Labor Two: The Hydra (continued)

To make matters worse, the Hydra's very breath was lethal. Even smelling its footprints was enough to kill an ordinary mortal. Fortunately, Heracles was no ordinary mortal. He sought out the monster in its lair and brought it out into the open with flaming arrows. But now the fight went in the Hydra's favor. It twined its many heads around the hero and tried to trip him up. It called on an ally, a huge crab that also lived in the swamp. The crab bit Heracles in the heel and further impeded his attack. Heracles was on the verge of failure when he remembered his nephew, Iolaus, the son of his twin brother Iphicles.
