The Cthulhu Mythos encompasses the shared elements, characters, settings, and themes found in the works of H. P. Lovecraft and associated horror fiction writers. Together, they form the mythos that authors writing in the Lovecraftian milieu have used—and continue to use—to craft their stories. The term itself was coined by the writer August Derleth. Although this legendarium is also sometimes called the Lovecraft Mythos, most notably by the Lovecraft scholar S. T. Joshi, it has long since moved beyond Lovecraft's original conception.
