Unter Zee Kulten

Unter Zee Kulten is a fictional book invented by Carl Jacobi, part of a set of books mentioned in his story "The Aquarium" (1962) that deal with the mysteries of the sea. Jacobi says of it that "all copies...had supposedly been destroyed in the seventeenth century," but a pirated version of it still exists.
The other eldritch aquatic books named by Jacobi are Hydrophinnae and Dwellers in the Depths; all three texts are frequently mentioned together by Brian Lumley to indicate an unwholesome interest in oceanic secrets, in such stories as "The Cypress Shell," "Rising with Surtsey", "Dagon's Bell", "De Marigny's Clock", "Lord of the Worms", and "The House of the Temple".
Don Webb's story "The Sound of a Door Opening" involves two pranksters creating a hoax about a film called Unterzee Kulten, supposedly directed by George Pabst and released by UPA. The perpetrators are told that there really was a film by that name, based on a book called Das Geheimnis Der Unterzeerunen, written by Guido Von List and released in Vienna in 1908.
