Written in French on vellum, it certified her annual accounts for the previous year to the sum of “44,828 livres, 13 sols and 9 deniers” and instructed her secretary and comptroller general to sign off the expense.

This is an absolute turning point in her life Thomas Venning

Thomas Venning, Christie’s head of books and manuscripts, said: “On the face of it, this is rather an impersonal document as she is signing off her accounts, but this is an absolute turning point in her life. “The year covered by these accounts had seen the deaths of both her mother, Mary of Guise, Regent of Scotland, whom she had not seen since she was eight, and her husband, Francois II.”
