One of the earliest of documented sightings of aerial phenomena took place on April 4, 1561 at dawn over Nuremberg, Germany. What was described as a war in the heavens, with a wide variety of craft ranging from spheres to spear-like cylinders to crosses and “plates”. 
The sky was apparently filled with the machines, clashing in battle for well over an hour.  The battle was such that a winner was perceived as well.  Spheroid UFOs were seen emerging from cylindrical ‘motherships’.  At the conclusion of the battle, it seems a magnificent, black, spear-like super-ship of some kind came upon the scene.  An ancient woodcut was created by Hans Glaser to document the event.
