Frank Belknap Long was an early contributor to the Cthulhu mythos with stories like “The Eye above the Mantel.” His work includes “The Hounds of Tindalos,” which explores the idea of freeing the mind through hallucinogens, and “The Space-Eaters,” which features a character based on H. P. Lovecraft.

Long’s stories often utilize the ocean as a setting, as seen in “The Ocean Leech” and “Second Night Out,” which involve sea-faring vessels encountering demons. Other works, such as “Dark Awakening” and “The Cottage Tenant,” focus on psychological probing and family dynamics.

Long also explores archeological themes in tales like “The Dog-Eared God,” “The Were-Snake,” and “A Visitor from Egypt,” which reimagine the history behind ancient treasures, sacrificial altars, mummified remains, and ritualistic practices.
