The clergy themselves set the example. Many of the bishops, who bore the titles of counts and barons, and who were accustomed to make war in defence of the rights of their bishoprics, thought it their duty to arm for the cause of Jesus Christ. The priests, to give greater weight to their exhortations, themselves assumed the cross; a great number of pastors resolved to follow their flocks to Jerusalem; not a few of them, as we shall see hereafter, having in their minds the rich bishoprics of Asia, and allowing themselves to be led by the hope of some day occupying the most celebrated sees of the Eastern church. In the midst of the anarchy and troubles which had desolated Europe since the reign of Charlemagne, there had arisen an association of noble knights, who wandered over the world in search of adventures; they had taken an oath to protect innocence, to fight against infidels, and, by a singular contrast, called themselves _the Champions of God and of Beauty_. The religion which had consecrated their institution and blessed their sword, called them to its defence, and the order of chivalry, which owes a great part of its splendour and progress to the holy wars, saw its warriors hasten to range themselves under the banners of the cross. Ambition was, perhaps, not foreign to the devotion for the cause of Christ. If religion promised its rewards to those who were going to fight for it, fortune promised them, likewise, riches and the thrones of the earth. All who returned from the East, spoke with enthusiasm of the wonders they had seen, and of the rich provinces they had traversed. It was known that two or three hundred Norman pilgrims had conquered Apulia and Sicily from the Saracens. The lands occupied by the infidels appeared to be heritages promised to knights whose whole wealth consisted in their birth, their valour, and their sword.[44]
