 The Duke of Burgundy replied by a letter in which, while disavowing the general principles that formed the major proposition of the argument of Petit, he maintained that the propositions condemned by the Bishop of Paris were not contained in the discourse.Thereupon the three cardinals, entrusted with the duke's appeal, cited the Bishop of Paris to appear before them, and as he failed to do so, they reversed his decision, declaring at the same time that they did not intend thereby to approve of the propositions condemned by him, but only wished to do justice to the Duke of Burgundy, who had not been heard at the trial.From that moment the trial of Jean Petit became the battleground of the ambassadors of France and of the Duke of Burgundy, and even of the Emperor Sigismund.
