"Le chevalier délibéré" by Olivier de La Marche is a French allegorical poem written in 1483. A knight named Acteur, in the autumn of his life, embarks on a quest to confront Death's invincible warriors before retreating to a monastery. Along his journey, he encounters allegorical figures and witnesses fateful duels involving the Burgundian rulers Philip the Good, Charles the Bold, and Mary of Burgundy. This melancholic work became a key text of Burgundian culture and the favorite book of Emperor Charles V.
