Through Dawn, Sun and Moon

In Greek literature, Eos is presented as a daughter of the Titans Hyperion and Theia, the sister of Helios and Selene (the Moon). In rarer traditions, she is the daughter of the Titan Pallas. Each day she heralds the breaking of the new day and the arrival of Helios; although primarily associated with dawn and early morning, she is sometimes said to accompany him for the whole duration of his journey, and thus can also be seen near dusk. Her most common epithets in the Homeric epics are Rhododactylos, or "rosy-fingered", a reference to the sky's colours at daybreak, and Erigeneia, "early-born".

Eos also appears in Greek tradition as the mother, by Astraeus, of the Anemoi, the winds, as well as of several astral figures connected with the morning and evening sky. Like her Roman counterpart Aurora and the Rigvedic Ushas, she continues the name and character of an earlier Indo-European dawn goddess, Hausos.

A major group of myths concerns Eos's love for mortal men, whom she pursued and sometimes carried away in a manner more often associated with male gods and mortal women. In surviving tradition, this desire is explained as the work of Aphrodite, who cursed the goddess with passion for mortal men after Eos slept with Ares. Her most notable mortal lover is the Trojan prince Tithonus, for whom she secured immortality but not eternal youth, leading him to age forever. In another story, she carried off the Athenian Cephalus against his will, though she eventually let him return to his wife Procris.

Eos figures in many works of ancient literature and poetry, but despite her antiquity and Proto-Indo-European origins, there is little evidence of her having received extensive independent cult or being the centre of worship during classical times.

Etymology

The Proto-Greek form of Ἠώς / Ēṓs has been reconstructed as *ἀυhώς / auhṓs. It is cognate to the Vedic goddess Ushas, Lithuanian goddess Aušrinė, and Roman goddess Aurora (Old Latin Ausosa), all three of whom are also goddesses of the dawn. Meissner (2006) suggested an áwwɔ̄s > /aṷwɔ̄s/ > αὔως lengthening for Aeolic and */aṷwɔ̄s/ > *āwɔ̄s > *ǣwɔ̄s > /ǣɔ̄s/ for Attic-Ionic Greek.

Lycophron calls her by an archaic name, Tito, meaning "day" and perhaps etymologically linked to "Titan". Karl Kerenyi observes that Tito shares a linguistic origin with Eos's lover Tithonus, which belonged to an older, pre-Greek language.

In Greek dialects

In Mycenaean Greek her name is also attested in the form 𐀀𐀺𐀂𐀍 in Linear B, a-wo-i-jo (Āw(ʰ)oʰios; reconstructed *Ἀϝohιος), found in a tablet from Pylos; it has been interpreted as a shepherd's personal name related to "dawn", or dative form Āwōiōi.

Former proposals

Heinrich Wilhelm Stoll offered a different (now rejected) etymology for ἠὼς, linking it to the verb αὔω, meaning "to blow", "to breathe."
