According to an Aztec myth, the war god Huitzilopochtli sent a group of Mexica on a journey to establish the new center of the world. After some two hundred years of wandering, they saw an eagle resting on a cactus with its “wings stretched outward like the rays of the sun.” Taking the bird to be a divine sign that they had reached their destination, they “began to weep and dance about with joy and contentment.”
