Eurydice

In Greek mythology, the wife of Orpheus. She was a dryad, or forest nymph, and died from a snake-bite while fleeing from Aristaeus. Orpheus attempted to fetch her back from the realm of the dead, but was unsuccessful.

Descending to Hades, the underworld, he charmed Pluto with his lyre playing and persuaded the god to allow Eurydice to follow him back to the upper world, on condition that he did not look behind him; he turned at the gates and Eurydice was lost. They were reunited after his death,and his lyre became the constellation Lyra.
