Alcestis

Her life story was told by pseudo-Apollodorus in his Bibliotheca,[1] and a version of her death and return from the dead was also popularized in Euripides's tragedy Alcestis.

[2] Alcestis was the wife of Admetus by whom she bore a son, Eumelus, a participant in the siege of Troy, and a daughter, Perimele.

But in a sacrifice after the wedding, Admetus forgot to make the required offering to Artemis, therefore when he opened the marriage chamber he found his bed full of coiled snakes.

[5] Apollo again helped the newlywed king, this time by making the Fates drunk, extracting from them a promise that if anyone would want to die instead of Admetus, they would allow it.

[6] As a token of his appreciation for Admetus' hospitality,[7] Heracles rescued Alcestis from the underworld, shortly after fighting with Thanatos.
