Viking 'Sunstone' Evidence Found On Sixteenth-Century English Wreck

[PADemD]

"Ancient Viking mariners didn’t have GPS or even a magnetic compass, but they still managed to beat Christopher Columbus to America by nearly 500 years. While it’s possible to navigate by observing the position of the sun, just how did seafarers in the northern latitudes manage to find their way when the sky was cloudy?

"Icelandic sagas make mention of a "sunstone" that could be used to find the sun even when it was hidden, thereby guiding sailors safely even in dark and stormy hours. Now, new scientific research implies that the sunstone isn’t just a fable.

"Even when the sun is hidden behind clouds or just below the horizon, it's possible to pinpoint its location by detecting the polarization of light."

1. I always love it when things thought of as 'fable' turn out to be true

When I took mineralogy ages ago I recall talking about the properties of calcite and how the instructor believed it was the 'sunstone' talked about in viking stories. He even brought in a good specimen to demonstrate how he thought it worked.

I also love being able to show people that my ancestors were not dumb barbaric brutes.

2. I should have posted the title "Science Proves Woo" in GD

I think it would have gotten more attention.

Glad you liked the article.

The ancients were no dummies.
