In 1576 Isabella dei Medici, Francesco's sister, was strangled in her nuptial bed by her husband, Paolo Giordano Orsini, whom she had betrayed. Piero dei Medici, Francesco's brother, mur dered his wife Eleonora of Toledo from the same motive. Still louder scandal was caused by the duke's passion for the famous Bianca Cappello, a Venetian of noble birth, who had eloped with and married a young Florentine named Pietro Buonaventuri. Francesco nominated her husband to a post at court. Upon this, Buonaventuri behaved with so much insolence, even to the nobil ity, that one evening he was found murdered in the street. After the death of the grand-duchess in 1578 he married Bianca. The grand-duke died at his villa of Poggio a Caiano on Oct. 18, 1587, and the next day Bianca also expired. Rumour asserted that she had prepared a poisoned tart for the cardinal, and that, when he suspiciously insisted on the grand-duke tasting it first, Bianca desperately swallowed a slice and followed her husband to the tomb.
Such was the life 'of Francesco dei Medici, and all that can be said in his praise is that he gave liberal encouragement to a few artists, including Giovanni Bologna (q.v.). He was the founder of the Uffizi gallery, of the Medici theatre, and the villa of Pratolino ; and during his reign the Della Cruscan academy was instituted.
He re-established the administration of justice, and sedulously attended to the business of the state. Tuscany revived under his rule, and regained the independence and political dignity that his brother had sacrificed to love of ease and personal indulgence. He ensured the prosperity of Leghorn, by an edict enjoining toleration towards Jews and heretics, which led to the settlement of many foreigners in that city. He improved the harbour and established canal communication with Pisa, and carried out many works of public utility in the duchy. He retained the reprehensible custom of trading on his own account, keeping banks in many cities of Europe. In foreign policy he sought emancipation from Spain.
During this grand-duke's reign the Tuscan navy was notably increased, and did itself much honour on the Mediterranean. The war-galleys of the knights of St. Stephen were despatched to the coast of Barbary to attack Bona, the headquarters of the corsairs, and they captured the town with much dash and bravery. In the
following year (16o8) the same galleys achieved their most bril liant victory in the archipelago over the stronger fleet of the Turks, by taking nine of their vessels, seven hundred prisoners, and jewels of the value of 2,000,000 ducats.
Cosimo II.—Ferdinand I. died in 1609, leaving four sons, of whom the eldest, Cosimo II., succeeded to the throne at the age of nineteen. Like his predecessors, Cosimo II. studied to promote the prosperity of Leghorn, and he deserves honour for abandoning all commerce on his own account. He was fond of luxury, spent freely on public festivities and detested trouble. Tuscany was apparently tranquil and prosperous; but the decay of which the seeds were sown under Cosimo I. and Ferdinand I. became before long beyond all hope of remedy. Cosimo II. protected Galileo Galilei. He recalled him to Florence in 161o, and nominated him court mathematician and philosopher. Cosimo died in February 1621. His mother, Cristina of Lorraine, and his wife, Maddalena of Austria, had been nominated regents and guardians to his eldest son Ferdinand IL, a boy of ten.
