But though Italy seemed thus to have zealously embraced the enterprise, Martin knew that, in order to ensure success, it was necessary to enlist the greater and more warlike nations in the same engagement; and having previously exhorted Peter to visit the chief cities and sovereigns of Christendom, he summoned another council at Clermont in Auvergne [k]. The fame of this great and pious design being now universally diffused, procured the attendance of the greatest prelates, nobles, and princes; and when the pope and the Hermit renewed their pathetic exhortations, the whole assembly, as if impelled by an immediate inspiration, not moved by their preceding impressions, exclaimed with one voice, IT IS THE WILL OF GOD! IT IS THE WILL OF GOD! Words deemed so memorable, and so much the result of a divine influence, that they were employed as the signal of rendezvous and battle in all the future exploits of those adventurers [l]. Men of all ranks flew to arms with the utmost ardour; and an exterior symbol too, a circumstance of chief moment, was here chosen by the devoted combatants. The sign of the cross, which had been hitherto so much revered among Christians, and which, the more it was an object of reproach among the pagan world, was the more passionately cherished by them, became the badge of union, and was affixed to the right shoulder, by all who enlisted themselves in this sacred warfare [m].
