Gluskap
North American Indian Mythology. Cottie Burland, Hamlyn Publishing, 1965.
Two brothers lived at the beginning of time. Gluskap represented righteousness. He made the plains, food plants, animals and humans. Malsum represented destruction. He made rocks, thickets and poisonous animals. Malsum tried to find magic to kill his brother, Gluskap. He asked Gluskap "what is your weakness, what would kill you." Unsuspecting of Malsum's evil intention, Gluskap replied "an owl feather." To this Malsum mistakenly admitted that only a fern root would kill him. One night Malsum took the feather of an owl's wing and used it in place of an arrowhead to kill his brother. Gluskap fell to his death, but he summoned his own magic and was reborn again. Believing that it was Malsum who tried to kill him, Gluskap went into the forest stream declaring that only a flowering reed would kill him. A toad heard this and hopped away. The toad searched for Malsum in the forest. When he found Malsum he asked him for the power to fly in exchange for his secret. Malsum refused, for a toad with wings is foolish. In anger and humiliation, the toad sought revenge and returned to Gluskap to warn him of the danger. Gluskap plucked a large-rooted stem. With it he struck down Malsum and his evil magic into the earth. Malsum did not have the power to be reborn like Gluskap. Instead he became a vindictive wolf. Left in peace Gloskap was able to finish creating the earth from his mother's body.
