The work in the riding-school was at last approaching completion.  It had occupied far more than the year in which it was to have been finished, and His Majesty’s impatience had become so great, that Coello was compelled to leave everything else, to paint only there, and put his improving touches to Ulrich’s labor.

The time for departure was drawing near.  The hanging-scaffold, on which he had lain for months, working on the master’s pictures, had been removed, but there was still something to be done to the walls.

Suddenly the court-artist was ordered to suspend the work, and have the beams, ladders and boards, which narrowed the space in the picadero,—­ [Riding School]—­removed.

The large enclosure was wanted during the next few days for a special purpose, and there were new things for Coello to do.

Don Juan of Austria, the king’s chivalrous half-brother, had commenced his heroic career, and vanquished the rebellious Moors in Granada.  A magnificent reception was to be prepared for the young conqueror, and Coello received the commission to adorn a triumphal arch with hastily-sketched, effective pictures.

The designs were speedily completed, and the triumphal arch erected in a court-yard of the Alcazar, for here, within the narrow circle of the court, not publicly, before the whole population, had the suspicious monarch resolved to receive and honor the victor.

Ulrich had again assisted Coello in the execution of his sketches.  Everything was finished at the right time, and Don Juan’s reception brilliantly carried out with great pomp and dignity, through the whole programme of a Te Deum and three services, processions, bull-fights, a grand ‘Auto-da-fe’, and a tournament.

After this festival, the king again resigned the riding-school to the artists, who instantly set to work.  Everything was finished except the small figures at the bottom of the larger pictures, and these could be executed without scaffolding.

Ulrich was again standing on the ladder, for the first time after this interruption, and Coello had just followed him into the picadero, when a great bustle was heard outside.

The broad doors flew open, and the manege was soon filled with knights and ladies on foot and horseback.

The most brilliant figures in all the stately throng were Don Juan himself, and his youthful nephew, Alexander Farnese, Prince of Parma.

Ulrich feasted his eyes on the splendid train, and the majestic, haughty, yet vivacious manner of the conqueror.

Never in his life, he thought, had he seen a more superb youthful figure.  Don Juan stopped directly opposite to him, and bared his head.  The thick, fair hair brushed back behind his ears, hung in wonderfully soft, waving locks down to his neck, and his features blended feminine grace with manly vigor.

As, hat in hand, he swung himself from the saddle, unassisted, to greet the fair duchess of Medina Celi, there was such a charm in his movements, that the young artist felt inclined to believe all the tales related of the successful love affairs of this favorite of fortune, who was the son of the Emperor Charles, by a German washerwoman.
