In the year 1428, Don Pedro, the king's _eldest_[5] son, who was a great traveller, went into England, France, and Germany, and thence into the Holy Land and other places, and came home by Italy, through Rome and Venice. He is said to have brought a map of the world home with him, in which all parts of the earth were described, by which the enterprizes of Don Henry for discovery were much assisted. In this map the Straits of Magellan are called the _Dragons-tail_, and the Cape of Good Hope the _Front of Africa_, and so of the rest[6]. I was informed by Francis de Sosa Tavares, that in the year 1528, Don Fernando, the king's eldest son, shewed him a map which had been made 120 years before, and was found in the study of Alcobaza, which exhibited all the navigation of the East Indies, with the cape of Bona Sperança, as in our latter maps; by which it appears that there was as much discovered, or more, in ancient times as now[7]. Though attended with much trouble and expence, Don Henry was unwearied in prosecuting his plan of discoveries. At length Gilianes, one of his servants, passed Cape Bojador, a place terrible to all former navigators, and brought word that it was by no means so dangerous as had been represented, he having landed on its farther side, where he set up a wooden cross in memorial of his discovery. In the year 1433 died John king of Portugal, and was succeeded by his eldest son Duarte or Edward. In 1434, Don Henry sent Alphonso Gonzales Balduja and Gillianes, who penetrated from Cape Bajador to another cape, where they found the country to be inhabited, and went forward to another point of land, whence they returned to Portugal. In 1438 king Duarte died, and his son Alphonso being young, the kingdom was governed during his minority by his uncle Don Pedro. In 1441, Don Henry sent out two ships under Tristan and Antonio Gonzales, who took a prize on the coast, and sailed to Cape Blanco, or the White Cape in lat. 20° N.[8]. From thence they brought home some Moors, from whom Don Henry learned the state of the country. Don Henry sent an account of these discoveries to Pope Martin, by one Fernan Lopez de Savado; and the Pope granted indulgences and everlasting pardon of sins to all who should die in attempting the discovery of the land of the infidels. In the year 1443, Don Henry commanded Antonio Gonzales to carry back the Moors to their own country, where they were ransomed for black Moors with curled hair, or negroes, and some gold; owing to which that place is now called Rio de Oro, or the Golden River, that thereby the desire of discovery might be the more increased. He sent soon afterward one named Nunnez Tristan, who discovered the islands of Arguin, who brought more slaves from thence to Portugal in 1444. One Lancarote, a groom of Don Henrys chamber, and three others, armed certain ships, with which they sailed along the coast to the islands of Garze, where they took 200 slaves, which were the first
