The Crown of Portugal, upon the intelligence of Sebastian's death, devolved upon Don Henry, an elderly Cardinal, who, enjoying a brief reign of seventeen months, died without leaving any heirs. After a short but decisive struggle, Portugal fell an easy prey to Philip of Spain, but he was not long allowed to enjoy quiet possession of the usurped realm. The people had never credited the account of their idolized monarch's death, and rumour after rumour had been circulated to prove his existence. Three claimants to the name and title of the slain Sebastian arose, one after the other, to disturb and perplex the country, and afford the Spanish pretexts for further plunder and murder. Although these three played their part well, and occasioned the Government much trouble, there is little doubt as to their having been impostors; but over one, a fourth pretender, still hangs a cloud of impenetrable mystery.
This last aspirant appeared at Venice about twenty years after the battle of Alcaçarquivir, a very plausible account of his escape from which he was enabled to give, further stating that he had subsequently reached Portugal, and revealed his presence there to his great uncle Henry, who was then reigning; but as he had then stated that, sick and broken-hearted at his overthrow by the infidel, he had no present intention of resuming his sceptre, no notice was taken of the notification. As soon as his wounds were healed, the soi disant Don Sebastian stated, he, and two Portuguese nobles who were alleged to have saved themselves in his company, started on their travels, and travelled over Europe, Africa, and Asia, visiting the colonial possessions of Portugal, and even taking a personal share with the Persians in their war against the Turks. The King also paid visits to the Grand Llama of Thibet, and to Prester John in Ethiopia, encountering no end of marvellous adventures on his journeys, during which, however, his two companions, worn out with wounds and fatigues, succumbed to death. The royal wanderer then retired to a hermitage in the Georgian desert, and stayed there until the year 1597, when, admonished by a dream to resume his crown, he returned to Europe. He landed in Sicily, and at once despatched letters to several of his most attached nobles in Portugal. Catizoni, his messenger, was arrested on landing, and never heard of again; but through some unknown channels the tidings of which he was the bearer transpired, and threw the whole country into a profound state of excitement. Had the soi disant monarch had courage to have landed in Portugal at this time, it is pretty generally believed that, whatever may have been the value of his claims to the name of Don Sebastian, the whole people would have acknowledged his rights; as one writer says, the nation "would have acknowledged a negro to be their lost king, so that he delivered them from the hated rule of the Spaniards."
Wanting the resolution, or the means, to seek Portugal, the claimant fell from one state of wretchedness to another, until, at last, it is averred he was discovered by some compatriots in Padua selling pies in the street for a livelihood. Convinced that they had discovered their legitimate sovereign, the Portuguese residents and exiles at once acknowledged his claims, and supplied him with all the necessaries of life. Apprised of this event, the Spanish ambassador immediately requested the Venetian senate to banish the "insolent adventurer" from their states. The Podesta of Padua being commanded by the Seignory to banish from his city within three days "a man calling himself falsely Sebastian, King of Portugal," and this mandate being communicated to the soi disant monarch, he boldly repaired to Venice, and requested the Senate, the only free tribunal in Europe, to investigate his claims. Upon his arrival, he was seized and thrown into a dungeon, at the instance of Philip's ambassador, who suborned witnesses to accuse him of horrible crimes. This, however, caused his pretensions to be speedily noised about all over Europe. A large number of the Portuguese in Italy presented several petitions to the Senate, calling upon it to investigate the prisoner's claims, whilst Sampayo, a Dominican of considerable influence in Padua, wrote and published a full statement of the facts, and dedicated it to the potentates of Europe.
In the meantime the Spaniards were not idle. They averred that the claimant was a Calabrese impostor, of bad repute, if not a renegade monk; they alluded to the gross improbabilities in his story, and the little likelihood there was of Sebastian, even if he had escaped from the battle of Alcaçarquivir, remaining out of the pale of civilization for twenty years without affording anyone an intimation of his existence. They pointed out that the pretender's Portuguese was anything but pure, and that whereas Sebastian's complexion was fair this man's was dark.
Sampayo, on behalf of the prisoner, replied that the king's wounded pride at his defeat, and youthful feelings of self-dependence, had carried him into all his romantic wanderings, whilst his fair complexion and native accent had necessarily changed during twenty years' rambling in the sultry lands which he had visited.
Whilst this discussion was going on, the prisoner was being severely examined by the Venetian Senate, and displayed, so all averred, such knowledge of their most secret dealings with the true Don Sebastian as fairly startled them. He declared himself ready to undergo the punishment of death if his claims were proved to be unfounded, and petitioned that he might be personally examined for any marks which the King of Portugal had been known to possess. The Portuguese residents warmly supporting the latter part of the memorial, the Seignory granted their request, and sent Sampayo with a safe conduct to Lisbon to ascertain these distinctive marks, and to get a written declaration of them signed by competent people. After an absence of two months the Dominican returned, with an attestation, witnessed by persons who had been attached to the late royal household, and countersigned by the apostolical notary, as a proof of the document's genuineness.
During Sampayo's absence the Spanish Government had made such forcible representations to the Venetian Senate, that on his return the Doge stated "it did not beseem the Republic to take cognizance of the claims of the pretender to the Portuguese Crown, unless at the request of a member of the family of European potentates." Nothing daunted, the unwearied envoy of the soi disant Sebastian undertook a journey to Holland to procure the intervention of the House of Nassau. His exertions were aided by the warm support of several Portuguese nobles, and by the influence of Henry the Fourth of France, who, through his ambassador at Venice, intimated that if the Dutch intercession failed, France would take the claimant under her protection. The States of Holland, however, having requested the Italian Republic to proceed with the inquiry, the Spanish ambassador withdrew his protest, and commissioners were appointed to examine the prisoner for the bodily peculiarities which the king was known to have possessed.
These peculiarities were alleged to be "a right hand longer and larger than the left; the upper part of the arms longer than the part between the elbow and the wrist; a deep scar above the right eyebrow; a tooth missing from the lower jaw, and a large excrescence or wart on the instep of the right foot." An investigation of the prisoner was then made, in the presence of Sampayo, by four Venetian officers of justice; and they reported that not only were all these peculiarities found upon him, but that his head and face bore the scars of sabre wounds; whilst, when his jaw was being examined, he had asked whether Sebastian Nero, the Court barber at Lisbon, who had extracted the tooth, was still alive.
The next day this evidence was laid before the senate, which held a secret deliberation of four days' duration, shared in by the Spanish ambassador and Don Christavao de Portugal, an apparent advocate of the captive. The threats of Philip are alleged to have overpowered the intentions of the Seignory, and, accordingly when, at ten o'clock at night, on the fourth day of the conference, the claimant was brought before them, they, without expressing any opinion respecting his identity with Don Sebastian, simply repeated the mandate formerly sent to the Podesta of Padua, banishing the person who styled himself King of Portugal from the Venetian states within the space of three days. Sampayo, and the Portuguese with him, declare that a seat was provided for the prisoner; and that whilst he remained covered during the reading of the decree the senators stood around respectfully. This averred deference, and the evasion of a direct award after so lengthy and solemn an assemblage, confirmed even waverers in the belief that the pretender was indeed the true Sebastian.
Whatever may have been the belief or reason of the senate, they contented themselves with banishing the soi disant monarch, and refused to deliver him up to the Spanish ambassador. Countenanced by all the enemies of Spain, the claimant now sought refuge in Tuscany, en route, it is said, to Rome, to claim the protection and recognition of his claims by the reigning Pontiff, Clement the Eighth. The Grand Duke Ferdinand, desirous of propitiating his powerful foe Philip, is alleged to have made an agreement with him, that if the adventurer entered the Tuscan territories he should be at once arrested and delivered up to the custody of the Spanish. Be this as it may, the pretender was seized as he was attempting to leave the Grand Duke's dominions, put on board a small frigate, taken to Naples, and delivered up to the Conde de Lemos, Philip's viceroy.
