iris

In Greek mythology, Iris was the daughter of Thaumas and the ocean nymph Electra and one of the Oceanids (according to Hesiod), the personification of the rainbow and messenger of the gods. As the rainbow unites Earth and heaven, Iris was the messenger of the gods to men; in this capacity she was mentioned frequently in the Iliad, but never in the Odyssey, where Hermes takes her place. She is married to Zephyrus, god of the west wind.

Iris is represented as a youthful virgin, with wings of gold, who hurries with the swiftness of the wind from one end of the world to the other, into the depths of the sea and the underworld. She is especially the messenger of Hera, and is associated with Hermes, whose caduceus or staff she often holds. By command of Zeus she carries a ewer of water from the Styx, with which she puts to sleep all who perjure themselves. Her attributes are the caduceus and a vase. She is also represented as supplying the clouds with the water needed to deluge the world. Iris is the personal messenger of Hera, queen of the gods and is Hera's go-between from Mount Olympus to the mortal world.

The word iridescence is derived in part from the name of this goddess.


Ah healing, and the nemisis of the perjurer
yes quite right!
