- "This encyclopedia covers the entirety of the Celtic world, both through time and across geography. Although emphasizing the areas where Celtic languages and traditions survive into the present, the work does not slight the reaches of the Celtic empire, which was the largest language and cultural group on earth prior to the rise of Rome. In some 1,500 articles, many representing original research by the finest Celtic scholars, the work covers the Celts from prehistory to the present, giving comprehensive treatment to all topics from myth to music, religion to rulers, literature to language, government to games, and all topics in between.
