The last of the seven Planets is Saturn, depicted as an old man heavy with melancholy, who is devouring his own children, with a great serpent that is seizing its own tail with its teeth; which Saturn has above him the Sign of Capricorn. In the oval is Decrepitude, and here is depicted Jove in Heaven receiving a naked and decrepit old man, kneeling, who is watched over by Felicity and Immortality, who are casting his garments into the world. This oval is supported by Beatitude, who is upheld by a figure of Justice in the ornament below, who is seated and has in her hand the sceptre and upon her shoulders the stork, with arms and laws around her; and on the parapet below is Geometry.
In the lowest part at the foot, which is about the windows with knee-shaped brackets and the door, is Leah in a niche, representing the Active Life, and on the other side of the same place is Industry, who has a Cornucopia and two goads in her hands. Near the door is a scene in which many masters in wood and stone, architects, and stone-cutters have before them the gate of Cosmopolis, a city built by the Lord Duke Cosimo in the island of Elba, with a representation of Porto-Ferrajo. Between this scene and the frieze in which are the Liberal Arts, is Lake Trasimene, round which are Nymphs who are issuing from the water with tench, pike, eels, and roach, and beside the lake is Perugia, a nude figure holding with her hands a dog, which she is showing to a figure of Florence corresponding to her, who stands on the other side, with a figure of Arno beside her who is embracing and fondling her. And below this is the Contemplative Life in another scene, in which many philosophers and astrologers are measuring the heavens, appearing to be casting the horoscope of the Duke; and beside this, in the niche corresponding to that of Leah, is her sister Rachel, the daughter of Laban, representing the Contemplative Life. The last scene, which is likewise between two niches and forms the conclusion of the whole invention, is Death, who, mounted on a lean horse and holding the scythe, and accompanied by War, Pestilence, and Famine, is riding over persons of every kind. In one niche is the God Pluto, and beneath him Cerberus, the Hound of Hell; and in the other is a large figure rising again from a sepulchre on the last day. After all these things Cristofano executed on the pediments of the windows with knee-shaped brackets some nude figures that are holding the devices of his Excellency, and over the door a Ducal coat of arms, the six balls of which are upheld by some naked little boys, who twine in and out between each other as they fly through the air. And last of all, in the bases at the foot, beneath all the scenes, the same Cristofano painted the device of M. Sforza; that is, some obelisks, or rather triangular pyramids, which rest upon three balls, with a motto around that reads--Immobilis.
