01Identity

Thanatos in Greek tradition

Thanatos came to claim Alcestis after she offered her life for Admetus. Heracles met him at the tomb and forced Death into a wrestling match, compelling him to yield and release Alcestis to her husband and family. Thanatos is the Greek personification of death and mortality, associated with the passage from life to death and the fate awaiting the dead. Sisyphus also bound him, temporarily stopping death among mortals until Ares freed him.

Thanatos Wrestles Heracles for Alcestis

Thanatos came to claim Alcestis, who had offered to die in place of her husband, Admetus, king of Pherae. Euripides’ Alcestis says that Admetus had been allowed to find a substitute when faced with early death. His aged parents refused to surrender their remaining days, but Alcestis accepted the sacrifice. She was seized by a mortal sickness as Admetus recovered, and she died in his arms.

Admetus consigned Alcestis to the tomb. Heracles then arrived at the palace while travelling towards one of his labours. Admetus respected the duties of hospitality and initially concealed his grief from his guest. In another account, Heracles blundered into the house during Alcestis’s funeral. When he learnt what had happened, he felt remorse for his tactless behaviour and gratitude for Admetus’s welcome.

Heracles went to the tomb and waited for Death to appear. When Thanatos came for Alcestis, Heracles sprang upon him and seized him. They wrestled, and Heracles held Death in his arms with such force that Thanatos could not break free. Heracles continued the struggle until Thanatos promised to surrender Alcestis.

Heracles then restored Alcestis to Admetus and returned her to her family. Some accounts describe the struggle as a rescue from the tomb. Another says that Heracles learnt what was about to happen before Thanatos appeared and resolved to prevent him from taking either Alcestis or Admetus.

Thanatos Is Bound by Sisyphus

Thanatos came to take Sisyphus to the Underworld, but Sisyphus seized him and bound him in chains. He disabled the god of death and kept him captive. While Thanatos remained imprisoned, nobody could die. Men continued living even after they had been beheaded or cut into pieces. This threatened Ares, whose interests depended on death, so he hurried to Sisyphus, freed Thanatos, and delivered Sisyphus into his hands. Sisyphus then died and was sent to the Underworld.

Before he descended, Sisyphus had instructed his wife, Merope, not to bury him. When he reached the palace of Hades, he went directly to Persephone. He told her that, as an unburied man, he had no right to remain among the dead. He claimed that he should have been left on the far side of the river Styx. He asked to return to the upper world, arrange his burial, and avenge the neglect shown to him. He promised to come back within three days.

Persephone believed him and granted his request. Once Sisyphus was again beneath the light of the sun, he abandoned his promise and refused to return. Hermes was eventually summoned and brought him back by force. Sisyphus was then condemned to roll a great stone up a hill in the Underworld. Each time he reached the summit, the stone rolled down again to the bottom, and he had to retrieve it and begin once more.

Merope was ashamed to be the only one of the Pleiades with a husband in the Underworld, and a criminal at that. She left her six sisters in the night sky and was never seen again.
