Overview
In ancient Greek religion and mythology, Iris is a daughter of the gods Thaumas and Electra, the personification of the rainbow and messenger of the gods, a servant to the Olympians and especially Queen Hera. Iris appears in several stories carrying messages from and to the gods or running errands but has no unique mythology of her own. Similarly, very little to none of a historical cult and worship of Iris is attested in surviving records, with only a few traces surviving from the island of Delos. In ancient art, Iris is depicted as a winged young woman carrying a caduceus, the symbol of the messengers, and a pitcher of water for the gods. Iris was traditionally seen as the consort of Zephyrus, the god of the west wind and one of the four Anemoi, by whom she is the mother of Pothos in some versions.
Etymology
The ancient Greek noun means both the rainbow and the halo of the Moon. An inscription from Corinth provides evidence for an original form (wîris) with a digamma that was eventually dropped. The noun seems to be of pre-Greek origin. A Proto-Indo-European pre-form *uh2i-r-i- has been suggested, although Beekes finds it 'hard to motivate.'
Family
According to Hesiod's Theogony, Iris is the daughter of Thaumas and the Oceanid Electra and the sister of the Harpies: Arke and Ocypete. During the Titanomachy, Iris was the messenger of the Olympian gods while her sister Arke betrayed the Olympians and became the messenger of the gods' enemy, the Titans.
She is the goddess of the rainbow. She also serves nectar to the goddesses and gods to drink.
Zephyrus, who is the god of the west wind, is her consort. Together they had a son named Pothos, or alternatively they were the parents of Eros, the god of love, according to sixth century BC Greek lyric poet Alcaeus, though Eros is usually said to be the son of Ares and Aphrodite. According to the Dionysiaca of Nonnus, Iris' brother is Hydaspes.
