Eos was the daughter of the Titans Hyperion and Theia: Hyperion, a bringer of light, the One Above, Who Travels High Above the Earth and Theia, The Divine, also called Euryphaessa, "wide-shining" and Aethra, "bright sky". Eos was the sister of Helios, god of the sun, and Selene, goddess of the moon, "who shine upon all that are on earth and upon the deathless gods who live in the wide heaven". The generation of Titans preceded all the familiar deities of Olympus who largely supplanted them. In some accounts, Eos's father was called Pallas.
The dawn goddess Eos was almost always described with rosy fingers or rosy forearms as she opened the gates of heaven for the Sun to rise. In Homer, her saffron-colored robe is embroidered or woven with flowers; rosy-fingered and with golden arms, she is pictured on Attic vases as a beautiful woman, crowned with a tiara or diadem and with the large white-feathered wings of a bird.
Now when Dawn in robe of saffron was hastening from the streams of Oceanus, to bring light to mortals and immortals, Thetis reached the ships with the armor that the god had given her.
But soon as early Dawn appeared, the rosy-fingered, then gathered the folk about the pyre of glorious Hector.
She is most often associated with her Homeric epithet "rosy-fingered" Eos Rhododactylos (Ancient Greek: ), but Homer also calls her Eos Erigeneia:
That brightest of stars appeared, Eosphoros, that most often heralds the light of early-rising Dawn (Eos Erigeneia).
Near the end of the Odyssey, Athena, wanting to buy Odysseus some time with his wife Penelope after they have reunited with each other, orders Eos not to yoke her two horses, thus delaying the coming of the new day:
And rose-fingered Dawn would have shone for the weepers had not bright-eyed goddess Athena thought of other things. She checked the long night in its passage, and further, held golden-throned Dawn over Ocean and didn't let her yoke her swift-footed horses, that bring daylight to men, Lampus and Phaethon, the colts that carry Dawn.
And after these Erigeneia ["Early-born"] bore the star Eosphoros ("Dawn-bringer"), and the gleaming stars with which heaven is crowned.
Thus Eos, preceded by the Morning Star, is seen as the genetrix of all the stars and planets; her tears are considered to have created the morning dew, personified as Ersa or Herse.
Eos played a small role in the battle of the giants against the gods; when the earth goddess Gaia learned of a prophecy that the giants would perish at the hand of a mortal, Gaia sought to find a herb that would protect them; thus Zeus ordered Eos, as well as her siblings Selene (Moon) and Helios (Sun) not to shine, and harvested all of the plant for himself, denying Gaia the chance to make the giants indestructible.
Eos is presented as a goddess who fell in love several times. According to Pseudo-Apollodorus, it was the jealous Aphrodite who cursed her to be perpetually in love and have an insatiable sexual desire because once had Eos lain with Aphrodite's sweetheart Ares, the god of war. This caused her to abduct a number of handsome young men.
In the Odyssey, Calypso complains to Hermes about the male gods taking many mortal women as lovers, but not allowing goddesses to do the same. She brings up as example Eos's love for the hunter Orion, who was killed by Artemis in Ortygia. Apollodorus also mentions Eos's love for Orion, and adds that she brought him to Delos, where he met Artemis.
The good-looking Cleitus was snatched and made immortal by her.
Eos fell in love with and abducted Tithonus, a handsome prince from Troy. She went with a request to Zeus, asking him to make Tithonus immortal for her sake. Zeus agreed and granted her wish, but Eos forgot to ask for eternal youth as well for her beloved. For a while, they two lived happily, until Tithonus' hair started turning grey, and Eos ceased to visit him in bed. But he kept aging, and was soon unable to even move. In the end, Eos locked him up in a chamber, where he withered away, forever a helpless old man. Out of pity, she turned him into a cicada.
The abduction of Cephalus had special appeal for an Athenian audience because Cephalus was a local boy, and so this myth element appeared frequently in Attic vase-paintings and was exported with them. In the literary myths, Eos snatched Cephalus against his will when he was hunting and took him to Syria. Although Cephalus was already married to Procris, Eos bore him three sons, including Phaethon and Hesperus, but he then began pining for Procris, causing a disgruntled Eos to return him to Procris, but not before sowing the seeds of doubt in his mind, telling him that it was highly unlikely that Procris had stayed faithful to him this entire time. Cephalus, troubled by her words, asked Eos to change his form into that of a stranger, in order to secretly test Procris's love for him. Cephalus, disguised, propositioned Procris, who at first declined but eventually gave in. He was hurt by her betrayal, and she left him in shame, but eventually they got back together. This time however it was Procris's turn to doubt her husband's fidelity; while hunting, he would often call upon the breeze ('Aura' in Latin, sounding similar to Eos's Roman equivalent Aurora) to refresh the body. Upon hearing that, Procris followed and spied on him. Cephalus, mistaking her for some wild animal, threw his spear at her, killing his wife.
The second-century CE traveller Pausanias knew of the story of Cephalus's abduction too, though he calls Eos by the name of Hemera, goddess of day.
Eos and the slain Memnon on an Attic red-figure cup, ca. 490-480 BCE, the so-called "Memnon Pietà" found at Capua (Louvre).
According to Hesiod, by her lover Tithonus, Eos had two sons, Memnon and Emathion. Memnon fought among the Trojans in the Trojan War and fought against Achilles. Pausanias mentions images of Thetis, the mother of Achilles, and Eos begging Zeus on behalf of their sons. In the end, it was Achilles who triumphed and slew Memnon in battle. Mourning greatly over the death of her son, Eos made the light of her brother, Helios the god of the sun, to fade, and begged Nyx, the goddess of the night, to come out earlier, so she could be able to freely steal her son's body undetected by the armies. After his death, Eos asked Zeus to make her son immortal, and he granted her wish. Her image with the dead Memnon across her knees, like Thetis with the dead Achilles are icons that inspired the Christian Pietà.[dubious – discuss]
Eos's team of horses pull her chariot across the sky and are named in the Odyssey as "Firebright" and "Daybright". Quintus described her exulting in her heart over the radiant horses (Lampus and Phaëton) that drew her chariot, amidst the bright-haired Horae, the feminine Hours, climbing the arc of heaven and scattering sparks of fire.
Cult and temples
There are no known temples, shrines, or altars to Eos. However, Ovid seems to allude to the existence of at least two shrines of Eos, as he describes them in plural, albeit few, in the lines:
[Eos addresses Zeus :] 'Least I may be of all the goddesses the golden heavens hold - in all the world my shrines are rarest.
Ovid may therefore have known of at least two such shrines.
Among the Etruscans, the generative dawn-goddess was Thesan. Depictions of the dawn-goddess with a young lover became popular in Etruria in the fifth century, probably inspired by imported Greek vase-painting. Though Etruscans preferred to show the goddess as a nurturer (Kourotrophos) rather than an abductor of young men, the late Archaic sculptural acroterion from Etruscan Cære, now in Berlin, showing the goddess in archaic running pose adapted from the Greeks, and bearing a boy in her arms, has commonly been identified as Eos and Cephalus. On an Etruscan mirror Thesan is shown carrying off a young man, whose name is inscribed as Tinthu.
The Roman equivalent of Eos is Aurora, also a cognate showing the characteristic Latinrhotacism. Dawn became associated in Roman cult with Matuta, later known as Mater Matuta. She was also associated with the sea harbors and ports, and had a temple on the Forum Boarium. On June 11, the Matralia was celebrated at that temple in honor of Mater Matuta; this festival was only for women during their first marriage.
^Lycophron calls her by an archaic name, Tito (the Titaness). Kerenyi observes that Tito shares a linguistic origin with Eos's lover Tithonus, which belonged to an older, pre-Greek language. (Kerenyi 1951:199 note 637)
