Metastasio (1698-1782) gave early indications of genius, and when only ten years of age used to collect an audience in his father's shop, by his talent for improvisation. He thus attracted the notice of Gravina, a celebrated patron of letters, who adopted him as his son, changed his somewhat ignoble name of Trepassi to Metastasio, and had him educated in every branch necessary for a literary career. He still continued to improvise verses on any given subject for the amusement of company. His youth, his harmonious voice, and prepossessing appearance, added greatly to the charm of his talent. It was one generally cultivated in Italy at this time, and men of mature years often presented themselves as rivals of the hoy. This occupation becoming injurious to the youth, Gravina forbade him to compose extempore verses any more, and this rule, imposed on him at sixteen, he never afterwards infringed. When Metastasio was in his twentieth year Gravina died, leaving to him his fortune, most of which he squandered in two years. He afterwards went to Naples, where, under a severe master, he devoted himself to the closest study and for two years resisted every solicitation to compose verses. At length, under promise of secrecy, he wrote a drama. All Naples resounded with its praise, and the author was soon discovered. Metastasio from this time followed the career for which nature seemed to have formed him, and devoted himself to the opera, which he considered to be the natural drama of Italy. An invitation to become the court poet of Vienna made his future life both stable and prosperous. On the death of Charles VI., in 1740, several other European sovereigns made advantageous overtures to the poet, but as Maria Theresa was disposed to retain him, he would not leave her in her adverse circumstances. The remainder of his life he passed in Germany, and his latter years were as monotonous as they were prosperous.
Metastasio seized with a daring hand the true spirit of the melodrama, and scorning to confine himself to unity of place, opened a wide field for the display of theatrical variety, on which the charm of the opera so much depends. The language in which he clothed the favorite passion of his drama exhibits all that is delicate and yet ardent, and he develops the most elevated sentiments of loyalty, patriotism, and filial love. The flow of his verse in the recitative is the most pure and harmonious known in any language, and the strophes at the close of each scene are scarcely surpassed by the first masters in lyric poetry. Metastasio is one of the most pleasing, at the same time one of the least difficult of the Italian poets, and the tyro in the study of Italian classics may begin with his works, and at once enjoy the pleasures of poetic harmony at their highest source.
