Cupid is often portrayed on Valentine’s Day cards as a naked cherub launching arrows of love at unsuspecting lovers. But the Roman God Cupid has his roots in Greek mythology as the Greek god of love, Eros. Accounts of his birth vary; some say he is the son of Nyx and Erebus; others, of Aphrodite and Ares; still others suggest he is the son of Iris and Zephyrus or even Aphrodite and Zeus (who would have been both his father and grandfather).
According to the Greek Archaic poets, Eros was a handsome immortal played with the emotions of Gods and men, using golden arrows to incite love and leaden ones to sow aversion. It wasn’t until the Hellenistic period that he began to be portrayed as the mischievous, chubby child he’d become on Valentine’s Day cards.
