Anne of Austria, forgetting that the all-dominant passion of love had led her to regret that she was the wife of the king, that she might marry the Duke of Buckingham, did not deem it possible that her son could stoop so low as to marry any one who was not of royal blood. She therefore regarded without much uneasiness his desperate flirtations, while she was scanning the courts of Europe in search of an alliance which would add to the power and the renown of her son. One of the nieces of Cardinal Mazarin, an Italian girl by the name of Olympia Mancini, was among the first to whom the boy-king of fifteen became specially attached. Olympia was very beautiful, and her personal fascinations were rivaled by her mental brilliance, wit, and tact. She was by nature and education a thorough coquette, amiable and endearing to an unusual degree. She had a sister a little older than herself, who was also extremely beautiful, who had recently become the Duchess of Mercoeur. Etiquette required that in the balls which the king attended every evening he should recognize the rank of the duchess by leading her out first in the dance. After this, he devoted himself exclusively, for the remainder of the evening, to Olympia. It will be remembered that Henrietta, the widowed queen of Charles II., who was daughter of Henry IV. and sister of Louis XIII., was then residing in France. She had no pecuniary means of her own, and, chagrined and humiliated, was a pensioner upon the bounty of the impoverished French court. Henrietta had with her a very pretty daughter, eleven years of age. Being the granddaughter of Henry IV. and daughter of Charles II., she was entitled, through the purity of her royal blood, to the highest consideration in the etiquette of the court. But the mother and the daughter, from their poverty and their misfortunes, were precluded from any general participation in the festivities of the palace.
