Inhalt: Three of Europe's greatest rivers share the same geological cradle: one fertile patch of Alpine ice in the jagged heights of central Switzerland. Coursing down through the peaks, the Rhine, the Rhone and the Po gave birth to three different European cultures—German, French and Italian—as they flowed across the continent. From this shared geological cradle, these waterways have shaped the landscape, influenced the pattern of towns and cities, laid the foundation for economies and created an intricate network of transport, trade and agriculture. From the Romanesque buttresses and vines of Provence to the Wagnerian music of the Rhine and the artistic miracles of Lombardy, the heart of Western Europe—its languages, religion, philosophy, science, politics and art—has been nourished by these waters.
