Niccolò de' Carissimi, one of Galeazzo Maria's counsellors, furnished further details of the rooms and garden:
decorated on every side with gold and fine marbles, with carvings and sculptures in relief, with pictures and inlays done in perspective by the most accomplished and perfect of masters even in the very benches and floors of the house; tapestries and household ornaments of gold and silk;silverware and bookcases that are endless... then a garden done in the finest of polished marbles, with diverse plants, which seems a thing not natural but painted.
