The Cthulhu Mythos was H.P. Lovecraft's greatest contribution to supernatural literature: a series of stories that evoked cosmic awe and terror through their accounts of incomprehensibly alien monsters and their horrifying incursions into our world.
In the 1920s and '30s, H.P. Lovecraft pioneered a new type of fiction that fused elements of supernatural horror with the concepts of visionary science fiction.
