Several of his compositions, written at this time, are still performed in Rome on Good Friday, and Goethe and Mendelssohn have left their eloquent tributes to the impression made on them by music alike simple and sublime. The pope was highly pleased with Palestrina's noble music, and appointed him one of the papal choristers, then regarded as a great honor. But beyond Rome the new light of music was but little known. The Council of Trent, in their first indignation at the abuse of church music, had resolved to abolish everything but the simple Gregorian chants, but the remonstrances of the Emperor Ferdinand and the Roman cardinals stayed the austere fiat. The final decision was made to rest on a new composition of Palestrina, who was permitted to demonstrate that the higher forms of musical art were consistent with the solemnities of church worship. All eyes were directed to the young musician, for the very existence of his art was at stake. The motto of his first mass, "Illumina oculos meos," shows the pious enthusiasm with which he undertook his labors. Instead of one, he composed three six-part masses. The third of these excited such admiration that the pope exclaimed in raptures, "It is John who gives us here in this earthly Jerusalem a foretaste of that new song which the holy Apostle John realized in the heavenly Jerusalem in his prophetic trance." This is now known as the "mass of Pope Marcel," in honor of a former patron of Palestrina. A new pope, Paul IV., on ascending the pontifical throne, carried his desire of reforming abuses to fanaticism. He insisted on all the papal choristers being clerical. Palestrina had married early in life a Roman lady, of whom all we know is that her name was Lucretia. Four children had blessed the union, and the composer's domestic happiness became a bar to his temporal preferment. With two others he was dismissed from the chapel because he was a layman, and a trifling pension allowed him. Two months afterward, though, he was appointed chapel-master of St. John Lateran. His works now succeeded each other rapidly, and different collections of his masses were dedicated to the crowned heads of Europe. In 1571 he was appointed chapel-master of the Vatican, and Pope Gregory XIII. gave special charge of the reform of sacred music to Palestrina.
