Language Map of Europe

As Neatorama says of this language map of Europe:

Languages correspond only imprecisely with political borders, which are designated by the superimposed red lines.

The English version of this map was created by Postmann Michael in 2007 […] and there are continuing doubts regarding the accuracy of some of the language borders.

I am reminded of this equally wonderful graphic depicting the evolution of the Indo-European family of languages.
