The House on the Borderland (1908) by William Hope Hodgson is a landmark of cosmic horror. Two friends fishing in rural Ireland discover a ruined house and a mysterious manuscript. The document records the Recluse's terrifying experiences: he battles grotesque swine-like creatures emerging from a pit beneath his home, endures a supernatural siege on the house, and is hurled through time and space, witnessing the distant deaths of Earth, the sun, and the universe itself. Blending gothic haunted-house terror with vast cosmic visions, Hodgson's novel pioneered a unique fusion of horror and fantasy, profoundly influencing writers such as H.P. Lovecraft.
