The short lives of the illegitimate branch of the House of Castile, and their personal insignificance, intensified rather than detracted from the dramatic vicissitudes of their reigns.
Juan, son of Enrique de Trastamare (1390), died young by a fall from his horse. His son, El Enfermo, who ended his life at twenty-eight, inaugurated the romantic episode of the Regents. The infancy of Juan II. called forth the powerful personality of the Conde de Luna, and the vice and folly of Enrique IV. brought forward his sister Isabel, wife of Ferdinand the Catholic, into extraordinary prominence in the politics of Europe.
At this time Queen Catalina holds her court at Burgos—a fat, foolish dowager, by no means inheriting the fierce passions of her grandparents—Don Pedro el Cruel and Maria de Padilla. In close alliance with the highly cultivated Moors, as had been her husband El Enfermo, Catalina also favours the fine arts, and educates her son to love those elegant cancioneros sung by her husband with such art, the metre of which will never be surpassed.
Hundreds of these romances, current in that day, were softened and refined into real poetry, and as such have come down to us as absolute gems. Long stories in prose too, such as Amadis de Gaul, began now to be written, to be followed by the Romaunt of the Rose, as also many learned treatises on government and science, taken from the Arabic; and, wonder of wonders, Don Pedro Ayala actually translated Livy into Spanish!
In this literary movement the good Queen Catalina took part, and inducted her little son into an amount of learning remarkable in that age. He was fond of books and could speak and versify fluently in Latin. Courage he had, and knowledge he acquired, growing up under his mother’s care a gentle, indolent young prince like his father, but absolutely without will, which made him a prey to the first resolute spirit who gained his confidence.
Such a one was found in the person of Don Alvarez de Luna, Conde de Gormaz, the last representative of the ideal Knight of Spain. Bold, romantic, brave, his masterful individuality imposed itself on the artistic temperament of the young king much as an eagle might foster and protect a helpless dove.
As the descendant of a noble Biscayan family, whose ancestors had done good service to Enrique de Trastamare in his many sudden flights and rapid advances in the wild passes of the Pyrenees, Luna had claims on the young king. Ever the prominent figure in court and camp, Don Juan from his birth had been thrown into his companionship, whose handsome person and courtly manners charmed his boyish taste and resulted in an ascendancy so absolute as to absorb all the power of the state. Nor could remonstrance, conspiracy, or open acts of revolt for many years shake his position. Indeed, opposition only seemed to endear him to Don Juan, who rapidly advanced him to the high office of Constable of Castile and Leon and Grand Master of Santiago.
Possessed of the entire love and confidence of his master, the court was filled with his kindred and partisans; Don Juan saw with his eyes and regulated every action at his pleasure. Even in the matter of his marriage, instead of uniting himself to the French Princess Fredegonde, whom he preferred, at Luna’s desire he espoused his cousin, Doña Isabel of Portugal.
Such an excess of favour naturally raised an immense animosity against him. Every noble and ricohombre in Castile hated him on his own account. The Infante of Aragon headed a party to dethrone him. All this at length coming to the knowledge of Don Juan, caused him throes of extreme doubt as to his conduct, overruled for a time by the masterful will of Luna, but to bear fruit at length as the consequence of the inherent weakness of his nature.
Young as he still was, Don Juan had been twice married. The new queen, his cousin, was a dark-complexioned beauty, with a skin like a ripe peach and the keen black eyes of a Zingara. No sooner had she arrived at Burgos than she came to understand that she owed her position solely to the favour of Luna, and that Don Juan would have preferred the French princess. Nothing could be more galling to her pride, and Isabel was very proud. At once she resolved upon his ruin, and steadily carried out her plan. If Juan was to be governed by a favourite, it should be herself.
