The Legend of Martha Brae

The legend tells of an old Arawak witch, who lived on the bank of the River Matibereon.

Having heard tales of the Arawak gold, Spanish treasure hunters captured the witch to lead them to the treasure.

Pretending to comply she led them into a cave,  then suddenly disappeared.

Frightened, the Spaniards ran out of the cave but the river engulfed them.
The witch then changed the course of the river forever.

Passed on by mouth the legend still lives on.  Twisted translations produced the English version of river Matibereon:
