H.P.Lovecraft is a popular horror author of the 1920's who is known for the Necronomicon mythos he created. Among the dieties called "the Old Ones", Shub-Niggurath is the never seen "Black Goat of the Wood, the Goat with a Thousand Young".
Cthulu, the most famous Lovecraft diety, is the inspiration for the Cthon character in Marvel Comics, and the Necronomicon corresponds to Marvel's "Darkhold" book.
In the novel Anansi Boys, by Alan Moore's friend Neil Gaiman, a character has thoughts very similar to the man at the end of this issue of SWAMP THING. The character muses about how using a gun to kill people makes him feel like part of an exclusive club.

Comments: The title may refer to the Ghost Dance religion of the Native Americans in the late 1880's. It was based on an ecstatic dance started by the prophet Wovoka, of the Paiute tribe, promoting peace and non-violence. Many members of the Ghost Dance were massacred at Wounded Knee.
Comments: This story is inspired by a real "haunted house": the Winchester Mansion, in San Jose California. Constructed by the widow of the heir of the Winchester Rifle Company, she ordered that the house be under construction night & day ("the sound of the hammers must never stop") to accommodate the ghosts of those killed by the rifles. The construction continued for 38 years until her death in 1922, resulting in 160 rooms covering over 6 acres. The house is a bizarre maze of dead ends and stairways to nowhere. There are windows in the floor and doors that open into brick walls. Many features in the house come in sets of 13. Click here to learn more.
Comments: Artist Steve Bissette wrote in Alan Moore: Portrait of an Extraordinary Gentleman that he thanks comic book creator Jim Wheelock for his ideas on this story. Wheelock's name appeared on a tombstone in SWAMP THING #42 and Bissette also named a company "Wheelock Neuro-Optics" in story he wrote for ST Annual #4.
COMMENT: In 2001, DC Comics collected/reprinted issues 43-50 in a trade book titled "Swamp Thing: A Murder of Crows" .
