Hydra

12 questions · Mythology

The Hydra is a many-headed serpent monster of Greek mythology that dwelt in the swamps of Lerna. Its terrible peculiarity: cut off one head, and two new ones grew back at once. Killing the Hydra was one of the twelve labours of the hero Heracles. He solved the problem by having his nephew immediately burn the neck stumps so no new heads could grow. The one immortal head he buried under a rock. To this day the „Hydra“ is a byword for a problem that keeps sprouting new offshoots as soon as one is dealt with. The fight in the swamp of Lerna was the second of the twelve labours and nearly a defeat: only when his nephew Iolaus seared the neck stumps of the nine heads was the regrowth stopped; the giant crab Hera sent to help ended as a constellation. The Hydra herself now stands in the sky too, as the most extended constellation of all and in the water her name lives on in the tiny freshwater hydra, which really does regrow like the monster. Good to know: If one cut off a head of the many-headed Hydra, two new ones grew back at once.
