Which Italian Renaissance composer of sacred music had an important role in the Counter-Reformation?
Tomás Luis de Victoria Tomás Luis de Victoria (sometimes Italianised as "da Vittoria"; c. 1548 – 27 August 1611) was the most famous composer in 16th-century Spain, and was one of the most important composers of the Counter-Reformation, along with Giovanni Pierluigi da Palestrina and Orlando di Lasso. Victoria was not only a composer, but also an accomplished organist and singer as well as a Catholic priest. However, he preferred the life of a composer to that of a performer.
Zacara da Teramo Antonio "Zacara" da Teramo (in Latin Antonius Berardi Andree de Teramo, also Zacar, Zaccara, Zacharie, Zachara, and Çacharius; b. probably between 1350 and 1360 – d. between May 19, 1413 and mid-September 1416) was an Italian composer, singer, and papal secretary of the late Trecento and early 15th century. He was one of the most active Italian composers around 1400, and his style bridged the periods of the Trecento, "ars subtilior", and beginnings of the musical Renaissance.
