Erebus, in Greek religion, the god of a dark region of the underworld and the personification of darkness. Erebus is one of the primordial beings in the Greek creation myth. He is the son of Chaos, who is also the mother of Erebus’s wife, Nyx, the personification of night.
The standard cosmology of Greek myth comes from Hesiod’s Theogony, which describes a kind of genealogy of the gods. According to Hesiod, in the beginning of the universe there was Chaos, the formless abyss from which the form of the universe emerged. Chaos was joined by other primordial deities, including Gaea, the personification of the earth; Tartarus, the underworld in the depths of the earth; and Eros, the god of love. From Chaos sprang her children, Erebus and Nyx. These beings were usually portrayed as forces or phenomena rather than the more anthropomorphic gods of popular mythology.
Hesiod further claimed that Erebus and Nyx created Aether, the bright air, and Hemera, day. Nyx alone, however, was said to have produced Thanatos (death), Hypnos (sleep), the Moirai (Fates), Nemesis (retribution), and many other dark phenomena. Other writers, however, sometimes attributed these beings to both Nyx and Erebus. Erebus and Nyx’s children were largely abstract, as they were only lightly personified forces of nature. It was Gaea’s line that produced most of the well-known Olympian deities, including Zeus and Hera.
In his De natura deorum (On the Nature of Gods), the Roman statesman and scholar Cicero noted that the Greek philosopher Carneades attributed many children to Erebus and Nyx together. Once again they are mostly dreadful forces of nature. According to Cicero, Carneades claimed that, in addition to Light and Day, Erebus and Nyx were the progenitors of Love, Guile, Toil, Envy, Fate, Old Age, Death, Darkness, Misery, Lamentation, Fraud, and Obstinacy, among others.
Greek playwright Aristophanes proposed a different cosmology in his play Birds. In that work Chaos, Night, Erebus, and Tartarus were the first primordial entities, and “blackwinged Night laid a germless egg in the bosom of the infinite deeps of Erebus.” After ages pass, the egg hatches and Eros springs forth. Eros and Chaos then mate and produce birds. The theology of ancient Greece’s Orphic religion had a different role for Erebus. According to an Orphic tradition, Erebus was the brother of Chaos and Aether, who all sprang from Chronos, the personification of time.
Besides being the embodiment of darkness, Erebus was also the name applied to a dark region of the underworld that souls passed through on their way to Hades, the realm of the dead. Erebus was often used as a poetic synonym for Hades or Tartarus in literature, as when Homer refers to “the hound of loathed Hades” being brought out from Erebus.
Like many other figures from Greek myth, Erebus’s name has sometimes been borrowed in modern times. Notably, the southernmost active volcano known in the world is named Mount Erebus. Located in Antarctica, it was discovered by British polar explorer James Clark Ross, who commanded the Royal Navy’s explorations of the Antarctic in 1839–43. Ross’s expedition consisted of two ships, the HMS Terror and the HMS Erebus, from which Mount Erebus derived its name. Both ships were later lost after becoming trapped in ice during a failed expedition to discover the Northwest Passage.
