For countless time French schoolchildren learn that
St. Louis made his judgments under the oak of Vincennes forest (near a mansion where he liked to reside).
The reign of Louis IX of France is a rich mix of diplomatic skills, intellectual activity (creation of the Sorbonne), proselytism (the Crusades), and fight against the major feudals.
In these now assumed dark times that we name the Middle Ages, the principles of Roman law were not forgotten. The specialist was
Pierre de Fontaines, who held the position of grand chamberlain (chambellan) of Louis IX. The king asked him in 1253 to write a book of legal advice, which was intended to adapt the broad principles of law and justice in this new social threat: great feudalism.
A manuscript copy of this book will be on sale in
Paris (Hôtel Drouot) on October 16, by the auction house Lafon.
This copy is written in a variant of the Old French, the Picard dialect. Analysing the book in 1846, Marnier noted that the most correct copy of the text, and probably closer to the original, was in dialect of Ile de France (1). While it is easy to indicate the date of original text, it is more difficult to know the date of the submitted copy. If it is in good condition, the estimate of 60 K € seems far too low.
I can not resist the temptation to mention also a document of the Archives of France, dating back to 1259, by which King Louis IX provides an annual pension of fifty Paris pounds (livres parisis) to the jurisconsult Pierre de Fontaines (2).
