Passing over the attempts of the very early travellers to become acquainted with the geographical portion of Africa, in which much fiction, and little truth, were blended, we arrive at that period, when the spirit of discovery began to manifest itself amongst some of the European states. The darkness and lethargy, which characterised the middle ages, had cast their baneful influence over every project, which had discovery for its aim, and even the invaluable discovery of the mariner's compass, which took place at the commencement of the thirteenth century, and which opened to man the dominion of the sea, and put him in full possession of the earth had little immediate effect in emboldening navigators to venture into unfrequented seas. At a somewhat earlier period, it is true, the Hanse Towns and the Italian republics began to cultivate manufactures and commerce, and to lay the foundation of a still higher prosperity, but they carried on chiefly an inland or coasting trade. The naval efforts, even of Venice or Genoa, had no further aim than to bring from Alexandria, and the shores of the Black Sea, the commodities of India, which had been conveyed thither chiefly by caravans over land. Satisfied with the wealth and power, to which they had been raised by this local and limited commerce, these celebrated republics made an attempt to open a more extended path over the ocean. Their pilots, indeed, guided most of the vessels engaged in the early voyages of discovery, but they were employed, and the means furnished, by the great monarchs, whose ports were situated upon the shores of the Atlantic. The first appearance of a bolder spirit, in which the human mind began to make a grand movement in every direction, in religion, science, freedom, and liberty, may be dated from about the end of the fifteenth century. The glory of leading the way in this new career, was reserved for Portugal, then one of the smallest, and least powerful of the European kingdoms.
