Francesco I Sforza
Francesco's successor Ludovico commissioned Leonardo da Vinci to design an equestrian statue as part of a monument to Francesco I Sforza. A clay model of a horse which was to be used as part of the design was completed by Leonardo in 1492 — but the statue was never built. In 1999 the horse alone was cast from Leonardo's original designs in bronze and placed in Milan outside the racetrack of Ippodromo del Galoppo.
