While there is a (relative) abundance of secondary sources on Burgundy, I am stumped and puzzled as to where to search for primary sources. If anyone here could direct me towards a place to find primary sources, that would be wonderful. Thank you!
Start with the footnotes and bibliography of your secondary sources! Eleanor de Poitiers, Olivier de la Marche, Mathieu d'Eschouchy are just a few of the substantial-length-work authors I can think of off the top of my head, and I learned about all of them from reading secondary sources on court life.
