Hesiod tells of the Hydra of Lerna
c. 700 BC Tradition
Around 700 BC the poet Hesiod is the first to write about the Hydra, the many-headed water serpent of the marshes of Lerna, killed by Heracles. In the later version of the story two heads grew back for every one he struck off, until his nephew Iolaos seared the stumps with fire. It is legend, not history, but it made Lerna famous throughout the ancient world.
Note: The date is that of the oldest written source. The myth itself is older and cannot be dated.
