Mythology plays a very important part in establishing the culture and world in fantasy novels. It is often the basis for the magic system, the religious beliefs, and the antagonist. There’s often an influence by gods or other supernatural beings, and the amount of power could be limitless.
In science fiction, mythology is quite different. It may not even be present. In Star Wars, the Force is almost mythological. In Dune, the religions have changed so much that they’ve become the new mythology. In the Hyperion Cantos, the Shrike is often regarded as a myth or legend. Much of the time, mythology draws on older religions, but not always.
In my Ariadne universe, there will be a couple cases of new religions and mythologies that develop. One has an origin that will change over time as the centuries pass, but it’s an interesting mix of elemental and old Earth religion, mainly Christianity. The Christianity part fades away, but the basis is there. In the other case, Earth itself becomes almost mythological, and it’s revered by a large portion of the population.
What are some other examples of mythology in science fiction? Let me know in the comments below.
