“ The tale that the countess, disguised as a page, witnessed the encounter, appears to have no foundation; but Buckingham, by installing the “widow of his own creation” in his own and his wife’s house, outraged even the lax opinion of that day. He was thought to have originated the project of obtaining the divorce of the childless queen. He intrigued against James, against Sir William Coventry—one of the ablest statesmen of the time, whose fall he procured by provoking him to send him a challenge—and against the great duke of Ormonde, who was dismissed in 1669. ”
