While we don't have written versions from that time period, these stories were passed down through generations by bards and storytellers. They were eventually written down in works like:
* The Homeric epics: The Iliad and the Odyssey, attributed to Homer, are among the oldest surviving works of Greek literature. While Homer's exact dates are unknown, these poems likely developed over centuries and were finally written down around the 8th century BC.
* The Hesiodic poems: The Theogony and Works and Days are attributed to Hesiod, a poet thought to have lived around the 8th century BC. These works deal with mythology and agriculture.
* Lyric poetry: The works of Sappho, Pindar, and Alcman represent a diverse range of lyric poetry, including love poems, hymns, and odes, dating back to the 7th and 6th centuries BC.
It's important to remember that oral tradition played a crucial role in shaping these stories for centuries before they were written down.
Even the works we have now likely represent a blend of different versions and interpretations that were passed down through generations.
