It often happens that popular emotions, however profound and general, remain barren, just as in the vegetable world many sprouts appear at the surface of the soil and die without having grown and fructified.  It is not sufficient for the bringing about of great events and practical results that popular aspirations should be merely manifested; it is necessary, further, that some great soul, some powerful will, should make itself the organ and agent of the public sentiment, and bring it to fecundity by becoming its personification.  The Christian passion, in the eleventh century, for the deliverance of Jerusalem and the triumph of the Cross was fortunate in this respect.  An obscure pilgrim, at first a soldier, then a married man and father of several children, then a monk and a vowed recluse, Peter the Hermit, who was born in the neighborhood of Amiens, about 1030, had gone, as so many others had, to Jerusalem “to say his prayers there.”  Struck disconsolate at the sight of the sufferings and insults undergone by the Christians, he had an interview with Simeon, patriarch of Jerusalem, who “recognizing in him a man of discretion and full of experience in affairs of the world, set before him in detail all the evils with which the people of God, in the holy city, were afflicted.  ‘Holy father,’ said Peter to him, ’if the Roman Church and the princes of the West were informed, by a man of energy and worthy of belief, of all your calamities, of a surety they would essay to apply some remedy thereto by word and deed.  Write, then, to our lord the pope and to the Roman Church, and to the kings and princes of the West, and strengthen your written testimony by the authority of your seal.  As for me, I shrink not from taking upon me a task for the salvation of my soul; and with the help of the Lord I am ready to go and seek out all of them, solicit them, show unto them the immensity of your troubles, and pray them all to hasten on the day of your relief.’” The patriarch eagerly accepted the pilgrim’s offer; and Peter set out, going first of all to Rome, where he handed to Pope Urban II. the patriarch’s letters, and commenced in that quarter his mission of zeal.  The pope promised him not only support, but active co-operation when the propitious moment for it should arrive.  Peter set to work, being still the pilgrim everywhere, in Europe, as well as at Jerusalem.  “He was a man of very small stature, and his outside made but a very poor appearance; yet superior powers swayed this miserable body; he had a quick intellect and a penetrating eye, and he spoke with ease and fluency. . . .  We saw him at that time,” says his contemporary Guibert de Nogent, “scouring city and town, and preaching everywhere; the people crowded round him, heaped presents upon him, and celebrated his sanctity by such great praises that I remember not that like honor was ever rendered to any other person.  He displayed great generosity in the disposal of all things that were given him.
