Decoding Ptolemy's map re-dates German cities

A group of experts from Berlin Technical University's Department for Geodesy and Geoinformation Science have cracked a 2nd  century map of Germany created by Ptolemy, re-dating many of the country's cities by 1,000 years.

The scholars believe they may have new information on the cities east of the Rhine River, which were never occupied by the Romans. "The eastern German city that is now called Jena, for example, was called Bicurgium, while Essen was Navalia. Even the town of Fürstenwalde in eastern Germany appears to have existed 2,000 years ago. Its name then was Susudata, a word derived from the Germanic term susutin, or 'sow's wallow' -- suggesting that the city's skyline was perhaps less than imposing."
