Of the other Argonauts, Orpheus went to Thessaly, and there taught and softened the people much by his music.  He married a fair maiden named Eurydice, with whom he lived happily and peacefully, till she was bitten by a venomous serpent and died.  Orpheus was so wretched that he set forth to try to bring her back from Tartarus.  He went with nothing but his lyre, and his music was so sweet that Cerberus stood listening, and let him pass, and all the torments of the Danaids, Sisyphus and all the rest, ceased while he was playing.  His song even brought tears into Pluto’s eyes, and Proserpine, who guarded the female dead, gave him leave to take back Eurydice to the light of day, provided he did not once look back as he led her out of Tartarus.
