 The most recent monumental equestrian sculpture in Florence, before that of Duke Cosimo I, had been da Vinci’s never-completed monument to Giangiacomo Trivulzio.The Torrie horse bears a close relationship to several drawings by da Vinci related to this project in the collection of Her Majesty the Queen at Windsor.Other artists, too, knew and learned from da Vinci’s study of the horse, but none came so close as Giovanni da Bologna to his vision of the beauty of the animal celebrated by art and science together.
