Hydra Frequently Asked Questions and Useful Information for Travel

Who is Hydra in Greek mythology?

The Hydra is not a Greek god, but a multi-headed, serpent-like monster from Greek mythology, the child of the monstrous Typhon and Echidna, and a symbol of overwhelming and regenerating problems. It lived in the swamps of Lerna, breathed poisonous gas and had venomous blood. The hero Hercules battled the Hydra as one of his twelve labors, defeating it by cauterizing its necks with the help of his nephew, Iolaus, and burying its immortal head.

What does hydra mean?

In Greek mythology, a hydra is a many-headed serpent or monster that was slain by Hercules, and each head of which when cut off was replaced by two others. Figuratively, it can refer to a multifarious evil not to be overcome by a single effort.

How is a hydra killed?

The Greek mythical Lernaean Hydra is killed by Hercules by repeatedly cutting off its regenerating heads and then cauterizing the stumps with a torch to prevent two new heads from growing.
