Anecdotes
Cthulhu was born from the pen of H.P. Lovecraft in the summer of 1926, but the text "The Call of Cthulhu" was not published until February 1928 in the pulp magazine *Weird Tales*. Lovecraft, little recognized in his lifetime, was paid by the page and remained virtually unknown until his death.
Lovecraft insisted that the name be unpronounceable by a human mouth. In his letters, he suggested an approximation like "Khlûl'-hloo," specifying that the true sounds exceeded the human vocal apparatus — a way of emphasizing the creature's radical strangeness.
The ritual phrase "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn" ("In his house at R'lyeh, dead Cthulhu waits dreaming") is one of the most famous sentences in weird fiction. Lovecraft invented it from scratch, with no real grammar.
The term "Cthulhu Mythos" is not Lovecraft's: it was coined by his friend August Derleth after 1937 to describe the shared universe born from these stories. Lovecraft encouraged other authors to reuse his creatures, creating a collective mythology.
Today Cthulhu is an icon of popular culture: plush toys, board games, role-playing games, and cameos in films. This posthumous fame contrasts sharply with the poverty in which Lovecraft died in 1937.
Primary Sources
The thing cannot be described — there is no language for such abysses of shrieking and immemorial chaos, for such a contradiction of all matter, force, and cosmic order.
Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn — "In his house at R'lyeh, dead Cthulhu waits dreaming."
The syllables were determined by a physical apparatus quite different from ours; the closest human approximation would be something like "Khlûl'-hloo".
