Nemesis's origin dates back to the earliest days of Greek Mythology. She is the daughter of Nyx - The Primordial Goddess of Night and Aribus - The Primordial God of Darkness.
From the beginning Nemesis was seen as a powerful and untamed force, capable of keeping the cosmic order in balance. She was described as an ally of Zeus with the supreme leader using her to punish mortals who defied his authority.
Divine Retribution was a pivotal notion in the religion and culture of ancient Greece. The Greeks believed that the Gods had a stake in the lives of mortals, punishing those who disobeyed laws and violated the divine order. Divine retribution was a way to uphold the cosmic order and ensure the mortals respected divine authority.
The role of Goddess Nemesis was to exercise the same divine justice. In Greek mythology Nemesis was responsible for punishing those who were boastful and arrogant, often causing them to fall into disgrace or forcing them into a tide of bad luck. She was associated with revenge especially those who committed violent crimes or betrayed other people. The special punishment was meted out to those who deceived friends or family members.
Despite her negative reputation, Nemesis was also seen as a righteous Goddess. She was said to be impartial in her judgments and the punishments were considered appropriate and deserved, even when they seemed cruel. One of the best known myths associated with Nemesis is the story of Narcissus. He was an extremely beautiful young mortal who scorned the love and admiration of others. He eventually fell under the spell of Nemesis who made him fall in love with his image reflected in the water. Narcissus spent the rest of his days looking at his image and eventually died of sadness and loneliness. Narcissus's myth is often interpreted as an allegory for arrogance and vanity traits that the Goddess often punished.
The myth of Nemesis influenced the way the Greeks view justice and revenge. In ancient Greek society revenge was an essential form of justice. The idea that mortals should be punished for transgressions was widely accepted, but Nemesis added a supernatural sight to this idea suggesting that the Divine Forces were also involved in maintaining the cosmic order.
