Stephen Smith explores Renaissance Florence under the reign of Grand Duke Cosimo Medici. Cosimo’s fledgling court prized the finer things in life and some of the greatest painters, sculptors and craftsmen in world history came to serve the Grand Duke. But successful courtiers had to have brains as well as brawn. The canniest of them looked to theorists like Niccolo Machiavelli for underhand ways to get ahead, whilst enlightened polymaths turned their minds to the heavens, and to ice cream.
