Legend of the northern lights

The word aurora comes from the Latin Ios. Legend has it that Ios is the embodiment of "dawn" in Greek mythology (actually referring to morning light and morning glow), the daughter of the Greek god Titan, the sister of the sun god and the moon goddess, and the mother of many stars such as the north wind and the evening star. It is said that Aurora is the wife of Orion. In works of art, Ios is said to be a young woman. She either walked quickly arm in arm with a young man, or flew out of the sea in a carriage driven by a flying horse. Sometimes she is portrayed as such a goddess, holding a pitcher, spreading her wings and offering morning dew to the world, just like Guanyin Bodhisattva in the Buddhist story of China, spreading nectar to the world.
