This is a Victorian comparative folklore essay — likely by Charles Godfrey Leland — working in the tradition of ethnographic mythology that would culminate in Frazer's *Golden Bough*. Its central subject is the folk belief, documented across Norse sagas, Italian peasant practice, and German custom, that sleeping in a pigsty (especially one housing a pregnant sow) produces genuinely prophetic dreams. The author marshals evidence from the *Heimskringla*, a Tuscan Romagna fortune-teller's ritual incantation to Saint Anthony, and the saga of Earl Haakon hiding in a pigsty while his thrall dreamed of his own betrayal, to show the belief's geographic breadth and cultural persistence. The essay's distinctive scholarly move is tracing this folk practice back to classical antiquity: it argues that the pig-pen dream ritual is a survival of ancient incubation sleep in temples of Ceres and Demeter, where live pigs were ritually kept underground, and where worshippers slept to receive oracular dreams from the goddess. Running through the piece is a meditation on the pig's paradoxical symbolism — simultaneously a sign of death and darkness (the wild boar) and of fertility, truth-telling, and sacred oath (because of the sow's prodigious fecundity and the animal's use in Roman, Scandinavian, and German sworn oaths). Anyone interested in the survival of pagan religious practice in European folk superstition, comparative mythology, or the erotics of ancient ritual will find the argument genuinely suggestive, though the prose ranges freely and the text cuts off before its conclusion.
