Daughter of king Pelias of Iolcus (Volos) and wife of king Admetus of Pherae. The king was good friends with Apollo after the god had served him to make amends with Zeus, whose sons the cyclops he had killed, and on his deathbed Apollo made the moirae let Pelias live if someone elso would die in his place. Alcestis then volunteered immediately, only to be saved by Hercules later on.-Demeter
