With the discovery of the mariner's compass navigators became more bold and daring, and gradually extended their explorations until they discovered the way to India around the Cape of Good Hope. Near the close of the fifteenth century the belief prevailed that the earth was flat and inhabited only on the upper side. Beyond the shores of lands then known it was thought there hung a pall of fog and darkness. The sea was referred to as the "Sea of Darkness" beyond the boundaries known to man. Far off in or beyond the ocean it was believed great dragons had their lair, and if any man should be so unfortunate as to drift among them he would return no more. Mariners had been afraid to traverse the seas far beyond the sight of land. Shortly before the end of this century there came one navigator more daring than his fellows, who proposed to cross the sea. After many pleadings and attempts to interest some one with means in the venture, he finally succeeded and the remarkable feat was done. In accomplishing this he made discoveries that the Lord, in his wisdom, had kept hid from the nations of the east all down through the ages, until in his own due time he desired them to be revealed. Columbus was moved upon by the Spirit of the Lord and crossed the waters in fulfilment of predictions made by a prophet, who lived on this continent, five hundred years before the birth of Christ. The "Reformation" All these things played an important part in the establishment of individual and religious freedom. The most important agency of all in this great work was doubtless the so-called "Reformation," which was in fact a revolution from the bondage of the church of Rome. Great men of intellectual power began to undermine the thraldom of the religious world. This rebellion against the dominion of Rome was almost simultaneous in the various lands. In England, Scandinavia, France, Switzerland, the Netherlands and Germany, many "reformers" arose near the end of the fifteenth and during the sixteenth century. They were of varying degrees of enthusiasm and opposition to the teachings of that time. In the beginning their only desire was to correct evils within the Catholic Church, but failing in this many of them openly rebelled and set up independent churches of their own. Martin Luther The greatest of these "reformers" was Martin Luther in Germany, who did more than any other individual in casting off the yoke of bondage placed upon the people by the papacy. Powerful princes came to his aid, but there was not in Germany at that time the cohesion of the people, or the centralization of power, that existed in England under Henry VIII, or in Sweden, where Gustavus Vasa reigned. Luther's task, therefore, was a heavy one, but he nobly carried it through to the bitter end. The Protestant Revolution a Preparatory Work
