This belief was a very natural one. The fact of Charles being a Protestant had been the stumbling-block in the way of the match. A dispensation for the marriage of a Catholic princess with the Protestant prince of England had been asked from the pope, but had not yet been given. Charles had come to Madrid with the empty hope that his presence would cut the knot of this difficulty, and win him the princess out of hand. The authorities and the people, on the contrary, fancied that nothing less than an intention to turn Catholic could have brought him to Spain. As for the infanta herself, she was an ardent Catholic, and bitterly opposed to being united in marriage to a heretic prince. Such was the state of affairs that prevailed. The easy pathway out of the difficulty which the hopeful prince had devised was likely to prove not quite free from thorns. [Illustration: THE ROYAL PALACE, MADRID.] The days passed on. Buckingham declared to Olivares that Charles had no thought of becoming a Catholic. Charles avoided the subject, and talked only of his love. The Spanish ministers blamed Bristol for his indecision, and had rooms prepared for the prince in the royal palace. Charles willingly accepted them, and on the 16th of March rode through the streets of Madrid, on the right hand of the king, to his new abode. The people were now permitted to applaud to their hearts' desire, as no further pretence of a secret existed. Glad acclamations attended the progress of the royal cortege. The people shouted with joy, and all, high and low, sang a song composed for the occasion by Lope de Vega, the famous dramatist, which told how Charles had come, under the guidance of love, to the Spanish sky to see his star Maria. "Carlos Estuardo soy Que, siendo amor mi guia, Al cielo d'Espana voy Por ver mi estrella Maria." The palace was decorated with all its ancient splendor, the streets everywhere showed signs of the public joy, and, as a special mark of royal clemency, all prisoners, except those held for heinous crimes, were set at liberty, among them numerous English galley-slaves, who had been captured in pirate vessels preying upon Spanish commerce. Yet all this merrymaking and clemency, and all the negotiations which proceeded in the precincts of the palace, did not expedite the question at issue. Charles had no thought of becoming a Catholic. Philip had little thought of permitting a marriage under any other conditions. The infanta hated the idea of the sacrifice, as she considered it. The authorities at Rome refused the dispensation. The wheels of the whole business seemed firmly blocked.
