Hydra was a monstrous nine-headed serpent that terrorized the region of Lerna

Hydra was a monstrous nine-headed serpent that terrorized the region of Lerna. Every time one of their heads was cut off, two new ones grew in their place. Herakles, as part of his Twelve Labors, was tasked with defeating the creature. With the help of his nephew Iolaus, he used fire to cauterize the wounds after cutting off each head, preventing them from regenerating. After a fierce battle, Herakles finalmente derrotou Hydra e enterrou sua cabeça imortal sob uma enorme rocha. As a tribute to this great battle, Zeus placed the image of Hydra in the sky as a constellation, symbolizing the fight against the impossible and the victory of courage over terror.
