The Greek anchor states the rule through its one enforcement. Zeus orders Persephone returned; Pluto complies and cheats: "Pluto gave her a seed of a pomegranate to eat", "in order that she might not tarry long with her mother" [The Library (Bibliotheca), BOOK I, ch. V]. "Not foreseeing the consequence, she swallowed it" — and the seed is a contract: she is bound below for a third of every year, and because Ascalaphus witnessed the eating and told, "Demeter laid a heavy rock on him in Hades" [ibid.]. Frazer's long note on the page shows how widely the clause runs: the Egyptian dead who accepts the goddess's food "could return to earth no more"; the Maori warning, "if you once eat food in this place, you can never more return to life"; the Scottish rule against fairy food — a world-survey inside our served text [ibid., editor's note]. Thompson's own apparatus ranges from Norse to Hawaii, wired nowhere else yet. The logic every version shares: eating is incorporation — take the other world into your body, and it has taken you. One seed outweighs Zeus's decree by a third of every year.
