Mythology | Iris
Iris was the ancient Greek goddess of the rainbow, connecting the gods above to mortals below as a messenger of the Olympian gods. She was often identified specifically as Hera’s (the queen of the gods) handmaiden and personal messenger. Since Iris’ father was a marine-god and her mother a cloud-nymph, she was also associated with the sea and 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. [x]
