"EREBOS" In Greek mythology, Erebos/Erebus (/ˈɛrɪbəs/), (Ancient Greek: Ἔρεβος, Érebos, "deep darkness, shadow" or "covered"), was often conceived as a primordial deity, representing the personification of darkness; for instance, Hesiod's Theogony identifies him as one of the first five beings in existence, born of Chaos.
