What happened
Glaser's broadsheet describes two blood-red arcs in the sun, then many balls, some blood-red and some dull black, standing in rows and squares around it. They appeared to fight, and many fell toward the horizon as if in smoke. The woodcut also shows crosses, tubes and a large black spear shape. The image was little known until Carl Jung reproduced it in his 1958 book on flying saucers. Jung saw it as a natural event with religious meaning laid over it.
