A 20th-century successor to Edgar Allan Poe as the master of “weird fiction,” Howard Phillips Lovecraft once wrote, “The oldest and strongest emotion of mankind is fear, and the oldest and strongest kind of fear is fear of the unknown.” In the novellas and stories that he published in such pulp magazines as Weird Tales and Astounding Stories—and in the work that remained unpublished until after his death, including some of his best writing—Lovecraft adapted the conventions of horror stories and science fiction to express an intensely personal vision, cosmic in its ramifications and fearsome in its pessimistic view of human destiny.
