"There lived at Naples," says his biographer, Venanzio, "a rough incult lawyer, called Castagnola, covered with rust and dust, and an enemy to every thing that was not allied to forensic struggles and turmoils." Wishing to place a barrier between his will and his inclinations, Metastasio went to Naples, and chose this man for his master, believing that his asperity and detestation of poetry would serve to guard him against having again recourse to an art towards which nature impelled him. For nearly two years he submitted to the control of Castagnola, and devoted himself to the severest study. But he was well known at Naples, and his talents were appreciated. He was perpetually solicited to compose epithalamiums, theatrical pieces, and occasional verses. He resisted the temptation as long as he could: at last, commanded by the viceroy, he consented to write a drama, to celebrate the birthday of the empress Elizabeth Christina, wife of Charles VI. He, however, obtained a promise of secrecy, and hoped to conceal his crime from his master. To accomplish this, he was obliged to steal for his work the hours usually devoted to sleep; but his natural vein, checked for some time, flowed with such felicity, that he accomplished his task before the appointed time. The "Orti Esperidi" charmed his august employer, who bestowed on it the highest praise, and presented the author with a purse containing two hundred ducats. The success of this interlude on the stage confirmed the judgment of the viceroy. It was admirably set to music, and the decorations were most splendid. All Naples flocked to the representation--all Naples resounded with its praises, and every one was eager to thank and applaud the author. But Metastasio, reluctant to quit his legal studies, shrank from the censures of his master, and continued to preserve the concealment he had at first adopted: he even angrily denied the charge when he was accused of being the writer, and put enquiry to fault; till at last the discovery was made by the prima donna, Marianna Bulgarelli, usually called La Romanina, from her native city. She had received the greatest applause in the character of Venus, in this drama; and her gratitude and admiration made her eager to learn to whom she owed her success. Despite all his efforts, she discovered that Metastasio was the author, and she lost no time in spreading the report throughout Naples.
