FolkloreThe Brocken
The highest point of the Harz, where German tradition has witches gathering on Walpurgis Night — Goethe sent Faust there. The mountain gave its name to an optical effect: the Brocken spectre, the observer's own vast shadow cast on cloud below with a rainbow halo round the head. The effect is real and explicable, and probably lies behind a share of the stories of encounters at the summit.
