A comparison of European folk tales shows that fairies
have certain characteristics in common. They live in palaces underneath the
ground, from which they emerge at twilight to dance in mystic circles. They are
ruled by kings and queens and are possessed of great wealth. Though usually
invisible, they may sometimes be seen, especially by people who have the
faculty of perceiving spirits. To mortals the fairies are generally hostile,
leading wanderers astray, often blighting crops and cattle, and shooting arrows
which carry disease and death. They are constantly on the watch to carry off
human beings to their realm. A prisoner must be released at the end of a
certain time, unless he tastes fairy food, in which event he can never return.
Children in cradles are frequently snatched away by the fairies, who leave,
instead, imps of their own called "changelings." A changeling may
always be recognized by its peevishness and backwardness in learning to walk
and speak. If well treated, the fairies will sometimes show their gratitude by
bestowing on their favorites health, wealth, and long life. Lucky the child who
can count on a "fairy god-mother."
GIANTS AND OGRES
Stories of giants are common in folk tales. Giants are
often represented as not only big but also stupid, and as easily overcome by
keen-witted human foes like "Jack the Giant-killer." It may be that
traditions of pre- historic peoples have sometimes given birth to legends of
giants. Another source of stories concerning them has been the discovery of
huge fossil bones, such as those of the mammoth or mastodon, which were
formerly supposed to be bones of gigantic men. The ogres, who sometimes figure
in folk tales, are giants with a taste for human flesh. They recall the
cannibals of the savage world.
