Seafaring Vikings force out of Scandinavia and strike the new lands of Iceland , Greenland , andNorth America with no accessto modern sailing instrument . So how did they become so efficacious at navigating the harsh northerly seas ? Without a doubt , they used the stars , the Moon , and geographical landmark to coordinate , but what pass when the Sun is n’t shinny and you ’re sailing through Norse swarm and fog ? New research hints that their legendary seafaring skills could have been help by the use of crystal sunstones .
Two research worker have recently been working with computer models to visualize out just how effective these unusual crystals were at helping Vikings ocean trip from Norway to Greenland . The determination hint that the aventurine are not just superstitious nonsense of days run by – they might have been the secluded weapon system that secured the Vikings ' navigational prowess .
These inscrutable stonesare talk about in many of the Sagas of Iceland , a compendium of old stories about the events of ninth , 10th , and 11th century Iceland . According to these accounts , longboat sailors would hold these transparent crystals up to the sky against the stocky Arctic fog and heavy swarm . estimate by how the light polarise and the pattern of the beam of light , navigator could work out the direction of the Sun , even if it was obnubilate .
Some historian have thrown down on the sunstones because no strong-arm examples have ever been unearthed . However , this novel study highlights that the stones could have dramatically increase the chances of a Viking ship making it across the northern stretches of the Atlantic Ocean . It even hint that the Harlan Fisk Stone could explicate how the Vikings were so successful at seafaring and discovering new lands .
They simulated thousands of Viking ship voyages attempting to reach Greenland from Bergen in Norway with varying cloudiness at times of the summer solstice and leap equinox . Approximately 1,000 voyages is the number OF excursions that could have set sail to Greenland during the 300 year of the Viking era .
They discovered that Vikings could have made the journey with a 92 to 100 percent success charge per unit if they used the aventurine every three hours . If they used the sunstone every four hours or more , this success rate would drop to just 32 to 58 percent . Using the rock even less would have meant the navigation success drops to as humbled as 1 to 6 percent , look on the season .
“ We demo that this sailing method can function well under cloudy sky on a voyage with vary cloudiness if the piloting periodicity is little enough and is stagger symmetrically before and after the time tip of the real noon , ” the field reason out . “ Nobody know whether the Vikings really used this method . However , if they did , they could pilot with it on the dot . ”
