Just a little bit of trivia but Orpheus of Greek Mythology was the husband of a Dryad named Eurydice. Eurydice dies of a viper bite and so Orpheus ventured into the Underworld to bring her back, however he failed when he turned around and looked at her before they had finished exiting the entrance to the underworld.

Another bit of trivia, the story of Orpheus and Eurydice has parallels with the story of Izanagi and Izanami.
