After he abducted her, Zeus ordered him to return Persephone back to Demeter, her mother, but before she left the Underworld Hades gave her a pomegranate. When she ate the piece of fruit, it bound her to the Underworld forever. He then made her his bride and the queen of the Underworld. According to Walter Burkert, author of the book Greek Religion, "to be carried off by Hades and to celebrate marriage with Hades become common for metaphors for death, especially for girls" (Burkert 161). So did Persephone die when she was captured by the god Hades?.
As for the marriage between Hades and Persephone, not much information can be determined. They had no children, and because of this and the fact that the regions of the Underworld were removed from the activities which are mythology's primary subject matter, stories about the couple are pretty well limited to those growing out of the abduction already encountered (Barthell, Jr. 59). It is known that the relationship between the two at the beginning was bad, but their union was very peaceful despite the abduction and the rape. .
In his travels through the land of the shades, and when he abducted Persephone from earth, he used his eerie chariot drawn by four, immortal black horses of which Abastor was the leader" (Barthell, Jr. 58). Hades had several duties besides ruling over the people who were held in captivity in the Underworld. Hades owned herds of oxen either in his dark kingdom or on the island of Erytheia which were taking care of by his faithful herdsman Menoetes. That was until Heracles broke the ribs of Menoetes in a wrestling match (Barthell, Jr. 59). He is also assisted by several other demonic servants including Thanatos and Hypnos, the ferryman Charon, and the hell hound Cerberus (Hades). The helmet of Hades which made the wearer invisible was given to Hades by the god Hephaestus or by the Cyclopes after their delivery from the Underworld to fight against the Titans.
