Taking with him the lessons he learned from the Colleoni monument creation under Verrocchio to Milan, Da Vinci dared to dream bigger and create a more impressive equestrian statue. Even before he moved to Milan, there were discussions about his creation of this impressive monument. In 1482, Da Vinci accepted the challenge to build the greatest equestrian statue as a monument to Francesco Sforza, the father of Lodocivo Sforza, the Duke of Milan (Grierson, 1959).
