In the course of a historical narrative like the present it must be borne in mind (amongst other things) that in the fifteenth century, men ripened more quickly than in the less strenuous and more luxurious atmosphere of our own day. Especially in the Tudor epoch physical gifts counted for far more than is now possible; and as early (and too often sudden) death was the general lot of those in high places, the span of working life was prolonged rather by beginning early than by finishing late. Even up to the time of the Napoleonic Wars, promotion was often won with a rapidity that would seem like an ambitious dream to young soldiers of to-day. Perkin Warbeck, born in 1474, was nineteen years of age in 1493, at which time the Earl of Kildare spoke of “this French lad,” yet even then he was fighting King Henry VII, the Harry Richmond who had overthrown at Bosworth the great and unscrupulous Richard III. It must also be remembered for a proper understanding of his venture, that Perkin Warbeck was strongly supported and advised with great knowledge and subtlety by some very resolute and influential persons. Amongst these, in addition to his Irish “Cousins” Kildare and Desmond, was Margaret, Duchess of Burgundy, sister of Edward IV, who helped the young adventurer in his plot by “coaching” him up in the part which he was to play, to such an extent that, according to Lord Bacon, he was familiar with the features of his alleged family and relatives and even with the sort of questions likely to be asked in this connection. In fact he was, in theatrical parlance, not only properly equipped but “letter-perfect” in his part. Contemporary authority gives as an additional cause for this personal knowledge, that the original Jehan de Warbecque was a converted Jew, brought up in England, of whom Edward IV was the godfather. In any case it may in this age be accepted as a fact that there was between Edward IV and Perkin Warbeck so strong a likeness as to suggest a _prima facie_ possibility, if not a probability, of paternity. Other possibilities crowd in to the support of such a guess till it is likely to achieve the dimensions of a belief. Even without any accuracy of historical detail there is quite sufficient presumption to justify guess-work on general lines. It were a comparatively easy task to follow the lead of Walpole and create a new “historic doubt” after his pattern, the argument of which would run thus:
