Been thinking about the Dragon God recently, and I noticed a parallel to a mythological being from an entirely different culture

The Dragon God is associated with weather, water, rainbows (or colour at least), and created Gensokyo and perhaps the entire world

If it had visited a culture that wasn't familiar with dragons, but very familiar with snakes, they would assume it was a snake, a huge, rainbow snake

Australia is full of snakes, and in Aboriginal mythology, the world is said to have been created by an enormous rainbow serpent, associated with weather, water and creation

This isn't unique to Australia, many cultures around the world share similar myths

Rainbows and dragons just seem to be a universal theme in human culture, Christians, too, believe in dragons (or they used to) and believe rainbows are a sacred message from God

Maybe it's just "big snakes are cool and rainbows are pretty", but I think there's more too it than that
