Eurydice

From the Greek Εὐρυδίκη (Eurydike) meaning "wide justice", derived from εὐρύς (eurys) meaning "wide" and δίκη (dike) meaning "justice, custom, order". In Greek myth she was the wife of Orpheus. Her husband tried to rescue her from Hades, but he failed when he disobeyed the condition that he not look back upon her on their way out.
