Mnemosyne — Classical Greek Myth Library

Iris, in Hesiod, is daughter of the sea-wonder Thaumas by Electra daughter of Oceanus—sister of the Harpies—and serves as the gods’ swift messenger, often linked with the rainbow’s arc between sky and earth. In the *Iliad* she is the poem’s working courier when Zeus (or Hera, or other gods) must send word without going themselves: she flies to Troy to bid the Trojans arm when the Achaeans muster; she fetches Helen to the wall; she restrains Athena and Hera from open war against Zeus’s will; she summons the winds for Patroclus’s pyre; she goes to Thetis and later escorts Priam’s ransom journey’s divine side by carrying Zeus’s command to Thetis and watching over the old king’s path. Unlike Hermes—who in Homer also guides and in the *Odyssey* leads souls—Iris in the *Iliad* is almost purely the spoken message made flesh: wind-footed, golden-winged in later diction, tireless between Olympus, Ida, and the plain. Hesiod further makes her the agent who fetches water of Styx when gods swear the great oath. Catalogue Iris briefly among cosmogonic-divine personnel so the Thaumasborn messenger is indexed before her many Trojan errands.
