Apparently, the only Ancient myth involving a tree of life/knowledge and a serpent that portrays the serpent as evil is the Judeo-Christian one.
In the other mythologies, the serpent plays the part of the guide to the human seeking knowledge from the tree. Many quests involve the hero embarking on an adventure to eat from this Tree.
The Serpent/Tree motif is found in many cultures, from Ancient Egypt, China, India, Mesomerica and even in the Nordic legends. Its also found in Shamanic worldview and in the Celtic Druidism/paganism.
PS: i just realized that some MBTI sites call the INTJ type the "Promethean Temperament".
