From 1308 to 1332 the wide, plain west façade of St. Jean's cathedral was done. Two of the Avignon popes were crowned here in those days, Clement V, the builder of Bordeaux's choir, and John XXII. The great dukes of the west, Philippe le Hardi and his son Jean sans Peur, being hereditary canons of the cathedral, often sat in its choir stalls. Of their time is the astronomical clock in the transept. For ten years, prior to 1429, Jean Gerson lived in the old Christian city, teaching little children their catechism, and the only payment he craved was that they should pray: Lord have mercy on your poor servant Gerson. He had been worsted by his century's treachery, bloodshed, foreign rule, and church schism; but after his death Lyons revered him as a saint, and carved his device, _Sursum Corda_, on a chapel in the church of St. Paul. Scholars have decided against Gerson as author of the _Imitation of Christ_, yet during two centuries he was so believed to be, and his memory will be dear to those who have found inspiration in that precious book.
Lyons played so important a part in the revival of late-Gothic art that it was called the French Florence. Its new school of glassmakers decorated the church of Brou, at Bourg-en-Bresse, not far away.[162] Two elaborate Flamboyant Gothic tombs were put up in the cathedral--that of Archbishop de Saluces (d. 1419) by Jacques Morel, and that of Cardinal Charles de Bourbon, a grandson of John the Fearless of Burgundy, and son of the Bourbon duke commemorated by the Souvigny tomb. From 1486 to 1501, he and his brother Pierre de Bourbon, son-in-law of Louis XI, added to Lyons Cathedral the splendid chapel of their name whose walls are carved with their winged stag and the device Espérance. Unfortunately the windows, made by the Lyons master Pierre de la Paix, exist no longer, save a few upper panels, in one of which is an angel of rare beauty holding the Bourbon arms. Frequently in France one meets the donations of Henry IV's art-loving forbears, at Chartres, Tours, Souvigny,[163] Champigny-sur-Veude. Henry was married in Lyons Cathedral, in 1600, to Marie de Medici, daughter of another line of connoisseurs.
Like many a cathedral of France, Lyons was at its richest when it was sacked most piteously both in 1560 and 1562. Every church in the city was devastated by the cruel Baron des Adrets, who led the Huguenots one year, the Catholics the next, for in those bitter civil wars religion was often the thinnest cloak. The Huguenots destroyed the tomb of Cardinal de Saluces, with its eighteen alabaster statuettes, smashed the Bourbon chapel and tomb, broke up the Flamboyant rood screen, and dragged through the streets a silver statue of Christ that had surmounted it. On the west façade some fifty large statues were brought down, though happily the lovely little scenes chiseled under their brackets were spared. It is told how an archer shattered Our Lady's image, but when he attempted to dislodge that of God the Father, on the pignon, it fell and killed him. Lyons was again the scene of saturnalian havoc during the Revolution, when by the thousand her citizens were mowed down with grape shot because they chose to adhere to the old régime. A passageway was broken open in the walls of the cathedral to permit the entry of a chariot bearing the Goddess of Reason.
