The Lernaean Hydra or Hydra of Lerna (
According to Hesiod, the Hydra was the offspring of Typhon and Echidna.[3] It had poisonous breath and blood so virulent that even its scent was deadly.[4] The Hydra possessed many heads, the exact number of which varies according to the source. Later versions of the Hydra story add a regeneration feature to the monster: for every head chopped off, the Hydra would regrow two heads.[5] Heracles required the assistance of his nephew Iolaus to cut off all of the monster's heads and burn the neck using a sword and fire.[6]
Development of the myth
The oldest extant Hydra narrative appears in Hesiod's
Like the initial number of heads, the monster's capacity to regenerate lost heads varies with time and author. The first mention of this ability of the Hydra occurs with
The Hydra had many parallels in
Second Labor of Heracles

Eurystheus, the king of the Tiryns, sent Heracles (or Hercules) to slay the Hydra, which Hera had raised just to slay Heracles. Upon reaching the swamp near Lake Lerna, where the Hydra dwelt, Heracles covered his mouth and nose with a cloth to protect himself from the poisonous fumes. He shot flaming arrows into the Hydra's lair, the spring of Amymone, a deep cave from which it emerged only to terrorize neighboring villages.[9] He then confronted the Hydra, wielding either a harvesting sickle (according to some early vase-paintings), a sword, or his famed club. Heracles then attempted to cut off the Hydra's heads but each time that he did so, one or two more heads (depending on the source) would grow back in its place. The Hydra was invulnerable as long as it retained at least one head.
The struggle is described by the mythographer
The alternate version of this myth is that after cutting off one head he then dipped his sword in its neck and used its venom to burn each head so it could not grow back. Hera, upset that Heracles had slain the beast she raised to kill him, placed it in the dark blue vault of the sky as the constellation Hydra. She then turned the crab into the constellation Cancer.
Heracles would later use arrows dipped in the Hydra's poisonous blood to kill other foes during his remaining labors, such as
