This allegorical scene depicts the triumph of Peace over War, of Love over Hate, a subject particularly resonant at the height of the Thirty Years' War (1618-48). Venus, Goddess of Love, nourishes her son Cupid, while Mars, God of War, is literally disarmed by love: a cherub mischievously undoes one of his armour straps. Cupid is balanced on Mars's shield, which is decorated with the monstrous face of Medusa; his precarious position refers to the unstable nature of love and peace.
Venus repeats the figure of Peace in Rubens’s Peace and War in the National Gallery, London, while the figures of Mars and Cupid in this painting seem to derive from Dürer’s print of the Penance of Saint John Chrysostom.
