Spirit derives from Germany.
This "spiritual phenomenon" was observed and described by a natural scientist in 1780 at the Brocken peak in the Harz Mountains in Germany.
A Brocken Spectre can only be seen when specific conditions are met: The sun must be directly at one's back and there must be many suspended water droplets in the air where the Spectre's glory appears. Sunlight enters the water droplets and reflects off the back of the droplets and the light comes back towards the sun and the observer.
