How Did Hercules Die? The demigod Hercules with stood many life-threatening events and monsters, but even he eventually died. This is how and what Hercules' part was in his own death. When Hercules was trying to take his bride Deianeira home, he had to cross the Evenus River. Nessus, a centaur, served as ferryman. First he rowed Hercules across and then, as he started to row Deianeira across, he tried to rape her. Hercules, justly enraged, drew one of his poisoned arrows and shot the centaur. Before he died, the centaur persuaded Deianira to take some of his blood to use as a love potion should Hercules ever cause her to worry. In time, Deianeira became suspicious of Hercules' interest in another woman, named Iole, so she smeared some of the carefully saved centaur blood on a tunic and gave it to Hercules, trusting that it would act as a love potion and return him to her.
Unfortunately, the centaur had lied. The blood contained not a love potion, but a powerful poison from the poison with which Hercules had tipped his arrows. It had come from the Lernean hydra.
When Hercules put on the tunic, it burned. He was in such excruciating pain that he wanted to die and had a funeral pyre built for himself. He then mounted it and had it lit. He died and went to the gods where he was reconciled with his tormentor, the queen of the gods, Hera. She allowed him to marry her daughter Hebe and live among the gods thereafter.
Demurer his wife, who couldn't cross a river so a centaur carried her across then kidnapped her and tried to rape her when Hercules shot him with a poisoned arrow, however before he died he whispered in her ear," If you want Hercules to stay faithful put my blood on a cloak and he shall remain yours." So when Hercules was away she did just that, but when he put the cloak on, which had the poison he shot the centaur with, his skin started to burn. He had some of his friends make him a pyre. When he died, he joined his father (Zeus) and married Hera's daughter Hebe.
