Fabled Sunstone Discovered In English Shipwreck


A team of French archaeologists believe they have found a sunstone, a strange crystal that was said to help mariners locate the sun even on overcast days.

Some of the medieval Norse Sagas mention this device. In “Rauðúlfs þáttr,” King Olaf asks the hero Sigurður to point out the sun in the middle of a snowstorm. Sigurður points to where it is behind the gray sky. To test him, the king had a follower “fetch the sunstone and held it up and saw where light radiated from the stone and thus directly verified Sigurður’s prediction.”

One recent study suggests the “sunstone” was a double-refracting crystal, which allows light through when the light is polarized in certain directions. They brighten or darken depending on the polarization of the light behind it. Clouds block the sun’s visible light but let through a concentration of polarized light that can be detected by the crystal as it’s moved around. Double-refracting crystals such as cordierite, tourmaline and calcite are common in Scandinavia.

Some scholars have expressed doubts about the sunstone’s existence because “Rauðúlfs þáttr” is a highly allegorical tale full of magical events.

Now it appears the tale may not be all that fantastic after all. Archaeologists from the University of Rennes have been studying finds from a British ship that sunk in 1592 near the island of Alderney in the English Channel. They found a rectangular block of Iceland spar calcite crystal, a type known for its double-refracting properties. The crystal was found next to a pair of dividers that may have been used for navigation.

The researchers suggest that their discovery shows the use of sunstones lasted well beyond the Viking era.

The team’s results appear in the latest issue of the “Proceedings of the Royal Society.”

Crystal Cruises Hobbit Experience Brings New Adventure To Sea

Crystal Cruises are always looking for unique experiences to stand out from the crowd and an upcoming New Zealand sailing is no exception. Bringing adventure from the big screen to cruise passengers, Crystal Cruises has a new dinner experience this December, on the “Hobbiton” set used for the Lord of the Rings trilogy and new prequel film.

Just days after “The Hobbit

opens worldwide, Crystal Symphony calls in Tauranga in the Bay of Plenty region of the North Island of New Zealand, home of the “Hobbiton” set used for the “Lord of the Rings” trilogy and new prequel film. On the December 20 sailing, Crystal Symphony guests can have a private, guided tour from Frodo and Bilbo Baggins’ Hobbit holes to the Brandywine Bridge, featuring local wine and beer and a traditional Kiwi barbeque served by wait staff in Lord of the Rings costume.

“We are always looking for unique, boutique ways for our guests to immerse themselves in a world different from their own,” said Crystal’s Vice-President, Land & Port Operations, John Stoll in a Popular Cruising report.A second “Lord of the Rings“-themed adventure is also offered on both cruises, visiting Edoras’ home, Mt. Potts Station and Lodge, and New Zealand’s Southern Alps from Christchurch.

The 16-day Christmas/New Year’s sailing voyage overnights in Auckland before sailing through Tauranga, Napier, Christchurch, Dunedin, Sydney (double overnight), Melbourne (overnight), and Dusky, Doubtful, and Milford Sounds.

“With ‘The Hobbit’ opening mid-December, this is an extraordinarily timely opportunity for Crystal guests to be transported to a place that many fantasy-fiction genre fans, movie buffs, as well as wine and foodies, and off-the-beaten-path travelers, from around the globe can only dream of visiting,” said Stoll. The Hobbiton dinner and village exploration fee is $265 per person.
