In July 1564, Bianca Buonaventuri became the mother of a little girl, to whom the name Pellegrina--her own dear mother's name--was given. The days of convalescence quickly passed, and Francesco paid his _innamorata_ increasing court. Upon Pietro and Bianca he bestowed a charming palace, on the Lung 'Arno, and provided them with ample means to maintain themselves and it. He appointed Pietro Keeper of his Wardrobe and Clerk of his Privy Closet, on condition that his fascinating girl-wife should be regarded pretty much as "_La cosa di Francesco_." The more the Prince saw of Bianca the stronger grew his passion. She was perfectly irresistible. After the fashion of the day, he poured forth his devotion in graceful madrigals--the first of which, began as follows:-- "A rich and shining Gem hath Dame Nature Taken out of Heaven's treasury, and Wrapping it in a lustrous human veil Hath bestowed it on me, saying, 'To thee I give this beauteous Flora for thine own.'" Meanwhile preparations were going forward for the reception and marriage of the Austrian Archduchess, who reached Florence on 16th November 1565. Reports of her husband's infatuation for Bianca Buonaventuri had of course travelled to Vienna, and Giovanna had not long to wait for their verification. She could not brook the fouling of the marriage-bed nor permit the _liaison_ to go on undenounced. Francesco met her ill-humour with a frown. He pointed to the morals of her father's court, and to the Florentine cult of Platonism, and he bade her mind her own business and not make troubles. Her appeals to Duke Cosimo and to her brother the Emperor Maximilian were in vain. Francesco plainly hinted that she might go back to Vienna if she liked, for nothing that she could say or do would alter his admiration and his devotion for Bianca Buonaventuri. The strictness of married life had long ago disappeared from the conventions of Florentine society. Mutual relationships proved that men might live as they pleased, so long as they did not renounce the offspring, even when they were assured that it was not their own. The term "_Partiti_"--"Sharers" or "Partners"-- perhaps less literally but more emphatically, "kindred souls," was bestowed upon this relationship. Still at no time was Francesco a sensuous man or a libertine like his father. His devotionally-affected mother, Eleanora de Toledo, had trained him in moral ways, and had called forth in him regard for religion and sympathy for charitable objects. Possessed of great self-command and reticence, he never betrayed himself in any way; passionate he was beyond the ordinary, but never revengeful. He loved one woman, and only one, and to her he proved himself faithful until death took them away together; but she was not Giovanna, his political wife, she was Bianca, the wife of his heart and mind.
