Howard Phillips Lovecraft, of Providence, Rhode Island, was an American author of horror, fantasy and science fiction. Lovecraft's major inspiration and invention was cosmic horror: life is incomprehensible to human minds and the universe is fundamentally alien. Those who genuinely reason, like his protagonists, gamble with sanity. Lovecraft has developed a cult following for his Cthulhu Mythos, a series of loosely interconnected fictions featuring a pantheon of human-nullifying entities, as well as the Necronomicon, a fictional grimoire of magical rites and forbidden lore. His works were deeply pessimistic and cynical, challenging the values of the Enlightenment, Romanticism and Christianity. Lovecraft's protagonists usually achieve the mirror-opposite of traditional gnosis and mysticism by momentarily glimpsing the horror of ultimate reality.
