The fourth, and last, imposture was more serious. This time the personator began in Venice in 1598, calling himself “Knight of the Cross.” As twenty years had now elapsed since the disappearance of Sebastian, he would have changed much in appearance, so in one respect the personator had less to contend against. Moreover the scene of endeavour was this time laid in Venice, a place even more widely removed in the sixteenth century from Lisbon by circumstances than by geographical position. Again witnesses who could give testimony to the individuality of the missing King of twenty years ago were few and far between. But on the other hand the new impostor had new difficulties to contend against. Henry, the Cardinal, had only occupied the Portuguese throne two years, for in 1580 Philip II of Spain had united the two crowns, and had held the dual monarchy for eighteen years. He was a very different antagonist from any one that might be of purely Portuguese origin. In the eyes of many of the people--like all the Latin races naturally superstitious--one circumstance powerfully upheld the impostor’s claim. So long ago as 1587, Don John de Castro had made a seemingly prophetic statement that Sebastian was alive and would manifest himself in due time. His utterance was, like most such prophecies of the kind, “conducive to its own fulfilment;” there were many--and some of them powerful--who were willing at the start to back up any initiator of such a claim. In his time Sebastian had been used, so far as it was possible to use a man of his temperament and position, by the intriguers of the Catholic Church, and the present occasion lent itself to their still-existent aims. Rome was very powerful four centuries ago, and its legions of adherents bound in many ties, were scattered throughout the known world. Be sure these could and would aid in any movement or intrigue which could be useful to the Church.
