Pêro da Covilhã

In the process of expanding the trade routes, Portuguese navigators mapped unknown parts of Africa, and began exploring the Indian Ocean. In 1487, an overland expedition by Pêro da Covilhã made its way to India, exploring trade opportunities with the Indians and Arabs, and winding up finally in Ethiopia. His detailed report was eagerly read in Lisbon, which became the best informed center for global geography and trade routes.
