At length Zeus sent Hermes with a petition to Pluto to restore Persephone to her mother. […] He and his wife were finally changed into serpents and sent by Zeus to the Elysian Plain. […] Ulysses was sent to discover his retreat, and did so by stratagem. […] The king to whom he was sent murdered him, and seized the treasures which had been sent with him. […] Zeus (Jupiter) sent Hermes (Mercury) to the hero, commanding him to embark without delay.
