Sir: I have already given you a legend or two drawn from ancient Spanish sources, and may occasionally give you a few more. I love these old Spanish themes, especially when they have a dash of the Morisco in them, and treat of the times when the Moslems maintained a foot-hold in the peninsula. They have a high, spicy, oriental flavor, not to be found in any other themes that are merely European. In fact, Spain is a country that stands alone in the midst of Europe; severed in habits, manners, and modes of thinking, from all its continental neighbors. It is a romantic country; but its romance has none of the sentimentality of modern European romance: it is chiefly derived from the brilliant regions of the East, and from the high-minded school of Saracenic chivalry. The Arab invasion and conquest brought a higher civilization and a nobler style of thinking into Gothic Spain. The Arabs were a quick-witted, sagacious, proud-spirited, and poetical people, and were imbued with oriental science and literature. Wherever they established a seat of power, it became a rallying place for the learned and ingenious; and they softened and refined the people whom they conquered. By degrees, occupancy seemed to give them a hereditary right to their foothold in the land; they ceased to be looked upon as invaders, and were regarded as rival neighbors. The peninsula, broken up into a variety of states, both Christian and Moslem, became for centuries a great campaigning ground, where the art of war seemed to be the principal business of man, and was carried to the highest pitch of romantic chivalry. The original ground of hostility, a difference of faith, gradually lost its rancor. Neighboring states, of opposite creeds, were occasionally linked together in alliances, offensive and defensive; so that the cross and crescent were to be seen side by side fighting against some common enemy. In times of peace, too, the noble youth of either faith resorted to the same cities, Christian or Moslem, to school themselves in military science. Even in the temporary truces of sanguinary wars, the warriors who had recently striven together in the deadly conflicts of the field, laid aside their animosity, met at tournaments, jousts, and other military festivities, and exchanged the courtesies of gentle and generous spirits. Thus the opposite races became frequently mingled together in peaceful intercourse, or if any rivalry took place, it was in those high courtesies and nobler acts which bespeak the accomplished cavalier. Warriors of opposite creeds became ambitious of transcending each other in magnanimity as well as valor. Indeed, the chivalric virtues were refined upon to a degree sometimes fastidious and constrained; but at other times, inexpressibly noble and affecting. The annals of the times teem with illustrious instances of high-wrought courtesy, romantic generosity, lofty disinterestedness, and punctilious honor, that warm the very soul to read them.
