Mythopedia : Plasma Mythology
Mythopedia : Marinus Anthony van der Sluijs' site detailing prehistoric evidence of plasma discharges including petroglyphs and other traces.
From the website : "Our objective is to study historical information regarding the structure, workings and origins of nature, with special emphasis on transient events. As scientists now recognise plasma as the dominant state of matter in the universe, the subject is conveniently referred to as plasma mythology. This eye-catching term serves to distinguish the present approach from more traditional schools of 'nature mythology', that did not acknowledge the significant role of transient events in human traditions."
