Nemesis is the Goddess of retribution against evil, and She’s also responsible for dealing out ill fortune to those with excessively good fortune. She’s a daughter of Nyx, and regarded most commonly as a punishing Goddess. She keeps retinue with Thyche (good fortune) and Aedos (modesty).
Her symbols include an apple branch, a whip or lash, and a sword. I also consider Griffins sacred to Her because of this passage from
Nonnus, Dionysiaca:
A wheel turned itself round before the queen’s feet, signifying that she rolls all the proud from on high to the ground with the avenging wheel of justice, she the allvanquishing deity who turns the path of life. Round her throne flew a bird of vengeance, a Gryps (Griffin) flying with wings, or balancing himself on four feet, to go unbidden before the flying goddess and show that she herself traverses the four separate quarters of the world: highcrested men she bridles with her bit which none can shake off, such is the meaning of the image, and she rolls a haughty fellow about as it were with the whip of misery, like a self-rolling wheel.
