HYDRA LERNAIA was a gigantic, nine-headed water snake, which haunted the swamps of Lerna. Herakles was sent to destroy her as one of his twelve labours, but for each of her heads that he decapitated, two more sprang forth. So with the help of Iolaos, he applied burning brands to the severed stumps, stopping the wounds and preventing regeneration. In the battle he also crushed a giant crab beneath his heel which had come to assist Hydra. The Hydra and the Crab were afterwards placed amongst the stars by Hera as the Constellations Hydra and Cancer.
HYDRA. This monster, like the lion, was the offspring of Typhon and Echidna, and was brought up by Hera. It ravaged the country of Lernae near Argos, and dwelt in a swamp near the well of Amymone: it was formidable by its nine heads, the middle of which was immortal. Heracles, with burning arrows, hunted up the monster, and with his club or a sickle he cut off its heads; but in the place of the head he cut off, two new ones grew forth each time, and a gigantic crab came to the assistance of the hydra, and wounded Heracles. However, with the assistance of his faithful servant Iolaus, he burned away the heads of the hydra, and buried the ninth or immortal one under a huge rock. Having thus conquered the monster, he poisoned his arrows with its bile, whence the wounds inflicted by them became incurable. Eurystheus declared the victory unlawful, as Heracles had won it with the aid of Iolaus.
Hydra was my first choice in what i wanted to model for my minor project but with time i will pick what i believe will be most suitable in terms for design and development.
