Mars (mythology)
Venus and Mars

The union of Venus and Mars held greater appeal for poets and philosophers, and the couple were a frequent subject of art. In Greek myth, the adultery of Ares and Aphrodite had been exposed to ridicule when her husband Hephaestus (whose Roman equivalent was Vulcan) caught them in the act by means of a magical snare. Although not originally part of the Roman tradition, in 217 BCE Venus and Mars were presented as a complementary pair in the lectisternium, a public banquet at which images of twelve major gods of the Roman state were presented on couches as if present and participating.

Scenes of Venus and Mars in Roman art often ignore the adulterous implications of their union, and take pleasure in the good-looking couple attended by Cupid or multiple Loves (amores). Some scenes may imply marriage, and the relationship was romanticized in funerary or domestic art in which husbands and wives had themselves portrayed as the passionate divine couple.

The uniting of deities representing Love and War lent itself to allegory, especially since the lovers were the parents of Concordia. The Renaissance philosopher Marsilio Ficino notes that "only Venus dominates Mars, and he never dominates her". In ancient Roman and Renaissance art, Mars is often shown disarmed and relaxed, or even sleeping, but the extramarital nature of their affair can also suggest that this peace is impermanent.
