Hercynian Forest

Central European forest of the Roman empire

The Hercynian Forest was an ancient and dense forest that stretched across Western Central Europe, from Northeastern France to the Carpathian Mountains, including most of Southern Germany, though its boundaries are a matter of debate. It formed the northern boundary of that part of Europe known to writers of Antiquity. The ancient sources are equivocal about how far east it extended. Many agree that the Black Forest, which extended east from the Rhine valley, formed the western side of the Hercynian, except, for example, Lucius of Tongeren. According to him, it included many massifs west of the Rhine.
