In Greek mythology, Nemesis is the goddess of divine retribution, embodying the principle of justice against evil deeds and the undeserved good fortune of individuals. She is often depicted as a formidable force, punishing those guilty of hubris, or excessive pride before the gods. Notably, Nemesis was impregnated by Zeus and is recognized as the mother of Helen of Troy and Clytemnestra, linking her to significant figures in Greek lore.

One of her most famous myths involves Narcissus, a youth renowned for his beauty and vanity. In this tale, Nemesis punishes Narcissus for his arrogance by leading him to a pool where he becomes entranced by his own reflection, ultimately falling in love with it. This self-obsession leads to his demise, illustrating Nemesis's role as the arbiter of justice against those who disregard others' affections.

In the story of Simanity, Nemesis is portrayed as the sister of Aphrodite, who, consumed by jealousy, attempts to eliminate her by luring her into a forest to perish. However, Zeus finds  Nemesis alone and takes her to a cave where he subsequently impregnates her.
