Turner, "Iä! Iä! Cthulhu Fhtagn!", Tales of the Cthulhu Mythos, p. viii. Turner writes: "Lovecraft's imaginary cosmogony was never a static system but rather a sort of aesthetic construct that remained ever adaptable to its creator's developing personality and altering interests... [T]here was never a rigid system that might be posthumously appropriated by the pasticheur... [T]he essence of the mythos lies not in a pantheon of imaginary deities nor in a cobwebby collection of forgotten tomes, but rather in a certain convincing cosmic attitude."
