Perugia, Minuccio and Francesco di Rinaldo, and that the upper part was designed by the painter, Lippo Memmi, in 1341.[73] The Chapel at the foot of the tower was begun in 1348, "for a certain miracle that Our Lady the Virgin Mary did"--or at least vowed in that year, as a memorial of deliverance from the Black Death, and built in the third quarter of the fourteenth century. The upper part, with its beautiful frieze of griffins, is the work of Antonio Federighi, and dates from 1460. The statues of saints in their niches merely show to what depths Sienese sculpture had sunk by the latter part of the fourteenth century, before the rise of Giacomo della Quercia. The ruined and restored fresco is Bazzi's last work in Siena. He promised in 1537 that he would have it done by the Feast of Our Lady in August for 60 golden scudi, but went off for a holiday to Piombino after beginning it, and did not return to complete the work till the following year. The door behind the chapel leads into a picturesque and deserted court, with a faded fifteenth century fresco and a number of old armorial bearings on the walls. The Lupa of gilded bronze on the column to the right of the Palace marks the entrance to the apartments of the Signoria. Over the door, two very lean wolves are adoring the crowned Lion of the People. We ascend the steps to the first floor, into a magnificent series of rooms, glowing with masterpieces of Sienese painting. The first room--variously called the _Sala delle Balestre_, the _Sala del Mappamondo_, and the _Sala del Gran Consiglio_--is now a law-court. Here at one epoch the Consiglio della Campana, or Senate, at others the minor councils of the State met. The whole wall above the place of the president of the court is occupied by a vast fresco by Simone Martini painted in 1315, "right marvellously coloured," as Ghiberti calls it. Our Lady, enthroned as Queen of Siena, is holding up the Divine Child standing on her knees to bless the deliberations of the Council; Apostles and the Baptist hold the poles of the canopy, Virgin Martyrs and Angels stand in attendance, while two kneeling Angels offer flowers on behalf of Siena's four sainted patrons--Ansanus, Savinus, Crescentius and Victor. All the faces have the winning sweetness and spiritual loveliness that we find throughout the works of the Sienese school. At the foot of the throne is a poetical inscription: "The angelical flowers, roses and lilies, wherewith the celestial meadow is adorned, do not delight me more than good counsels. But sometimes I see one who, to exalt himself, despises me and deceives my city; and when he speaks worse, he is more praised by each one whom these words condemn." And along the base of the picture is their Queen's answer to the prayers of the Saints: "My beloved ones, be assured that I will make your devout chaste prayers content, as you shall wish. But if the potent oppress the weak, harassing them with shames and harms, your
