Local indigenous legend has it that serpent god Boi, furious over a broken heart, created the falls by shattering the Iguazu riverâs flow to prevent the maiden Naipu from escaping in a canoe with her lover Taroba. The legend says the rainbows that grace the waters are the souls of Naipu and Taroba reuniting. (AP Photo/Jorge Saenz)
