Schifanoia Palace, east wall, month of April: “Triumph of Venus”. Detail.Fresco by Francesco del Cossa (1468-1470).Venus' chariot is pulled by elegant swans. Mars is kneeling and chained in front of her: an obvious allusion to the power that love can have over war. To underline the idyllic climate favored by the goddess' protection, some young courtiers exchange effusions, play and play music.
