توضیحاتی در مورد کتاب به زبان اصلی :

As MGMs hit show Vikings on the History Channel follows the adventures of Ragnar Lothbrok and his brother Rollo, TV Historian Ashley Cowie unearths a rare Viking sea chart beneath Rosslyn Chapel in Scotland. Identifying important seats of power in the Vikings Nordic empire, it indicates a land far to the west of Britain. Is this chart the earliest representation of North America ever discovered?
Hidden in a chamber beneath Rosslyn Chapel in Scotland, TV Historian Ashley Cowie discovered a unique group of symbols and spent ten years exhaustively deciphering their meaning. After presenting his research at the International Science Festival his discovery was tested by professional scientists at Bradford University who confirmed that he had discovered an extraordinarily rare Viking sea chart.
Rosslyn Chapel was built in the 15th century by Sir William St Clair, a direct descendant of the powerful Viking Rollo who became Duke of Normandy. After exploring the St Clairs Norse heritage, this highly graphical book deciphers the layers of navigational information encoded into the chart revealing it was constructed following the cartographic methods established by the ancient Greek mathematician Ptolemy around 150 AD.
Not only does the chart reveal an ancient prime meridian lying dormant in the northern Scottish landscapes, but it also identifies several Viking power bases, including North America, which the Viking’s colonised around 1000 CE, five hundred years before Columbus set sail.
Considering the chart is carved on a 12th century wall, it might be the oldest cartographic reference to North America ever discovered opening up a fresh and exciting volume in the history of cartography and oceanic navigation.
