Mars and Venus, Allegory of Peace (Mars et V?nus, all?gorie sur la Paix), 1770. Additional Info: In this gentle allegory of peace by Louis Jean Fran?ois Lagren?e, 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. Her love has tempered his fierce character, and his shield and sword lie abandoned on the floor. Echoing the lovers bliss, a pair of white doves, symbolizing Peace, build a nest in Marss helmet.
