Mythology - Greek - Iris

Iris was the goddess of the rainbow and a messenger of the gods, especially Hera. She was able to travel from the sky to the earth, using the rainbow as her pathway, with a pitcher in one hand to replenish the water in the clouds and a caduceus, a herald's wand, in the other, which proclaimed her a messenger from the gods. She also gathered water from the river Styx for sacred oaths. She was the daughter of the sea god Thaumas and the cloud nymph, Electra, and is depicted as a young woman with wings.
