What connects together Lucifer, Loki, and Prometheus?

And other so called Luciferian deities I havent heard of yet, I guess. I’ve gone through a good dive online about the similairitss of not only Lucifer and Prometheus (the book named that way. About the treatment of Satan in Milton’s poem) but also Loki the mischief god. I’d like to know what you people with a deeper knowledge on traditional occultism could tell me about it.
