Strange Maps : Europe's divides

from StrangeMaps, October06 :

An interesting look at the religions and language groups that are elements of division (and union) in Europe. The mapmaker wanted to make a point by indicating three ‘core areas’ where a certain language group and religion overlap - resulting in an area that is Germanic+Protestant, another one that’s Slavic+Orthodox and one that is Romance+Catholic.

added references :

• Germanic Languages - The largest Germanic languages are English and German (map)
  
• Romance Languages - comprised of all languages that descended from Latin, the language of the Roman Empire. (map)
• Slavic Languages - closely related languages of the Slavic peoples - speakers in most of Eastern Europe, in much of the Balkans, in parts of Central Europe, and in the northern part of Asia. (map)
