Henry now began to please himself with the success of his projects, and, as one of his purposes was the conversion of infidels, he thought it necessary to impart his undertaking to the pope, and to obtain the sanction of ecclesiastical authority.  To this end Fernando Lopez d’Azevedo was despatched to Rome, who related to the pope and cardinals the great designs of Henry, and magnified his zeal for the propagation of religion.  The pope was pleased with the narrative, and by a formal bull, conferred upon the crown of Portugal all the countries which should be discovered as far as India, together with India itself, and granted several privileges and indulgences to the churches which Henry had built in his new regions, and to the men engaged in the navigation for discovery.  By this bull all other princes were forbidden to encroach upon the conquests of the Portuguese, on pain of the censures incurred by the crime of usurpation.

The approbation of the pope, the sight of men, whose manners and appearance were so different from those of Europeans, and the hope of gain from golden regions, which has been always the great incentive to hazard and discovery, now began to operate with full force.  The desire of riches and of dominion, which is yet more pleasing to the fancy, filled the court of the Portuguese prince with innumerable adventurers from very distant parts of Europe.  Some wanted to be employed in the search after new countries, and some to be settled in those which had been already found.

Communities now began to be animated by the spirit of enterprise, and many associations were formed for the equipment of ships, and the acquisition of the riches of distant regions, which, perhaps, were always supposed to be more wealthy, as more remote.  These undertakers agreed to pay the prince a fifth part of the profit, sometimes a greater share, and sent out the armament at their own expense.

The city of Lagos was the first that carried on this design by contribution.  The inhabitants fitted out six vessels, under the command of Lucarot, one of the prince’s household, and soon after fourteen more were furnished for the same purpose, under the same commander; to those were added many belonging to private men, so that, in a short time, twenty-six ships put to sea in quest of whatever fortune should present.

The ships of Lagos were soon separated by foul weather, and the rest, taking each its own course, stopped at different parts of the African coast, from cape Blanco to cape Verd.  Some of them, in 1444, anchored at Gomera, one of the Canaries, where they were kindly treated by the inhabitants, who took them into their service against the people of the isle of Palma, with whom they were at war; but the Portuguese, at their return to Gomera, not being made so rich as they expected, fell upon their friends, in contempt of all the laws of hospitality and stipulations of alliance, and, making several of them prisoners and slaves, set sail for Lisbon.
