The Seba library treats Eos in 7 passages, across 3 authors (including Gregory Nagy, Kerényi, Karl, Burkert, Walter).
The divine motive for abduction by Eos is thus both preservative and sexual.
Nagy argues that Eos's serial abductions of beautiful youths encode a structurally dual function — erotic desire fused with the impulse toward immortalization — parallel to Zeus's abduction of Ganymede.

the originally fused functions of mating with the consort and being reborn from the mother were split and divided between Aphrodite and Eos respectively.
Nagy uses comparative Vedic evidence to argue that Eos's original functions — solar consort and regenerative mother — were fragmented in Hesiodic tradition, leaving her as birth-mother of Phaethon rather than his divine mate.

when the words are 'incorrect,' as in the myth of Eos and Tithonos, then the immortalization is ruined by the failure of preservation.
Nagy identifies the Tithonos myth as the canonical negative paradigm of immortalization, in which Eos's request for eternal life without eternal youth condemns her beloved to a living death.

the goddess in question is not some derivative Dios thugatēr but Eos herself. The only surviving attestation of her taking a direct part in epic action is the Aithiopis, where she translates her dead son Memnon into a state of immortality.
Nagy establishes Eos's unique function in the Aithiopis as a divine agent of heroic immortalization, distinguishing her direct role from the derivative functions of other goddesses.

Eos's great love for handsome youths, whom she used to carry off by force, so greatly dominated the tales concerning her that it was even asserted that her continual passions were a punishment inflicted on her by Aphrodite.
Kerényi characterizes Eos as mythologically defined above all by her compulsive erotic pursuit of mortal men, a role he traces to a punitive narrative frame originating with Aphrodite.

Nagy demonstrates that the formulaic phrase applied to Ganymede's abduction by Zeus also governs Eos's abduction of Kleitos, establishing beauty as the mythological trigger for divine seizure and immortalization.

Eos, 17, 121
Burkert's index entry places Eos among the primary Greek deities without developing an extended analysis, confirming her canonical status in the Greek religious pantheon.
