In 1471, around the time the copper ball was placed atop the Duomo, Verrochio & Co. was involved, as were most of the other artisans of Florence, in the festivities organized by Lorenzo de’ Medici for the visit of Galeazzo Maria Sforza, the cruel and authoritarian (and soon-to-be assassinated) Duke of Milan….Verrochio’s shop had two major tasks for the festivities: redecorating the Medici’s guest quarters for the visitors and crafting a suit of armor and an ornate helmet as a gift.
The Duke of Milan’s cavalcade was dazzling even to the Florentines who were used to Medicean public spectacles. It included two thousand horses, six hundred soldiers, a thousand hunting hounds, falcons, falconers, trumpeters, pipers, barbers, dog trainers, musicians, and poets. It’s hard not to admire an entourage that travels with its own barbers and poets.
