for calculating their course at sea.

The Sunstone Hypothesis

The sunstone hypothesis proposes that the Norsemen used calcite crystals, commonly referred to as sunstones, to navigate when the sun was hidden by clouds and other atmospheric conditions. These crystals have unique optical properties that allow them to detect polarized light, which occurs when light waves oscillate in a specific direction.

The Vikings would have calibrated their sunstones by exposing them to sunlight and noting the direction of maximum polarization. By comparing this direction to the sun’s known position during specific times of day, they could infer the sun’s location even when it was obscured from view.

Some experts argue that the use of sunstones would have been essential for the Vikings’ long-distance voyages, particularly in the Northern Atlantic regions where cloudy skies and low visibility were common. Others maintain that Viking navigation relied primarily on traditional methods, such as observing celestial bodies, landmarks, and natural phenomena.
