Etymologists and wordsmiths will take particular interest in a new set of maps going on sale in time for Christmas. The Atlas of True Names replaces the traditional names of the world's cities, countries, rivers and mountains with new ones to reflect their origins and literal meaning. The Great Land of the Tattooed (Great Britain), now features such cities as Hillfort (London), Bear Guard Home (Birmingham), Choked Pool (Liverpool) and Slopecastle (Edinburgh).
