Final answer:
Hesiod's Theogony does not focus deeply on Eros, but he is one of the primordial beings symbolizing attraction and procreation. The Orphic myths, however, provide a different narrative that involves Eros in a more complex cosmogony and theogony, contrasting with Hesiod's account.
Eros is not prominently featured or detailed in Hesiod's Theogony, thus the question seems to refer to a broader context involving ancient Greek mythology and literature, rather than specific content from Hesiod's work. The figure of Eros in Greek mythology overall is complex and occurs in numerous texts and myths. In Theogony, which is primarily a genealogy of the gods, Hesiod mentions Eros as one of the primordial beings, symbolizing the fundamental force of attraction and procreation that binds the cosmos.
In contrast, the Orphic myths tend to emphasize a different cosmogony and theogony that involve a more elaborate role for Eros. The Orphic traditions, which are separate and often at odds with Hesiod's accounts, include intricate stories of the creation of the universe and the origins of gods and humans. The Orphic Theogony presents a complex narrative involving the role of Zeus and other deities in the creation and transformation of the cosmos and humanity, with various divine myths such as the of Persephone, the punishment of the Titans, and the creation of mankind from their ashes, indicating a mix of theogony with anthropogonic narratives.
Therefore, while Eros is a significant figure within the broader spectrum of Greek mythology, his portrayal and significance vary across different texts and should not be narrowly associated with the content of Hesiod's Theogony alone.
