The proofs of the forgery, one would think, were sufficient before the cause came to trial; yet, after a statement of the principal allegations on both sides, the king adjourned the hearing to another day. But that day was not to dawn for Mahaut. On November 23, 1329, the countess was at Poissy, where she dined with the king, going on to the convent of Maubuisson to pass the night, and thence to Paris next day. Here she fell suddenly ill; and her own physician, Thomas le Miesier, was sent for in all haste from Arras. The crude or dangerous remedies of the medicine of the day were powerless to relieve Mahaut; phlebotomy and purgatives probably served but to exhaust her already depleted strength, and the physicians recognized that her end was at hand. Couriers rode in haste from the Hotel d'Artois in Paris to Queen Jeanne, to the Duke of Burgundy, to the Count of Flanders, on the 26th, and as many as three to the king next day, bearing news of the great countess's peril. Jeanne came to her mother with all speed, but the end had come before she could reach Paris; the good Countess of Artois breathed her last on November 27th. She who had expended considerable sums in the pomp of funerals, tombs, and effigies for others was buried very simply, at her own request, in the Abbey of Maubuisson, where her grave was marked at first by a plain, flat copper plate, hardly raised above the level of the pavement. In accordance with a custom not unusual in her day, the body was opened and the heart taken to the Franciscan Church in Paris, where it was interred, as she had directed, _juxta sepulturam Roberti carissimi filii mei_--"beside the grave of my very dear son Robert."
