The remains of the Benedictine monastery to which the care of these shrines was entrusted are south of the cathedral, forming three sides of a square, of which the cathedral nave was the fourth. Beyond is an open green, with the castle on the farther side and old buildings on either hand. From this green the castle is entered by a gateway with massive doors, but, while the structure is picturesque, it is not very ancient, excepting this gateway. It has mostly been rebuilt since the twelfth century. This was the palace of the bishops of Durham, of whom Antony Bek raised the power of the see to its highest point. He was prelate, soldier, and politician, equally at home in peace or war, at the head of his troops, celebrating a mass, or surrounded by his great officers of state. He was the first who intruded upon the solitude of St. Cuthbert by being buried in the cathedral. Here lived also Richard of Bury, noted as the most learned man of his generation north of the Alps, and the first English bibliomaniac. Bishop Hatfield also ruled at Durham, famous both as architect and warrior. Cardinal Wolsey lived here when Archbishop of York and his quarrel with Henry VIII. resulted in the Durham palatinate beginning to lose part of its power, so that in the days of his successor, Tunstall, it came to be the "peace of the king," and not of the bishop, that was broken within its borders. Here also ruled the baron-bishop Crewe, who was both a temporal and a spiritual peer, and Bishop Butler, the profound thinker. But the bishops live there no longer, their palace being moved to Auckland, while the university is located in the castle. It is the Northern University, first projected in Cromwell's time. About a mile to the westward of Durham was fought the battle of Neville's Cross in October, 1346. This was a few months after Edward had won the battle of Crecy in France, and the King of Scotland, taking advantage of the absence of the English king and his army, swept over the Border with forty thousand men, devastating the entire country. His chief nobles accompanied him, and to encourage the troops the most sacred relic of Scotland, the "Black Rood," a crucifix of blackened silver, was present on the battlefield. This had been mysteriously delivered to David I. on the spot in Edinburgh where to commemorate it Holyrood Abbey was afterwards founded. But, though King Edward was in France, Queen Philippa was equal to the emergency. An army was quickly gathered under Earl Neville, and Durham sent its contingent headed by the warlike bishop. The invaders drew near the walls of Durham, and the English army, inferior in numbers, awaited them. To confront the "Black Rood," the bishop brought into camp an "ark of God" in obedience to a vision: this was one of the cathedral's choicest treasures, "the holy corporax cloth wherewith St. Cuthbert covered the chalice when he used to say mass." This, attached to the
