About this book
About this Mythology Themes mythology guide
Gods turn into bulls and swans, the cursed become wolves, seals slip off their skins to dance as women. This is the complete guide to shapeshifting in world mythology.
To change your shape is to break the deepest rule there is, that a thing is what it is. Mythology is full of the rule being broken. Gods turn into bulls and swans to seduce mortals; witches and sorcerers take the form of hares and cats; the dead and the cursed become wolves; seals slip off their skins to dance as women on the shore. The shapeshifter unsettles us because it dissolves the line between human and animal, self and other, and that is exactly why every culture tells stories about it.
This is the complete guide to shapeshifting across world myth and folklore. The shape-changing gods, Zeus and his disguises, Proteus the old man of the sea, the Norse Loki who becomes a mare and gives birth; the werewolf and the skin-changer; the selkie of the northern seas; the fox-spirits of Japan and China; the witch in animal form; and the deep human fascination with the body that will not stay still.
The book gathers the shapeshifters across cultures, drawing on Homer, Ovid, the Eddas, the folklore collections and the Eastern sources, and every chapter cites where it comes from.
