Cyane

In Greek mythology, Cyane or Kyane (Κυανῆ "dark blue" in Greek) was a nymph who tried to prevent Hades from abducting Persephone, her playmate. Upon failure, she dissolved away in tears and melted into her pool. In a slightly different version, Cyane was the Naiad (i.e. the fresh-water nymph) of a spring in the Sicilian town of Syracuse. After witnessing Hades's abduction of the goddess Persephone and trying to prevent it, she was turned to liquid by Hades.
