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.
