Heracles and his nephew Iolaus set out on their chariot to hunt and kill the Lernean Hydra. This quest was given to Heracles by King Eurystheus as punishment for the killing of his wife and kids in blind rage.
FETCH A DRY BRANCH IOLAUS
Heracles left Iolaus at the entrance of the great Hydra's den guarding the horses. In caution Heracles pulled back the bow he only could propelled arrows to The Hydra's cave and home.
The Hero's arrow woke up and intrigued the Hydra's attention.The Hydra crept out and with no hesitation Heracles swung at the closest head of this mystifying beast . With the might of Heracles the head flew off and pummeled to the ground. With two more in its place
Heracles kept swinging and swinging knocking heads one by one but it did nothing to the invincible, absorbent beast. With Heracles wit that sword, he summoned his nephew for assistance. Iolaus came to help his valiant uncle. Heracles kept demolishing heads with the might of a thousand gods in one when the heads were shriveled and weak Iolaus would use a dry branch on fire to sear the gaping hole so the Hyrda couldn't grow its heads.
Heracles defeated the Hydra after long hours of taking head one by one and searing the necks closed so they can't grow back. Heracles disposed of the immortal god like head by burying under a large stone one like the sky that Atlas carries on his back. Heracles set the stone on the last head and sealed the mighty serpent away forever.
After the serpent was alsin Heracles scavenged the acid like poison that belonged to ydra and dipped his arrows in this fatal venomous blood. When Heracles returned to King Eurysthyus the labor did not count his reasoning was Heracles was helped on this task and did not complete alone therefore it did not count.
