In classical mythology, Cupid (Latin Cupīdō [kʊˈpiːdoː], meaning "passionate desire") is the god of desire, erotic love, attraction and affection. He is often portrayed as the son of the love goddess Venus and the god of war Mars. He is also known in Latin as Amor ("Love"). His Greek counterpart is Eros. Although Eros is generally portrayed as a slender winged youth in Classical Greek art, during the Hellenistic period, he was increasingly portrayed as a chubby boy. During this time, his iconography acquired the bow and arrow that represent his source of power: a person, or even a deity, who is shot by Cupid's arrow is filled with uncontrollable desire. In myths, Cupid is a minor character who serves mostly to set the plot in motion. He is a main character only in the tale of Cupid and Psyche, when wounded by his own weapons, he experiences the ordeal of love. Although other extended stories are not told about him, his tradition is rich in poetic themes and visual scenarios, such as "Love conquers all" and the retaliatory punishment or torture of Cupid. His powers are similar, though not identical, to Kamadeva the Hindu god of human love.

In art, Cupid often appears in multiples as the Amores, or amorini in the later terminology of art history, the equivalent of the Greek erotes. Cupids are a frequent motif of both Roman art and later Western art of the classical tradition. In the 15th century, the iconography of Cupid starts to become indistinguishable from the putto.

Cupid continued to be a popular figure in the Middle Ages, when under Christian influence he often had a dual nature as Heavenly and Earthly love. In the Renaissance, a renewed interest in classical philosophy endowed him with complex allegorical meanings. In contemporary popular culture, Cupid is shown drawing his bow to inspire romantic love, often as an icon of Valentine's Day.

Venus (/ˈviːnəs/, Classical Latin: /ˈwɛnʊs/; genitive Veneris /ˈwɛnɛrɪs/)[a] is a Roman goddess, whose functions encompassed love, beauty, desire, sex, fertility, prosperity, and victory. In Roman mythology, she was the ancestor of the Roman people through her son, Aeneas, who survived the fall of Troy and fled to Italy. Julius Caesar claimed her as his ancestor. Venus was central to many religious festivals, and was revered in Roman religion under numerous cult titles.

The Romans adapted the myths and iconography of her Greek counterpart Aphrodite for Roman art and Latin literature. In the later classical tradition of the West, Venus became one of the most widely referenced deities of Greco-Roman mythology as the embodiment of love and sexuality. She is usually depicted nude in paintings.
