Goddess of the rainbow, messenger of the gods (Eye-ris) Distinguishing features: Iris appears as a beautiful maiden with wings (rainbow-colored, naturally) carrying the symbolic staff of a herald like Hermes. When she’s not running around delivering messages, she serves nectar to Zeus and Hera in the throne room on Olympus, which is not as exciting but does let her rest her wings.
Now: Iris is constantly in demand to deliver Iris-messages for demigods. While this brings her a lot of supplemental income, she does wish Zeus would let her upgrade her network to 4G, since her coverage is spotty in many metropolitan areas.
Then: Iris was mostly the handmaiden to Hera. She never got much attention in the old myths, but everyone was always happy to see her. Much like a rainbow, she would show up where you least expected her and then disappear quietly. The colorful part of the eye, the Iris, is named after her. Not much of a tribute, but better than nothing, I guess.
Roman name: Iris or Arcus
