Greek Mythology Hydra

Wiki info

While the age of gods often has been of more interest to contemporary students of myth, the Greek authors of the archaic and classical eras had a clear preference for the age of heroes, establishing a chronology and record of human accomplishments after the questions of how the world came into being were explained. For example, the heroic Iliad and Odyssey dwarfed the divine-focused Theogony and Homeric Hymns in both size and popularity. Under the influence of Homer the "hero cult" leads to a restructuring in spiritual life, expressed in the separation of the realm of the gods from the realm of the dead (heroes), of the Chthonic from the Olympian. In the Works and Days, Hesiod makes use of a scheme of Four Ages of Man (or Races): Golden, Silver, Bronze, and Iron. These races or ages are separate creations of the gods, the Golden Age belonging to the reign of Cronos, the subsequent races to the creation of Zeus. The presence of evil was explained by the myth of Pandora, when all of the best of human capabilities, save hope, had been spilled out of her overturned jar. In Metamorphoses, Ovid follows Hesiod's concept of the four ages.

The Lernaean Hydra was a monster in Greek mythology. It had many heads and every time someone would cut off one of them, two more heads would grow out of the stump. It was one of the offspring of Typhon  and Echidna , the father and mother of all monsters respectively. It lived in the lake Lerna in the region of Argolid in the Peloponnese.
