A la recherche de l'ancien nom de la Marne et autres cours d'eau

the long version

Foreword by Gerard Taverdet. It is likely that a river of the importance of the Marne did not wait for the Celtic invasion to receive a designation. Hence the question: what was the original name of the river? A major research in hydronymy and toponymy is issued here: indoeuropean, preindoeuropean, analysis of hydronymic basins across France, including Saone, Oise, Yonne, Norman basins, rivers in Ar-and Ol-and others. Large repertoire of old names. Rich information for a regional, a historian or a toponymist!
