The Greek god of love and sexual desire. He was one first gods to emerge from primeval Chaos and is considered to be one of the eldest gods. In more recent mythology, Eros is the son of Aphrodite and Ares, and one of the younger deities. He is represented as a playful, winged boy with a bow and arrows. He wounds both gods and men with his unerring and irresistible arrows of desire. His arrows come in two sets: golden arrows with dove feathers for love, and leaden arrows with owl feathers for indifference. Eros' brother is Anteros ("returner of love") and his wife is the mortal Psyche.

In the Dionysian Mysteries, Eros is the most ancient deity and referred to as Protagonus ("the first-born") who emerged from the cosmic egg of Nyx, the goddess of night. According to Plato, Eros is the striving of mankind to the pure, the good, the beautiful. Eros' Roman counterpart is Amor / Cupid.
