Nemesis

Sources present variant genealogies and statuses. In Hesiodic and early tradition Nemesis appears as a pre-Olympian or early divine power linked to primordial figures (the Hesiodic tradition associates her with Night/Nyx in some lines), while other accounts place her functionally alongside Olympian justice—interacting with Zeus’s dispensation of justice. Later mythographic traditions and epic fragments (e.g., Cypria and later authors) include narrative episodes in which she is involved in the births and destinies of mortals (for example, variants making her the mother of Helen in some stories). These differing accounts reflect her dual character as an ancient force of cosmic ordering and an active agent in literary myth.

Classical iconography portrays Nemesis as a winged goddess. Attributes commonly associated with her in literary and art-historical descriptions include instruments of measurement or restraint (a measuring rod or tally stick, a bridle, scales) and occasionally instruments of enforcement (sources describe depictions of a whip or dagger). Early visual types sometimes resembled mother/earth/fertility goddesses (for example, affinities with Cybele, Rhea, Demeter, or Artemis in certain periods and local cult imagery).

Nemesis embodies distributive justice: she 'gives what is due' by balancing fortune and meting out consequences when proper measure is violated. She is described as the avenger of hubris—implacable and inexorable (epithets such as Adrasteia, 'one from whom there is no escape,' and Erinys are applied). Literary examples of her active role include orchestrating the fate of Narcissus (Ovid) and arranging vengeance in episodes related in Nonnus’ Dionysiaca; she is also presented in epic fragments and mythographic tradition as involved in events surrounding Helen’s origin in some variants (Cypria and later accounts). Over time she is sometimes associated with Tyche (Fortune) as a balancer to chance.
