"Giovanni Pierluigi da Palestrina (c. 1525 – 2 February 1594) was an Italian Renaissance composer of sacred music and the best-known 16th-century representative of the Roman School of musical composition. He has had a lasting influence on the development of church music, and his work has often been seen as the culmination of Renaissance polyphony." - Wikipedia
Marco Antonio Ingegneri
"Marc'Antonio Ingegneri (also spelled Ingegnieri, Ingignieri, Ingignero, Inzegneri) (c. 1535 or 1536 – 1 July 1592) was an Italian composer of the late Renaissance. He was born in Verona and died in Cremona. Even though he spent most of his life working in northern Italy, because of his stylistic similarity to Palestrina he is often considered to be a member of the Roman School of polyphonic church music. He is also famous as the teacher of Claudio Monteverdi. Ingegneri was close friends with Bishop Nicolò Sfondrato, later Pope Gregory XIV, who was intimately involved with the reforms of the Counter-Reformation and the Council of Trent, and this influence is present in his music, which usually shows the simplification and clarity of the Palestrina style. Indeed, his book of twenty-seven Responsoria was long misattributed to Palestrina. However, some of his music quite ignores the reformist dicta of the Council; most notorious is a four-voice motet Noe noe, which is a double canon by inversion, in which it would require an exceedingly keen ear to hear the text: and intelligibility of the text was the one demand made by the Council of Trent of any composer of sacred polyphony." - Wikipedia
