These Letters first appeared in French, in 1628, just thirteen years after the death of their witty and beautiful authoress, who, whether as the wife for many years of the great Henri of France, or on account of her own charms and accomplishments, has always been the subject of romantic interest. The letters contain many particulars of her life, together with many anecdotes hitherto unknown or forgotten, told with a saucy vivacity which is charming, and an air vividly recalling the sprightly, arch demeanour, and black, sparkling eyes of the fair Queen of Navarre. She died in 1615, aged sixty-three. These letters contain the secret history of the Court of France during the seventeen eventful years 1565-82. The events of the seventeen years referred to are of surpassing interest, including, as they do, the Massacre of St. Bartholomew, the formation of the League, the Peace of Sens, and an account of the religious struggles which agitated that period. They, besides, afford an instructive insight into royal life at the close of the sixteenth century, the modes of traveling then in vogue, the manners and customs of the time, and a picturesque account of the city of LiPge and its sovereign bishop.
