Alcestis

Latinized form of Greek Ἄλκηστις (Alkestis), derived from ἀλκηστής (alkestes) meaning "brave, valiant", a derivative of ἀλκή (alke) meaning "strength, prowess". In Greek mythology she was the wife of King Admetus. She offered to die in place of her husband, though she was eventually rescued from the underworld by Herakles. This story was told by the Greek playwright Euripides in his 5th-century BC tragedy Alcestis.
