…there was an Androgyne.
Indo-European cosmogony assumes that it (=he+she) existed in the primal nothingness (void, vacuum, oblivion…) and somehow split into Heaven and Earth (male and female, Father and Mother), thus giving birth to the world.
In fact, this belief is quite similar to what scientists actually think about the very beginning of everything. In certain physical models there is an initial absolute vacuum (with no time and space). At some point the vacuum collapses – a phase transition occurs – and kaboom! a “globe of fire” appears and starts to expand rapidly, creating space and time. It keeps growing and cooling until it splits into Energy and Matter (it seems that Latin mater stands for “mother” for good reason), thus giving birth to the world.
As you see – when it comes to the very beginning – science is not very far from pure mythology… It’s just some other words but the pattern remains the same. I would even risk a statement that the scheme of world creation from mythology is so deeply engraved within our Indo-European minds, that the so-called “western” scientists just couldn’t make up anything different!
Check the Encyclopaedia to learn more about the concept of androgynism which is common for all the Indo-European mythologies. Art by Alice Ferox, click “continue reading” for the non cropped image (watch it full screen for details!) and the whole entry.
More thoughts about cosmogony will arrive later. In the meantime you might also want to read about Ymir.
