The monk spoke for more than five hours, reviewing sacred history, and the histories of Greece, Rome, and Persia, and the precedents of Phineas, Absalom the son of David, Queen Athaliah, and Julian the Apostate, to prove "that it is lawful, and not only lawful, but honorable and meritorious, in any subject to slay or cause to be slain a traitor and disloyal tyrant, especially when he is a man of such mighty power that justice cannot well be done by the sovereign." This principle once laid down, John Petit proceeded to apply it to the Duke of Burgundy, "causing to be slain that criminal tyrant, the Duke of Orleans, who was meditating the damnable design of thrusting aside the king and his children from their crown;" and he drew from it the conclusion that "the Duke of Burgundy ought not to be at all blamed or censured for what had happened in the person of the Duke of Orleans, and that the king not only ought not to be displeased with him, but ought to hold the said lord of Burgundy, as well as his deed, agreeable to him, and authorized by necessity." The defence thus concluded, letters were actually put before the king, running thus: "It is our will and pleasure that our cousin of Burgundy, his heirs and successors, be and abide at peace with us and our successors, in respect of the aforesaid deed, and all that hath followed thereon; and that by us, our said successors, our people and officers, no hinderance, on account of that, may be offered them, either now or in time to come." Charles VI., weak in mind and will, even independently of his attacks, signed these letters, and gave Duke John quite a kind reception, telling him, however, that "he could cancel the penalty, but not the resentment of everybody, and that it was for him to defend himself against perils which were probably imminent." The duke answered proudly that "so long as he stood in the king's good graces, he did not fear any man living." Three days after this strange audience and this declaration, Queen Isabel, but lately on terms of the closest intimacy with the Duke of Orleans, who had been murdered on his way home after dining with her, was filled with alarm, and set off suddenly for Melun, taking with her her son Louis, the _dauphin_, and accompanied by nearly all the princes, who, however, returned before long to Paris, being troubled by the displeasure the Duke of Burgundy testified at their departure.

For more than four months, Duke John the Fearless remained absolute master of Paris, disposing of all posts, giving them to his own creatures, and putting himself on good terms with the university and the principal burgesses.
A serious revolt amongst the Liigese called for his presence in Flanders.
The first troops he had sent against them had been repulsed; and he felt the necessity of going thither in person.

But two months after his departure from Paris, on the 26th of August, 1408, Queen Isabel returned thither from Melun, with the _dauphin_ Louis, who for the first time rode on horseback, and with three thousand men-at-arms.

She set up her establishment at the Louvre.

The Parisians shouted "Noel," as she passed along; and the Duke of Berry, the Duke of Bourbon, the Duke of Brittany, the constable, and all the great officers of the crown rallied round her.
Two days afterwards, on the 28th of August, the Duchess of Orleans arrived there from Blois, in a black litter drawn by four horses caparisoned in black, and followed by a large number of mourning carriages.
