Louis Jean François Lagrenée - Mars and Venus, Allegory of Peace, 1770. Oil on canvas Mars, the Roman god of War, throws back the rich green bed curtains that frame the scene. As the drapery parts, the morning light spills in to reveal the form of the sleeping Venus, the Roman goddess of love. Mars gazes at her, utterly captivated by her beauty. his shield and sword lie abandoned on the floor. Echoing the lovers’ bliss, a pair of white doves, symbolizing Peace, nest in Mars’s helmet.
