Joshua Whatmough's monumental study of the dialects of Ancient Gaul heretofore has been available only in copies made from microfilm at considerable cost. This new edition makes readily accessible a book of first importance to Keltic scholarship. The work is organized by geographic areas and covers the Alpine Regions, Gallia Narbonensis, Aquitania, Lugdunensis, Belgica, Germania Inferior, Germania Superior, and the Agri Decumates with the Upper Rhine and Danube. There are several appendices, and Whatmough's “Keltika,” originally published in 1944, is included as an introduction.
