Among the nobility by whom he was surrounded, Sebastian distinguished Antonio, prior of Crato; who, though an illegitimate son of the late Duke de Beja, was considered throughout Portugal as the King’s acknowledged relation.
In conformity with the customs of those times, Antonio had taken the vow of celibacy, in order to qualify him for holding the rich priory of Crato, and the grand mastership of the knights of Malta: in other respects he possessed nothing of the priest. Nature had endowed him with an animating cheerfulness of disposition, to which every one resorted for pleasure: he was liberal of his purse, liberal even to carelessness in his judgments; naturally indolent and indifferent in matters of importance; but capable of catching the fever of enthusiasm from another. This last quality gave him his influence over Sebastian.
The king was flattered by the appearance of having roused Antonio from a degrading apathy: for, indeed, except in the prior’s attachment to him, he seemed devoid of any serious feeling. Every impression left by beauty, by accomplishments, by goodness, by wisdom, by affairs of the state or the church, passed off from his volatile mind, like sand drifted by the wind. He laughed and trifled with Sebastian, alternately delighted and provoked him, for ever beguiled him with the prospect of improvement, and for ever disappointed him: but it was this unsubstantial character which fixed him in Sebastian’s heart. A character which received the best impressions with the most seducing facility, yet never retained, and always lamented them, was expressly formed to excite partial solicitude. Antonio became by degrees his constant companion, his most intimate confidant, and at length his chief counsellor.
The deaths of Meneses and Camera, which happened in the course of the same year, greatly affected Sebastian, although these events left him more freely to the bent of his own inclination: He could now renew his resolution of plunging into a religious war, without apprehension of being restrained by opinions to which he was used to yield. The habit of believing this resolution highly meritorious, had given some imperiousness to his mode of carrying it into execution; and he could not always conceal his disdain for such persons as represented that no zeal for general good, should make him risk the particular good of his own subjects. But towards Antonio, he turned with redoubled favor; for Antonio warmly embraced the revived projects, offering to accompany him into Africa, a country now become the object of his contemplation.
The Moors, though driven out of Spain, still continued to increase in strength and dominion among the mountains of Barbary: they frequently attacked the fortresses belonging to Portugal, which remained to her upon their coast, and not only treated the prisoners made in these engagements with extreme rigour, but terrified or seduced some of them into the profession of their impious faith. Sebastian meditated the destruction of this growing power: he communicated his design to Antonio alone, who consented to become his companion in a secret excursion to the fortress of Tangier, from whence they might gather certain information of the nature and the resources of the Mauritanian states.
As it was the young king’s wish to avoid controversy with his ministers, by keeping the whole affair secret till he had reconnoitred Africa, Don Antonio was directed to make private arrangements for their conveyance beyond sea, while under the pretence of a hunting match, he should draw together all the young lords likely to embrace their enterprize.
Gallantly provided, those favorite nobles met their sovereign in the province of Algarve, where he disclosed his project of crossing over immediately into Africa. Smit with the phrensy of chevalric adventure, every one consented to embark their fates with those of their King; and rather to incur the chance of being taken prisoners by the Moors, than shrink from danger when it might lead to glory.
They set sail in a single vessel badly manned and worse armed; but to a band of rash young men, whose leader was still younger, and more adventurous than themselves, even hazard had charms. After a short voyage, they landed safely at Tangier.
Sebastian was no sooner upon African ground, than he began to prosecute his enquiries with equal vigour and ability: he learnt the military force and resources of the Moors, their points of weakness and of strength, their system of war and of government, the nature of their troops, and the topography of their country; he ransomed several Christians who had long languished in slavery, and from their accounts of the Moorish princes began to hope that in their contests for supremacy, he might reap solid advantage.
Having thoroughly acquainted himself with these important subjects, the King hastened his re-embarkation: flushed with the conviction of being now able to bear down every cautionary suggestion of his counsellors, by arguments drawn from actual observation of the country he was going to invade. After a short absence he set sail again with his followers for the shores of Portugal.
