Iris
The swift-footed goddess of the rainbow who served as Hera's personal messenger, bridging heaven and earth with her arc of colour.
The Myth of Iris
Iris was the daughter of the sea-god Thaumas and the Oceanid Electra, and sister of the Harpies. She served as the messenger of the gods in the Iliad, particularly of Hera — just as Hermes served Zeus. Her path between heaven and earth was the rainbow, which the Greeks saw not as a meteorological phenomenon but as the visible trace of a goddess in flight. She was golden-winged and swift as the wind, carrying commands from Olympus to the farthest corners of the earth and even to the depths of the sea and the Underworld. In the Iliad, it is Iris who informs Achilles of Patroclus's death and who carries Hera's commands to the wind gods. She also fetched water from the River Styx when the gods needed to swear their most binding oath — the oath of the Styx, which even Zeus could not break. Her name may connect to the Greek eirein (to speak or announce), making her the goddess who articulates divine will in a bridge of light.
