*Photo courtesy of Horst Bierau, a photographer (also, scientist and new father) who grew up in Wolfshausen. I found Horst through the combined magic of Google and Flickr, and have enjoyed making his acquaintance this week. More good news, Wolfshausen is set just as I remembered it so the geography of the story so far makes sense (Full-size panorama of Wolfshausen here. The camera is placed in the widow Greulich's front yard, today's story begins in the draw at upper right.)
Horst was also kind enough to show me his excellent photo of this church (at right,) which was built in Wolfshausen in the 12th century and which makes it a little silly of Vater Karl to have decamped to Wolfshausen in 1519 and to have held his masses outdoors ever since. The old fool.
In any event, my appreciation to Herr Bierau for letting me use his photographs and my recommendation to you all to enjoy more of his photography at foto.bierau.net. Thanks, Horst.
