On April 14, 1561, Nuremberg’s residents witnessed a baffling aerial battle. The sky filled with orbs, crosses, cylinders, and hundreds of blue, blood-red, and black spheres, discs, and pipes.
A black arrow-shaped object also appeared, seeming to come out of the sun. The objects battled for about an hour, and most crashed beyond the city limit, sending black smoke into the air from the wrecks.
After this spectacle, artist Hans Glaser engraved a 10” x 14.5” wooden plank and wrote a text documenting what witnesses reported about the incident. This work is archived in the prints and drawings collection at the Zentralbibliothek Zurich in Switzerland.
Religious propaganda of this era called sky events divine warnings. In the aftermath of the Nuremberg incident, such interpretations framed it as a merciful God’s effort to prompt repentance, urging people to beg for mercy and change their ways.
By contrast, today, the incident has sparked debate over whether the Bavarian sky witnessed an early extraterrestrial spaceship battle.
This incident was not isolated. In fact, Nuremberg was one of many 16th-century European reports of “strange sky sightings,” including the similar events of 1566 in Besel, Switzerland, and two others in 1580 and 1582.
Building on these historical reports, UFO enthusiasts and historians view the art and text as historical accounts of an aerial battle. They cite details of the cylinders, interpreted as mother ships, and the smaller spheres, interpreted as drones or scouts, as possible evidence of advanced technology.
Skeptics wondered if this was a complex atmospheric event, specifically a meteorological phenomenon called “parhelia” (or “Sun Dog”), which creates light artifacts around the sun.
Others speculated that a sun dog display could have happened first, followed shortly by a meteorite impact. Together, these events could explain both the aerial lights and the reported crash and smoke.
Alternatively, some speculations center on mass hallucination. For instance, one niche theory connects widespread ergot poisoning (from fungus on grain) to collective hallucinations.
Another theory proposes an illegal fireworks display, drawing on Vannocci Biringuccio’s “De La Pirtechnia” and other manuals from 1540 – Europe’s first book on metallurgy. The book outlines early rockets and fireworks, including chapters on preparing and using rockets in warfare and festivals.
This raises the question: “Could this Italian book have ended up in the hands of a Nuremberg resident eager to test its firework recipes?”
Psychoanalyst Carl Jung analyzed this event in his 1958 book, Flying Saucers: A Modern Myth of Things Seen in the Skies, stating that “while a natural phenomenon likely occurred, the witnesses’ descriptions were shaped by their collective unconscious and the religious/military imagery of the time.”
