Louis XI did not keep much of a representational court life. He had Queen Charlotte and her household kept secluded at the Château of Amboise, where she spent her days with her sisters and courtiers, supervising the education of her daughters (her son was educated by the king), playing chess and marbles, listening to her lute player, doing needlework and fulfilling her religious duties. On rare occasions she was asked to fulfill ceremonial tasks as queen such as greeting foreign guests, for example in 1470, when the king took the powerful Earl of Warwick and the Duke of Clarence from England to Amboise to visit her. Charlotte was interested in literature and praised for the taste and excellence of her personal library. She left a collection of about one hundred manuscripts, which would become the genesis of the Bibliothèque nationale of France.
