Pierre de Bosredont, commander in the Champagne of the Order of the Hospital of St. John of Jerusalem and son of a royal counselor and chamberlain, commissioned this highly personal Book of Hours. His arms (which also appear full-page), name, and motto appear in many of the borders. A most unusual miniature depicts a battle between the Turks and the Knights of Rhodes under the command of Pierre's relative, George de Bosredont. Finally, Pierre himself is depicted three times, always wearing the Maltese cross of the Knights Hospitalers.
