H.P. Lovecraft's stories have a timeless quality due to the very nature of the horror he was conveying. Lovecraftian horror is about the sense of existential dread humans get when they realize that the universe is a lot bigger than they could ever imagine. It's a form of cosmic horror that focuses on entities so complex and timeless that humans cannot even fathom their natures.
