Henry Plantagenet and Aliénor of Aquitaine built in Poitiers the guard's hall of the Counts' Palace, in the center of the town, on its highest eminence.[205] The wall-arcading is like contemporary work in the cathedral and the church of St. Radegund. In late-Gothic times the south wall was remade. In this hall the second husband of Isabella of Angoulême made amends to his suzerain, Alphonse of Poitiers, for the war to which her jealous haughtiness had forced him. In this hall in 1307-08 the accused Templars were interrogated by Clement V, the pontiff who initiated the residence at Avignon, and the consequent papal subserviency to the French crown, Philippe le Bel cowed the pope, and the group of anti-cleric legists who controlled the king arranged that only picked specimens of the doomed military Order should appear at Poitiers. The royal coffers were empty and those of the Templars were full. Torture and intimidation had wrung from all too many of the monk-knights false avowals of guilt. In Spain, where the investigation was carried on without torture, the bishops found no heresy in the Order; instead, they bore testimony to its exemplary standing. One brave old crusader raised his voice in honest speech: "Let him have a care," wrote Joinville, "this king who now reigns. Let him amend his ways, lest God strike him down without mercy." The Grand Master of the Templars, Jacques Molay, was burned publicly in Paris, calling on king and pope to meet him before God's judgment seat within the year. A month later Clement V died, and before 1314 closed, the young king met sudden death. And the people recalled that when Clement was crowned at Lyons, the tiara had been knocked from his head by a collapsing wall and one of its precious jewels lost. Less discouraging were other doings of Clement V in Poitiers. Here he dated the nomination of John of Montecorvino (d. 1328), pioneer of Christian missionaries, to the see of Peking. Armed crusading had run its course; the crusade by preaching, prayer, and penance was to begin. Already in 1245 Innocent IV had sent Dominicans to Persia and Franciscans farther east, St. Louis had sent William de Rubruquis to the Mongols, and those astonishing Venetian merchants; the Polos, had roused the papacy to the spiritual needs of Cathay, the far Cathay of the mediæval tradition, to which Columbus was seeking a shorter route when he accidentally discovered America. For thirty years John of Montecorvino missionized Tartary. He translated the New Testament and the Psalms. To encourage missionary activity, Clement V ordered that Greek, Hebrew, and Arabic be taught publicly at Rome, Bologna, Paris, Oxford, and Salamanca.
