It doesn't really need repeating, but Neil MacGregor's Radio 4 show Germany: Memories of a Nation is superlative on many levels. It is both pleasurable and essential listening. Although the focus of the series is the past six hundred years, I wanted to flag up a couple of episodes. "Fairy Tales and Forests" explains how forests fit into the German psyche and frames the debate with the Battle of Teutoburg Forest and the Brothers Grimm. The episode can be downloaded here. Then there is the episode "The Walhalla: Hall of Heroes" for a discussion about how Arminius/Hermann fits into the heroic national consiousness. That episode can be downloaded here.
