of the Virgin At the east end of the cathedral is the Chapel of the Virgin, dedicated to the Virgin Mary. It was constructed by master builder Jean Davi beginning in 1302, when the adoration of the Virgin began to play a larger role in Christian theology, and replaced a more modest earlier chapel. Following the style of the 14th century, the windows fill the entire upper portion of the walls, while the lower walls are covered with elaborate tracery and sculpture. Traces of gilding and pigment on the walls show that the chapel was originally brightly colored. The central feature of the chapel is an enormous altar, made in the 17th century, framing a painting of the Virgin surrounded by carved and sculptural decoration. The chapel also contains the tomb of Cardinal Georges d'Amboise, the principal patron of the Gothic cathedral, and his nephew and successor, Cardinal Georges II d'Amboise. It is placed against the south wall. The nephew, Georges II, moved the statue of his uncle to the side of the tomb and placed his own in the central position. The baldaquin or upper portion of the tomb is lavishly decorated with sculpture of the Apostles, in pairs, separated by Sibyls and Biblical kings. The top of the tomb is ornamented with sculpted candelabra and tempietti. or miniature classical temples. The other monumental tomb in the chapel is that of Louis and Pierre de Brézé, made between 1536 and 1541 in a purely Renaissance style. Louis, who died in 1531, was the grandson of Pierre, and was Senechal and Governor of Normandy. His wife was Diane de Poitiers, who was the mistress of King Henri II of France; it was she who commissioned the tomb. Its main elements are a triumphal arch, under which Louis, in armor and on horseback, is passing in triumph. He appears again at the bottom as a corpse, almost nude. Diane is depicted next to his corpse, kneeling. The tomb is attributed to the prominent French Renaissance sculptor Jean Goujon, who was active during this period as a sculptor to Henri II. Stained glass A considerable portion of the original stained glass from the 13th century is still in place. It dates from about the same time as the early windows of Chartres Cathedral and Bourges Cathedral. There are five bays with windows of early glass found in the collateral chapels of the
