Yolngu people see the constellation of Orion as a canoe. They tell the story of three brothers who went fishing, and one of them ate a fish that was forbidden under their law. Seeing this, the Sun blew the three brothers and their canoe up into the sky. The three stars in the constellation's centre, which form Orion's Belt in Western mythology, are the three brothers. The Orion Nebula above them is the forbidden fish, and the bright stars Betelgeuse and Rigel are the front and back of the canoe. In this example, the astronomical legend has a clear message about a moral that people would follow on Earth. Aboriginal myths such as these are often focused around moral lessons, such as reminders of whether it is alright to eat certain types of food.
