The origin of the theory of light, darkness, water, fire, wind, thunder, earth and elements.

The theory of four elements (water, flame, atmosphere and land) comes from the ancient Greek philosophy system. Ancient Greek philosophers believed that everything was made up of these four elements, which corresponded to five regular cubes (there was also a corresponding element called ether, which was considered as the element that constituted the universe and stars, but it was not the mainstream view).

Later, it developed to mean that everything has the difference between density and temperature at the same time (density: atmosphere to land, temperature: flame to water)

Later, the view of alchemy was combined with the biblical worldview (or the Bible absorbed these two theories), and the pentagram theory came into being. The five corners of the five-pointed star refer to spirit, water, flame, atmosphere and land respectively. When the angle symbolizing the spirit indicates that the power of light rises, it indicates that the power of darkness falls.

The view that light and darkness are the foundation of the world is that human beings have a unified cognition before they have culture, and both of them exist in that myth system, so it is difficult to explain the earliest source. Even China's Taoist thought of Yin and He is one of them. )

The appearance of thunder element is unique to Nordic mythology. Strictly speaking, the earliest element of thunder should be called storm element. Later, the image of Raytheon was gradually strengthened in circulation, and finally Raytheon element and the famous shrine-Raytheon Sol were born.

In Roman times, China's five elements thought was introduced into Rome, and some people introduced the Nordic element of thunder, which decomposed the atmosphere in the original Greek four-element system into wind and thunder, and then tried to explain China's five elements thought (thunder corresponds to gold, wind corresponds to wood, and there is also a fairy sword).

Of course, this theory of five elements still can't explain the five elements. So far, many mysteries in the west are based on the theory of four elements, supplemented by two elements of light and darkness. Only by introducing chakras (geomantic omen and geographical circulation theory) and the five elements into the East can the five elements theory (not the pentagram theory) appear.
