Rosso Fiorentino
Montmorency joined the king in Picardy and at the end of the Netherlands campaign marched to relieve Turin. He led the French troops in 1537 when they attacked Artois in the Netherlands and captured many towns before the ten-year truce. On 10 February 1538 the king made him Constable of France. Around this time he also commissioned a "Pietà" (Louvre) from Francis' court artist Rosso Fiorentino.
