The Raven darkness. The use of the raven—the "devil bird"—also suggests this. This devil image is emphasized by the narrator's belief that the raven is "from the Night's Plutonian shore", or a messenger from the afterlife, referring to Pluto, the Roman god of the underworld (also known as Dis Pater in Roman mythology). A direct allusion to Satan also appears: "Whether Tempter sent, or whether tempest tossed thee here ashore..." Poe chose a raven as the central symbol in the story because he wanted a "non-reasoning" creature capable of speech. He decided on a raven, which he considered "equally capable of speech"
Orcus Orcus Orcus () was a god of the underworld, punisher of broken oaths in Italic and Roman mythology. As with Hades, the name of the god was also used for the underworld itself. In the later tradition, he was conflated with Dis Pater. Orcus was portrayed in paintings in Etruscan tombs as a hairy, bearded giant. A temple to Orcus may have existed on the Palatine Hill in Rome. It is likely that he was transliterated from the Greek daemon Horkos, the personification of Oaths and a son of Eris. The origins of Orcus may have lain in Etruscan religion.
