I am well acquainted with the medal described by Mr. Nightingale, and can confirm his statement of the difficulties which numismatists have experienced in attempting to explain the circumstances alluded to by the lobster which is the badge of "the order of the pretended Prince of Wales," and upon which, on the other side of the medal, Father Petre is represented as riding with the young prince in his arms. Upon other medals also the Jesuit appears carrying the prince, who is decorated, or amusing himself, with a windmill. There is likewise a medal on which a Jesuit is represented concealed within a closet or alter, and raising or pushing up through the top the young prince to the view of the people, while Truth is opening the door and exposing the imposition. Similar representations of the Jesuit's interference occur upon caricatures and satirical prints executed in Holland. Upon one, entitled, "Arlequin sur l'Hippogryphe, a la croisade Lojoliste," the lobster, on which the Jesuit is mounted, carries a book in each claw; the young prince's head is decorated with a windmill. All these intimate the influence of Father Petre upon the proceedings of James II, and of the Jesuits in general in the imposition, as was by many supposed, of the pretended prince. The imputation upon the legitimacy of the young child was occasioned in a great degree, and almost justified, by the pilgrimages and superstitious fooleries of his grandmother, increased by his mother's choosing St. Francis Xavier as one of her ecclesiastical patrons, and with her family attributing the birth of the prince to his miraculous interference. This may have provoked the opposers of popery to take every means of satirising the Jesuits; and the following circumstances related in the _Life of Xavier_ probably suggested the idea of making the lobster one of the symbols of the superstitions and impositions of the Jesuits, and a means of discrediting the birth of the prince by ridiculing the community by whose impositions they asserted the fraud to have been contrived and executed. The account is given by a Portuguese, called Fausto Rodriguez, who was a witness of the fact, has deposed it upon oath, and whose juridical testimony is in the process of the Saint's canonization.
