Admetus

In Greek mythology, a king of Thessaly whose wife Alcestis sacrificed her life to save him, later rescued by Heracles.

From Greek mythology; the name Admetus (Ἄδμητος) derives from Greek roots meaning 'untamed' or 'unconquered.' The mythological tale became famous through Euripides' play 'Alcestis,' one of the earliest surviving Greek dramas.
