Eros, the Greek god of love and sexual desire (the word eros, which is found in the Iliad by Homer, is a common noun meaning sexual desire). He was also worshiped as a fertility god, believed to be a contemporary of the primeval Chaos, which makes Eros one of the oldest gods. In the Dionysian Mysteries Eros is referred to as "protagonus", the first born. But there are many variations to whom the parents of Eros really where. According to Aristophanes (Birds) he was born from Erebus and Nyx (Night); in later mythology Eros is the offspring of Aphrodite and Ares. Yet in the Theogony, the epic poem written by Hesiod, it mentions a typified Eros as being an attendant of Aphrodite, but not her son. Another legend says that he was the son of Iris and Zephyrus.
