Mouton composed a motet, "Christus vincit", for the election of Leo X as pope in 1513. Leo evidently liked Mouton's music, for he rewarded him with the honorary title, "apostolic notary" on the occasion of a motet he composed for the pope in 1515; the pope made this award during a meeting in Bologna between the French king and the pope after the Battle of Marignano. This trip to Italy was the first, and probably only trip that Mouton made outside France.
