- Writer August Derleth, a contemporary correspondent of Lovecraft and co-creator of the Cthulhu Mythos, placed R'lyeh at 49°51′S 128°34′W. [Derleth, A. The Black Island (1952)]
The latter coordinates place the city approximately 5,100 nautical miles (9,400 km) from the actual island of Pohnpei (Ponape), the location of the fictional "Ponape Scripture". Both locations are close to the Pacific pole of inaccessibility (48°52.6′S 123°23.6′W), a point in the ocean farthest from any land mass.
