After an ineffectual effort in her favor made by the Connétable, probably in the year 1556, Catherine paid great court to the Guises, and schemed to detach them from Diane's party so as to set them in opposition to Montmorency. But, unfortunately, Diane and the Connétable were as virulent against the Protestants as the Guises were. Hence their antagonism lacked the virus which religious feeling would have given it. Besides, Diane boldly defied the Queen's plans by coquetting with the Guises and giving her daughter to the Duc d'Aumale. She went so far that she has been accused by some writers of granting more than smiles to the gallant Cardinal de Lorraine.[E] The signs of grief and the ostentatious regret displayed by Catherine on the King's death cannot be regarded as genuine. The fact that Henri II. had been so passionately and faithfully attached to Diane de Poitiers made it incumbent on Catherine that she should play the part of a neglected wife who idolized her husband; but, like every clever woman, she carried on her dissimulation, and never ceased to speak with tender regret of Henri II. Diane herself, it is well known, wore mourning all her life for her husband, Monsieur de Brézé. Her colors were black and white, and the King was wearing them at the tournament when he was fatally wounded. Catherine, in imitation no doubt of her rival, wore mourning for the King to the end of her life. On the King's death, the Duchesse de Valentinois was shamelessly deserted and dishonored by the Connétable de Montmorency, a man in every respect beneath his reputation. Diane sent to offer her estate and Château of Chenonceaux to the Queen. Catherine then replied in the presence of witnesses, "I can never forget that she was all the joy of my dear Henri; I should be ashamed to accept, I will give her an estate in exchange. I would propose that of Chaumont-on-the-Loire." The deed of exchange was, in fact, signed at Blois in 1559. Diane, whose sons-in-law were the Duc d'Aumale and the Duc de Bouillon, kept her whole fortune and died peacefully in 1566 at the age of sixty-six. She was thus nineteen years older than Henri II. These dates, copied from the epitaph on her tomb by an historian who studied the question at the end of the last century, clear up many historical difficulties; for many writers have said she was forty when her father was sentenced in 1523, while others have said she was but sixteen. She was, in fact, four-and-twenty. After reading everything both for and against her conduct with Francis I., at a time when the House of Poitiers was in the greatest danger, we can neither confirm nor deny anything. It is a passage of history that still remains obscure. We can see by what happens in our own day how history is falsified, as it were, in the making.
