Eros and Anteros. Hellenistic era. From the Wikipedia: In Greek mythology, Anteros (Greek: Ἀντέρως, Antérōs) was the god of requited love, literally "love returned" or "counter-love" and also the punisher of those who scorn love and the advances of others, or the avenger of unrequited love. Anteros was the son of Ares and Aphrodite in Greek mythology, given to his brother Eros, who was lonely, as a playmate, the rationale being that love must be answered if it is to prosper. Alternately, he was said to have arisen from the mutual love between Poseidon and Nerites. Physically, he is depicted as similar to Eros in every way, but with long hair and plumed butterfly wings. He has been described also as armed with either a golden club or arrows of lead.
Anteros, with Eros, was one of a host of winged love gods called Erotes, the ever-youthful winged gods of love, usually depicted as winged boys in the company of Aphrodite or her attendant goddesses.
