We may well imagine that these stirring words of the Prince must have confirmed Gil Eannes in his resolve to efface the stain of his former misadventure. And he succeeded in doing so; for he passed the dreaded Cape Bojador--a great event in the history of African discovery, and one that in that day was considered equal to a labor of Hercules. Gil Eannes returned to a grateful and most delighted master. He informed the Prince that he had landed, and that the soil appeared to him unworked and fruitful; and, like a prudent man, he could not tell of foreign plants, but had brought some of them home with him in a barrel of the new-found earth--plants much like those which bear in Portugal the roses of Santa Maria. The Prince rejoiced to see them, and gave thanks to God, "as if they had been the fruit and sign of the promised land; and besought Our Lady, whose name the plants bore, that she would guide and set forth the doings in this discovery to the praise and glory of God and to the increase of his holy faith." After passing the Cape of Bojador there was a lull in Portuguese discovery, the period from 1434 to 1441 being spent in enterprises of very little distinctness or importance. Indeed, during the latter part of this period, the Prince was fully occupied with the affairs of Portugal. In 1437 he accompanied the unfortunate expedition to Tangier, in which his brother Ferdinand was taken prisoner, who afterward ended his days in slavery to the Moor. In 1438, King Duarte dying, the troubles of the regency occupied Prince Henry's attention. In 1441, however, there was a voyage which led to very important consequences. In that year Antonio Goncalvez, master of the robes to Prince Henry, was sent out with a vessel to load it with skins of "sea-wolves," a number of them having been seen, during a former voyage, in the mouth of a river about fifty-four leagues beyond Cape Bojador. Goncalvez resolved to signalize his voyage by a feat that should gratify his master more than the capture of sea-wolves; and he accordingly planned and executed successfully an expedition for capturing some Azeneghi Moors, in order, as he told his companions, to take home "some of the language of that country." Nuno Tristam, another of Prince Henry's captains, afterward falling in with Goncalvez, a further capture of Moors was made, and Goncalvez returned to Portugal with his spoil. In the same year Prince Henry applied to Pope Martin V, praying that his holiness would grant to the Portuguese crown all that it could conquer, from Cape Bojador to the Indies, together with plenary indulgence for those who should die while engaged in such conquests. The Pope granted these requests. "And now," says a Portuguese historian, "with this apostolic grace, with the breath of royal favor, and already with the applause of the people, the Prince pursued his purpose with more courage and with greater outlay."
