The Greeks lived much in the open air, and they loved to watch the fleecy clouds float lazily across the blue heavens, or at night to see the bright, golden stars shine down upon them like friendly eyes. They believed that Juno was goddess of the heavens when they were calm and peaceful, as Jupiter was god of the storm cloud and of the thunderbolt.

Whenever they saw the radiant rainbow, they said, “There is the glowing Iris, the messenger of Juno, carrying some message from the sky to the earth.” They thought that Iris had shining wings of various colors, and that while she stayed upon earth, you could see her path in the heavens marked by the many-colored rainbow.
