When was the story by Lovecraft that the Xothic legend cycle is based on first published?
The Call of Cthulhu "The Call of Cthulhu" is a short story by the American writer H. P. Lovecraft. Written in the summer of 1926, it was first published in the pulp magazine "Weird Tales", in February 1928.
Books in the Cthulhu Mythos Many fictional works of arcane literature appear in H.P. Lovecraft's cycle of interconnected works often known as the Cthulhu Mythos. The main literary purpose of these works is to explain how characters within the tales come by occult or esoterica (knowledge that is unknown to the general populace). However, in some cases the works themselves serve as an important plot device. Thus, in Robert Bloch's tale "The Shambler from the Stars", a weird fiction writer seals his doom by casting a spell from the arcane book "De Vermis Mysteriis".
