the Duke of Burgundy, was particularly surprised about the developing news of the marriage. Ferdinand knew that the wedding plans were fluctuating and subject to political uncertainties and questions, and this was even more true elsewhere like in the Court of Burgundy. He confided in his son with two major tasks: the first was to give to Charles the Bold the collar of the Order of the Ermine he had created, and welcome him to the Order of the Knights of the Fleece or, the second was to replace, in the entourage of Charles, Nicola di Monforte Pietravalle, Count of Campobasso, a former vassal of Ferdinand who served René of Anjou and had ties to John of Calabria, who recruited mercenaries in Piedmont, Lombardy and Emilia to serve in the army of Burgundy. While Frederick of Aragon arrived at the court of Burgundy, Antoine de Bourgogne, the half- brother of Charles the Bold, set off to Naples with his son Philippe, François d'Este, an illegitimate son of Lionel Este and Guillaume de Rochefort and a hundred men to submit to King Ferdinand the collar of the Order of the Golden Fleece in which he was admitted to the Chapter of Valenciennes in 1473 at the request of Charles the Bold. Arriving at Mechelen around 15 February, Antoine de Bourgogne stayed at Moncalieri from March 4 to March 6 at the Duchess Yolande's estate. He likely met with Frederick at this time at the estate of Chambéry.
