The Church of Dagon T-Shirt

"Dagon" is often not counted as one of Lovecraft's Cthulhu Mythos stories, but it is the first of Lovecraft's stories to introduce a Cthulhu Mythos element — the sea deity Dagon itself. The creature that appears in the story is often identified with the deity Dagon, but the creature is not identified by that name in the story "Dagon", and seems to be depicted as a typical member of his species, a worshipper rather than an object of worship. Nor is it likely that Lovecraft intends "Dagon" to be the name used by the deity's nonhuman worshippers; as Robert M. Price points out, "When Lovecraft wanted to convey something like the indigenous name of one of the Old Ones, he coined some unpronouncable jumble".
