How does Heracles restore Alcestis to Admetus in Euripides’ Alcestis?

In the play Alcestis by the Greek dramatist Euripides, the hero Heracles restores Alcestis to her husband, Admetus, by intervening directly with the personification of death.12

After Alcestis voluntarily dies to spare her husband from his fated early death, Heracles arrives as a guest at the home of Admetus. Upon learning of the tragedy, Heracles travels to the grave of Alcestis to confront Thanatos, the god of death. Heracles successfully wrestles with Death, forcing him to relinquish his hold on Alcestis. Through this act of physical strength and intervention, Heracles rescues her and returns her to the relieved Admetus, allowing the play to conclude with a happy ending.31542
