Manuscript comprises two separate parts: (A) f.1-110 Giles of Rome, De regimine principum and (B) f.111-207 Roger of Waltham, Compendium morale. They were probably still separate in 14/15th century (only the first features in the note of content of that date on f.1r and is reported in the early 15th century “in recompensationem” booklist), but they had been brought together by s. 15/16th century at the latest (both are registered in the list of content that was added to f.iiᵛ by Thomas Swalwell).
