Bona Sforza, the second wife of Sigismund I of Poland, asked Bartolommeo Berrecci, Francisco the Florentian, Giovanni Maria Padovano, Santi Gucci and others to do this task.
King Sigismund I the Old, who ascended to the throne in 1507, was a sponsor of many artists, and begun a major project - under Florence architect Bartolommeo Berrecci - of remaking the ancient residence of the Polish kings, the Wawel Castle, into a modern Renaissance residence.
