Iris was chosen by the gods to carry water from a river, to Mount Olympus for the gods to swear by. Since she could move with the speed of the wind, Iris acted also like the messenger of the gods. She took the orders of Zeus and the other deities and appeared in front of the people in a human form in order to reveal the orders to them. Furthermore, Iris was a goddess of the sea and the sky.
• Many Greeks believed that the rainbow’s arc, connecting clouds and the sea, represented Iris’ path or journey as she went from her home above to collect water from the sea in order to replenish clouds that had rained.
