Here is the old hero in his dungeon in Florence. While he dozed, the night before he was to be burned, the jailer saw a rare, sweet smile upon his face. "What is it?" the guard asked. "I hear the sounds of falling chains, and their clangor is like sweet music in my ears." Then, with smiling face he went to his martyrdom. And here is Michael Angelo. Grown old and blind, he gropes his way into the gallery of the Vatican, where with uplifted face his fingers feel their way over the torso of Phidias. Lingering by him one day the Cardinal Farnese heard the old sculptor say: "Great is this marble; greater still the hand that carved it; greatest of all, the God who fashioned the sculptor. I still learn! I still learn!" And he too went forward sustained by his vision of perfect beauty. And here is John Huss, looking between the iron bars of his prison upon an army of pikes and spears, massed before his jail; but the martyr endured his danger by the foresight of the day when the swords then wielded for repression of liberty of thought would flash for its emancipation. And here is Walter Scott ruined by the failure of his publishers, just at the hour when nature whispered that he had fulfilled his task and earned his respite. But he girded himself anew for the battle, and sustained his grievous loss through the foresight of the hour when the last debt would be paid and his again would be a spotless name. And here is that youth, Emerson, looking out upon a world full of noise and strife, full of the cries of slaves and the warfare of zealots. He was sustained by the foresight of a day when God would breathe peace o'er all the scene. With hope shining in his face, he began to "take down men's idols with such reverence that it seemed an act of worship." And what shall we more say? By the sight of the invisible, Dante endured his scaffold; the heroes, hunted like partridges upon the mountains, endured their caves and the winter's cold; martyrs endured the scourge and fagot. In every age, the great, by the sight of the invisible, have been lifted into the realms of tranquillity. Outwardly, there may have been the roar and boom of guns, but inwardly men were lutes with singing harps. As the householder sitting by his blazing hearth thinks not of the sleet and hail falling on the roof of slate, so the soul abides in peace over which has been reared the castle and covert of God's presence.
