What Circumstances of Hercules death?

Hercules, a hero from Greek mythology, met his death due to a tragic series of events involving a poisoned robe. The robe, given to him by his wife Deianira, was imbued with the venom of the centaur Nessus, whom Hercules had killed. As he wore the robe, the poison caused excruciating pain, leading Hercules to build his own funeral pyre. Ultimately, he ascended to Mount Olympus after his death, where he was granted immortality among the gods.
