But mythology is a woof of many colours, in which the hues are shot and blended, so that the various races of supernatural beings are shaded off, and fade away almost imperceptibly into each other; and thus, even in heathen times, it must have been hard to say exactly where the Giant ended and the Troll began. But when Christianity came in, and heathendom fell, when the godlike race of the Æsir became evil demons instead of good genial powers, then all the objects of the old popular belief, whether Æsir, Giants, or Trolls, were mingled together in one superstition, as "no canny." They were all Trolls, all malignant; and thus it is that, in these Tales, the traditions about Odin and his underlings, about the Frost Giants, and about sorcerers and wizards, are confused and garbled; and all supernatural agency that plots man's ill is the work of Trolls, whether the agent be the arch-enemy himself, or giant, or witch, or wizard.

In "Tatterhood," p. 345, the Trolls are very near akin to the witches of the Middle Age. In other tales,
