The Greek writer Lucian ("ca." 125–after 180 AD) suggests that Pluto's love for his wife gave the ruler of the underworld a special sympathy or insight into lovers parted by death. In one of Lucian's "Dialogues of the Dead", Pluto questions Protesilaus, the first Greek hero killed in the Trojan War, who wishes to return to the world of the living. "You are then in love with life?" Pluto asks. "Such lovers we have here in plenty; but they love an object, which none of them can obtain." Protesilaus explains, like an Orpheus in reverse, that he has left behind a young bride whose memory even the Lethe's waters of forgetting have not erased from him. Pluto assures him that death will reunite them someday, but Protesilaus argues that Pluto himself should understand love and its impatience, and reminds the king of his grant to Orpheus and to Alcestis, who took her husband's place in death and then was permitted at the insistence of Heracles to return to him. When Persephone intercedes for the dead warrior, Pluto grants the request at once, though allowing only one day for the reunion.
