His second consort Bona Sforza, daughter of Gian Galeazzo Sforza of Milan, was also instrumental in developing the Polish Renaissance and brought renowned Italian artists, architects and sculptors from her native country. It was under Sigismund's reign that Renaissance began to flourish in Poland and in the Grand Duchy of Lithuania. Sigismund II Augustus later continued his father's legacy.
