The name of Olivier de La Marche is inextricably linked with the exaltation of the knightly idea and the glorification of the Burgundian court. He grew up at the court of the Burgundian dukes and went through the ranks, starting as a stable page and ending as the first chamberlain and captain of the guard. Organizing the daily life of the court for thirty years, Olivier de La Marche thoroughly studied it and reflected it in his works. La Marche is one of the “great rhetoricians”; about fifteen poems and eight treatises are attributed to him. His most famous work, “Memoirs,” was completed by him shortly before his death in 1502. In this book, we present to the domestic reader two treatises by Olivier de La Marche. These are “Description of the Court of Duke Charles of Burgundy, nicknamed the Brave,” written by order of the English king Edward IV, and “Treatise on the wedding of Monsignor Duke of Burgundy and Brabant.” These texts have been selected as one of the most striking evidence of Burgundian ceremonial. The first of the treatises reflects the complex internal structure of the court, while the second gives an example of its brilliant functioning.
